AB  - Two populations of Amaranthus retroflexus with different morphology were collected from field of the Maize Research Institute Zemun Polje, Serbia. Random amplified polymorphic DNA (RAPD) and seed protein analysis were performed to study the genetic differences in two grain Amaranthus populations. The studied populations have different protein and DNA profile. A total of 171 DNA fragments were generated by 31 RAPD primers, with an average of 5.5 fragments per primer. Of these, 61.4% fragments were polymorphic among the two populations. 18 protein fraction were obtained by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS PAGE). The populations differed in the four protein fractions of different molecular weight. The seed protein electrophoresis and RAPD markers are useful for genetic determination of A. retroflexus populations and identification of biotypes with atypical morphology.

AB  - A field experiment was conducted in order to estimate the influence of different arrangement patterns of maize plants (Zea mays L.) in combination with low rates of herbicides on weed infestation and on production parameters of the crop. The maize was sown at 70-, 50-, and 35-cm row space with the same crop density. The weed biomass declined with smaller row spaces and was, on average, the lowest with the 35-cm row space; even though the arrangement patterns of the maize plants had no significant effect on the average values of the weed biomass. The interaction of the arrangement pattern and the herbicide rate significantly influenced weed biomass. Maize grain yield expressed the greatest variation under the effects of applied factors, but did not differ significantly between treatments with the full and the half rate of herbicides. The results indicate that it is possible to control weed infestation level if maize is grown with increased spatial uniformity and combined application of other practices such are herbicides. In such a way, maize plants are more competitive against weeds and even lower amounts of herbicides could be applied in order to achieve high yields.

AB  - The arrangement pattern, i.e. shape and size of vegetative space available to growing plants influences crop-weed competitive interaction and weed abundance. Most researches show that growing row crops such as maize, soybean, sunflower etc., with narrow row space, has as a result lower weed infestation and better yield parameters. In this study the effects of the maize vegetative space, which are achieved with combination of different row spaces and spaces between plants in the row, on the weed distribution and fresh matter and some morphological and productive parameters of maize were investigated. The crop density was the same for all arrangement patterns and herbicide application was included with three levels: full and half of the recommended dose and control without herbicide application. In all three years of investigation, the weed fresh matter declined with decreasing row spaces and was, on average, the lowest for the narrower row space and herbicide application at recommended doses (38,6; 12,8 and 351,1 g m-2). In such arrangement pattern of maize plants, significant influence on the fresh matter of D. stramonium, S. nigrum and A. retroflexus, was achieved. Herbicide application at half of the recommended dose also significantly influenced level of weediness compared to untreated control. The size of maize vegetation space significantly influenced grain yield in 2005 and 2006, otherwise, the herbicide application had a significant influence on maize yield in all years. Grain yield did not differ significantly according to LSD-test between treatments with full and half rate of herbicides.

AB  - High weed infestation of seed crops often makes various measures that should be performed at the optimum time difficult, hence post-emergence herbicides have become the usual way of weed control in maize seed crops. The introduction of sulfonylurea herbicides has resulted in a higher susceptibility in maize inbreds. The aim of this study was to examine the effects of six post-emergence herbicides, including sulfonylurea herbicides, on the contents of fresh matter, soluble proteins, free thiolic groups and total phenolics in one-month-old plants, as well as on the grain yield of 15 commercial ZP maize inbred lines. The obtained results show that inbred plants have a whole range of responses to herbicide application. The changes in content of phenolics did not vary over a broad range among the applied herbicides; they followed mainly the level observed in control plants. However, greater variations between the results were obtained for the content of free thiolics, which are defenders against oxidative attack. The overall influence of herbicides could be considered as a decrease in the content of thiolics. Most of the applied herbicides expressed temporary stress, evidenced by a decrease in the fresh matter of the shoots, without affecting of yield at the end of vegetation. This could be connected to recovery mechanisms that include the activity of antioxidants, primarily of thiolics.

AB  - This paper presents the analysis of results obtained during long- term studies on the response of maize inbred lines to herbicides. Under the agroecological conditions of Zemun Polje the response (reaction of maize inbred lines to herbicides of different classes was investigated. Biological tests were performed and some agronomic, morphological, physiological and biochemical parameters were determined when the response of maize inbred lines to herbicides was estimated. The use of active ingredients of herbicides from triazine, acetanilide, thiocarbamate to new chemical groups (sulfonylurea etc.), have been resulted in changes in weed suppression and susceptibility of inbred lines. Obtained results show that effects of herbicides on susceptible maize genotypes can be different: they can slowdown the growth and development and affect the plant height; they can also affect the stages of the tassel and ear development and at the end they can reduced grain yield of the tested inbreds. Numerous studies confirmed the existence of differences in susceptibility level of maize genotypes in relation to herbicides. According to gained results the recommendations for growers are made on the possibility of the application of new herbicides in the hybrid seed production.

AB  - Widespread distribution of weeds in seed maize crops has resulted in frequent application of postemergence herbicides. Herbicides used in hybrid crops are also used in maize seed production, including sulphonylurea herbicides and other new compounds for suppression of annual and perennial weeds. Due to differences in susceptibility of maize inbred lines, none of these herbicides has been approved for maize hybrid seed production. On the other hand, due to an increase in weed infestation, they are used in practice. Faster or slower growth of crops and weeds, as well as herbicide uptake, generally depend on meteorological conditions (temperatures and precipitation sums). As knowledge of the different responses of maize inbred lines to herbicides is important to maize breeders, seed producers and weed scientists, we have investigated the effects of new herbicides on maize inbreds over a number of years.

AB  - Relations (interactions) between plants can be favourable, adverse or neutral. Competition is the most widespread form of adverse interaction in agrophytocoenoses. One generally accepted definition of competition is: 'Mutual confrontation of organisms (species, populations) on an occasion of usage of natural resources under conditions of their deficit'. Competition is a dynamic process and besides interspecific competition (crop-weed) there always occurs intraspecific competition (crop-crop or weed-weed). The competitive ability of plants can be expressed in the following two ways: 1) a crop ability to competitively affect weeds by reducing their biomass and seed production and 2) a crop ability to tolerate competitive activities of weeds resulting at the same time in high yields. Competition, as the most common interaction between a crop and a weed, depends on many factors and can be widely applied within weed control systems in practice. Weed control measures are one of natural or alternative methods of suppression of weed distribution as the interest in control measures based on reduced application of herbicides has increased during the last decade. The application of cultivation measures by which a crop-to-weed interaction is affected by inclusion of more competitive genotypes, crop densities, plant spatial patterns, ratios and locations of mineral fertiliser application, etc., has opened a new field of research of the crop-to-weed interaction. The intensity of crop competitive activities, especially of broadcast crops such as maize, is mainly determined by the density and spatial arrangement of plants.
AB  - Odnosi (interakcije) između biljaka mogu biti pozitivni, negativni i neutralni. Kompeticija je najzastupljeniji oblik negativnih interakcija u agrofitocenozama. Jedna od opšte prihvaćenih definicija kompeticije je: 'Međusobno suprotstavljanje organizama (vrste, populacije) prilikom iskorišćavanja prirodnih resursa u uslovima njihovog deficita'. Kompeticija je dinamičan proces i pored interspecijske (usev-korov), uvek dolazi i do intraspecijske kompeticije (usev-usev ili korov-korov). Kompetitivna sposobnost biljaka se može ispoljiti na dva načina. Prvi način je sposobnost useva da kompeticijski deluje na korove, smanjujući njihovu biomasu i produkciju semena. Drugi način je sposobnost useva da toleriše kompeticijsko delovanje korova dajući istovremeno visoke prinose. Kompeticija kao najčešći oblik interakcija između useva i korova zavisi od mnogih faktora i može imati široku praktičnu primenu u sistemu mera za kontrolu zakorovljenosti. Mere kontrole korova su jedan od prirodnih ili alternativnih načina rešavanja problema zakorovljenosti jer je u poslednjih desetak godina poraslo interesovanje za mere suzbijanja korova koje se manje oslanjaju na primenu herbicida. Kao rezultat, primena mera gajenja kojima se deluje na interakcije usev-korov kao što su kompetitivniji genotipovi, gustina gajenja useva, prostorni raspored gajenih biljaka, količina i mesto primene mineralnih đubriva i dr., uticala je na stvaranje novog prostora za istraživanja u oblasti interakcija između useva i korova.

AB  - The intensity of crop competition is mostly defined by population density and spatial arrangement of plants. The effect of plant arrangement pattern of maize, in combination with the application of different herbicide rates, on weediness and maize yields were studied at the Maize Research Institute, Zemun Polje, during 2004 and 2005. Different plant arrangement patterns were designed by combining three inter-row distances (70, 50 and 35 cm) as well as by plant spacing at uniform population density. Subvariants included the application of isoxaflutole + acetochlor herbicides after sowing but prior to maize emergence at three rates: recommended, half of the recommended rate and without herbicide treatment. The number of plants per species, fresh weight of weeds, biomass and grain yield of maize were analysed. Although there were no statistical significances, the number of plants per species and fresh weight of weeds declined with the decrease in inter-row distance and, on the average, their values were the lowest in the 35-cm variant in both years 2004 and 2005 (78.52 plants m-2 and 388.65 g m-2 vs. 105.78 plants m-2 and 191.54 g m-2, respectively). The different rates of herbicide application significantly affected weediness by reducing it in both years of investigation. Maize grain yield did not vary over treatments with the recommended and half the recommended rate at the different inter-row distances and on the average.

Only the resistance to the Pivot herbicide was obviously found (active ingredient imazethapyr), and the genes controlling this trait were dominant. Few modes of inheritance were found for these genes (three complementary dominant genes, two complementary dominant genes and one dominant gene). For practical purposes (incorporation in the non-resistant material), the source of one dominant gene is the most appropriate.

The following herbicides were applied in the 2-3-leaf stage of maize: isoxaflutole (Merlin 750-WG) in the amount of 0.135 kg ha-1, nicosulfuron (Motivell) in the amount of 1.25 l ha-1, foramsulfuron (Equip) in the amount of 2.0 l ha-1, dicamba + rimsulfuron (Tarot plus) in the amount of 0.3 kg ha-1, mezotrion (Callisto) in the amount of 0.25 l ha-1 and thifensulfuron-methyl (Grid) in the amount of 0.02 kg ha-1. The phytotoxic effect of herbicides on the maize grain yield was evaluated according to the 1-9 EWRC scale. Maize inbreds showed different susceptibility depending on the applied herbicide. The least favourable effects in both years for all genotypes were obtained in the treatments with Tarot plus and Grid, in which the lowest values of maize grain yield were recorded.
AB  - U radu je ispitivana reakcija četiri samooplodne linije, roditeljskih komponenti ZP hibrida kukuruza na delovanje šest herbicida primenjenih posle nicanja kukuruza i korova (postemergence). U fazi 2-3 lista kukuruza primenjeni su sledeći herbicidi: izoksaflutol (Merlin 750-WG) u količini 0.135 kg ha-1, nikosulfuron (Motivell) u količini 1.25 l ha-1, foramsulfuron (Equip) u količini 2.0 l ha-1, dikamba + rimsulfuron (Tarot plus) u količini 0.3 kg ha-1, mezotrion (Callisto) u količini 0.25 l ha-1 i tifensulfuron-metil (Grid) u količini 0.02 kg ha-1. Praćen je fitotoksičan efekat herbicida po EWRC skali od 1-9 i prinos zrna kukuruza. Linije kukuruza su pokazale različitu osetljivost u zavisnosti od primenjenog herbicida. Najnepovoljniji efekti u obe godine ispitivanja, za sve genotipove, su dobijeni na tretmanima Tarot plus i Grid, gde su utvrđene i najniže vrednosti prinosa zrna kukuruza.

The phytotoxic effect of herbicides on the maize grain yield was evaluated according to the 1-9 EWRC scale. Maize inbreds showed different susceptibility depending on the applied herbicide. The least favourable effects in both years for all genotypes were obtained in the treatments with Tarot plus and Grid, in which the lowest values of maize grain yield were recorded., U radu je ispitivana reakcija četiri samooplodne linije, roditeljskih komponenti ZP hibrida kukuruza na delovanje šest herbicida primenjenih posle nicanja kukuruza i korova (postemergence). U fazi 2-3 lista kukuruza primenjeni su sledeći herbicidi: izoksaflutol (Merlin 750-WG) u količini 0.135 kg ha-1, nikosulfuron (Motivell) u količini 1.25 l ha-1, foramsulfuron (Equip) u količini 2.0 l ha-1, dikamba + rimsulfuron (Tarot plus) u količini 0.3 kg ha-1, mezotrion (Callisto) u količini 0.25 l ha-1 i tifensulfuron-metil (Grid) u količini 0.02 kg ha-1. Praćen je fitotoksičan efekat herbicida po EWRC skali od 1-9 i prinos zrna kukuruza. Linije kukuruza su pokazale različitu osetljivost u zavisnosti od primenjenog herbicida. Najnepovoljniji efekti u obe godine ispitivanja, za sve genotipove, su dobijeni na tretmanima Tarot plus i Grid, gde su utvrđene i najniže vrednosti prinosa zrna kukuruza.",

AB  - Information on the effects of a certain cropping system on weed control and crop yields is necessary for an appropriate choice, adequate integration and timely application of various cropping practices into the system, which would provide the economic and ecologically safe production. Weediness can be controlled by growing maize hybrids in different densities, with the application of herbicides and irrigation as cropping practices. The combined employment of these practices is a part of the integrated weed management to whose successful application we have been aspiring for years. During the growing season in the period from 1996 to 1999, effects of irrigation and applied herbicides on the level of weed infestation and yield parameters of maize were studied. weed infestation was expressed through the number and the weight of weeds m-2. The plant height, leaf area, leaf area index and grain yield were observed in maize. weed infestation of maize differed depending on the application of both, irrigation and herbicides. The lowest, i.e. highest weed fresh weight was recorded under rainfed conditions and the application of herbicides (546.0 g m-2), i.e. on the untreated area under irrigation conditions (2573.1 g m-2), respectively. All investigated parameters of competitiveness and yielding of maize had statistically very significantly higher values under conditions of irrigation and the application of herbicides than under rainfed conditions without application of herbicides in all years of investigation.

AB  - Weed control in the seed maize production is facing some specific problems. Maize inbred lines are known to be susceptible to many stress factors, including actively growing weeds and some herbicides. The slower growth of maize inbreds, as well as, the open space between rows provide favourable conditions for emergence and growth of weeds during the whole growing season. Herbicide combinations applied in the seed maize production are the same as those applied in the commercial maize production, but, their efficiency is differently expressed in these crops. Environmental factors significantly affect weeds and maize development, as well as, herbicides affect maize inbred lines. The introduction of sulfonylurea herbicides, controlling grass weeds, has resulted in susceptibility of a greater number of maize inbred lines. Therefore, it was found that reaction of maize inbred lines gives a wide variability to sulfonilurea herbicides. Considering specificity of maize inbred lines, this study presents some problems in weed control in maize seed production.

AB  - Changes in pest populations occur on a regular basis and can be influenced by various biotic and abiotic factors, including human activites. The objective of this article was to outline several factors that contributed to the population changes in major maize pests over a 50 year period as reported in Serbian literature. Populations of economically important insects, pathogens and weeds were influenced by changes in agronomic practices and introduction of new species. Examples of new pests included: insect species such as western corn rootworm, weed species such as common ragweed and marshelder, and various pathogens including races of Exserohilum turcicum and Bipolaris zeicola. There was also an increase in maize dwarf mosaic virus and barley yellow dwarf virus.

AB  - The Nicosulfurone is post-emergence herbicide applied in maize crop. Studies were carried out under field conditions, pointed out to a different respond of inbreds to its effects. The tree inbreds were used. Plants were grown in a phytotrone up to the tree-leaf stage. The herbicide foliar application in the amount of 0.8 and 1.25 L ha-1 was done prior to the third leaf emergence. Seven days following the treatment plants were collected to the analysis. The following was measured: length and fresh and dry weight of the shoots and roots, chlorophyll content and cell wall peroxidase activity. Equal herbicide amounts differently affected examined inbreds, since the growth was either stimulated or inhibited. Both concentrations of Nicosulfurone reduced the total chlorophyll content in all three inbreds. Only in L2, as sensitive inbred, the growth of third leaf was inhibited and the peroxidase activity was the highest. In L1, as resistant inbred, the growth wasn't inhibited, with unchanged peroxidase activity; while in L3, as tolerant inbred, the leaf velocity was unchanged, with root growth stimulation and elevated peroxidase level (in treatment with higher herbicide concentration), regarding to inhibition of root growth, with lower peroxidase level (in treatment with lower herbicide concentration).
AB  - Nikosulfuron je herbicid koji se koristi posle nicanja kukuruza. Ispitivanja u poljskim uslovima su pokazala različitu reakciju linija na njegovo dejstvo. Biljke 3 linije kukuruza su gajene u fitotronu do faze trećeg lista. Pre njegove pojave tretirane su folijarno sa 0.8 i 1.25 L ha-1 Nikosulfurona. Sedam dana nakon tretmana merene su dužina i masa svežeg i suvog izdanka i korena, sadržaj hlorofila i aktivnost peroksidaze ćelijskog zida. Iste količine herbicida različito su delovale na ispitivane linije, te je došlo, kako do stimulacije, tako i do inhibicije rasta. Nikosulfuron je izazvao smanjenje sadržaja ukupnog hlorofila, kod sve tri linije, pri obe koncentracije. Samo je kod L2 (osetljive linije) došlo do inhibicije rasta trećeg lista, gde je i aktivnost peroksidaze bila najveća. Kod L1 (otporne linije) nije bila prisutna inhibicija rasta, uz nepromenjenu aktivnost peroksidaze; kod L3 (tolerantne linije) nije došlo do promene brzine rastenja listova, dok je bila zabeležena stimulacija rasta korena, uz veći nivo peroksidaze (pri većoj koncentraciji herbicida) i inhibicija rasta korena, uz niži nivo peroksidaze (pri nižoj koncentraciji herbicida).

abstract = "The Nicosulfurone is post-emergence herbicide applied in maize crop. Studies were carried out under field conditions, pointed out to a different respond of inbreds to its effects. The tree inbreds were used. Plants were grown in a phytotrone up to the tree-leaf stage. The herbicide foliar application in the amount of 0.8 and 1.25 L ha-1 was done prior to the third leaf emergence. Seven days following the treatment plants were collected to the analysis. The following was measured: length and fresh and dry weight of the shoots and roots, chlorophyll content and cell wall peroxidase activity. Equal herbicide amounts differently affected examined inbreds, since the growth was either stimulated or inhibited. Both concentrations of Nicosulfurone reduced the total chlorophyll content in all three inbreds. Only in L2, as sensitive inbred, the growth of third leaf was inhibited and the peroxidase activity was the highest. In L1, as resistant inbred, the growth wasn't inhibited, with unchanged peroxidase activity; while in L3, as tolerant inbred, the leaf velocity was unchanged, with root growth stimulation and elevated peroxidase level (in treatment with higher herbicide concentration), regarding to inhibition of root growth, with lower peroxidase level (in treatment with lower herbicide concentration)., Nikosulfuron je herbicid koji se koristi posle nicanja kukuruza. Ispitivanja u poljskim uslovima su pokazala različitu reakciju linija na njegovo dejstvo. Biljke 3 linije kukuruza su gajene u fitotronu do faze trećeg lista. Pre njegove pojave tretirane su folijarno sa 0.8 i 1.25 L ha-1 Nikosulfurona. Sedam dana nakon tretmana merene su dužina i masa svežeg i suvog izdanka i korena, sadržaj hlorofila i aktivnost peroksidaze ćelijskog zida. Iste količine herbicida različito su delovale na ispitivane linije, te je došlo, kako do stimulacije, tako i do inhibicije rasta. Nikosulfuron je izazvao smanjenje sadržaja ukupnog hlorofila, kod sve tri linije, pri obe koncentracije. Samo je kod L2 (osetljive linije) došlo do inhibicije rasta trećeg lista, gde je i aktivnost peroksidaze bila najveća. Kod L1 (otporne linije) nije bila prisutna inhibicija rasta, uz nepromenjenu aktivnost peroksidaze; kod L3 (tolerantne linije) nije došlo do promene brzine rastenja listova, dok je bila zabeležena stimulacija rasta korena, uz veći nivo peroksidaze (pri većoj koncentraciji herbicida) i inhibicija rasta korena, uz niži nivo peroksidaze (pri nižoj koncentraciji herbicida).",

AB  - The analysis of weed species in maize weed community, under conditions with and without herbicide application, in the location of Zemun Polje was performed during the maize vegetation season in 1996 and 1997. The floristic composition and structure of the weed community were estimated by the number of weed species and the number of their plants per area unit. According to the distribution of weed species and related number of their individuals, changes caused by the herbicide application were discussed. The biological spectrum of the weed community in each variant and a relative distribution of certain weed categories were analyzed. A significant increase of perennial weed species (42.13% on the average over two years) was observed in the variant with the herbicide application. Moreover, the number of weed species and the number of plants, determined in the variant of the herbicide application, were significantly lower than in the variant without the herbicide application. The obtained results indicate that the weed community in Zemun Polje has become of terophytic and geophytic characteristics with the prevalence of annual broad-leaved species and the increased distribution of grass and perennial, ruderal and resistant species.
AB  - Proučavana je zastupljenost vrsta korova u korovskoj zajednici kukuruza, u uslovima sa i bez primene herbicida, na lokaciji Zemun Polja. Tokom vegetacionog perioda kukuruza u 1996. i 1997. godini, sniman je floristički sastav i građa korovske zajednice utvrđivanjem broja vrsta i njihovih jedinki po jedinici površine. Na osnovu zastupljenosti vrsta korova i broja njihovih jedinki analizirane su promene nastale usled primene herbicida. Urađen je biološki spektar korovske zajednice na svakoj varijanti i analizirana relativna zastupljenost pojedinih grupa korova. Na varijanti sa primenom herbicida, uočeno je značajno povećanje učešća višegodišnjih vrsta korova (za 42,13% prosečno za dve godine). Na varijanti tretiranoj herbicidom je takođe utvrđeno značajno manje vrsta korova i njihovih jedinki u odnosu na varijantu bez primene herbicida. Dobijeni rezultati pokazuju da korovska zajednica kukuruza Zemun Polja dobija terofitsko-geofitski karakter sa dominacijom jednogodišnjih širokolisnih i povećanim učešćem travnih i višegodišnjih, ruderalnih i rezistentnih vrsta.

AB  - This study presents a brief survey of biological properties and the distribution of Ambrosia artemisiifolia L., an invasive and economically very important weed species. The distribution within the floristic composition and the structure of maize weed communities were analyzed. The trials were performed during the period 1995 to 2005. During 2002, a trial with herbicide combinations was set up with the aim to monitor a possibility of A. artemisiifolia suppression. A great number of weed plants was estimated per area unit in each trial variant. The distribution of the species, expressed by the number of plants, ranged from 0.4 to 29.3 plants m-2, depending on a year, or 5.1 plants m-2 on the average. Moreover, an average fresh weight of A. artemisiifolia amounted to 52.3 g m-2. The efficacy of observed herbicide combinations, applied after sowing and before weed emergence, and after maize emergence, in relation to both, the number of plants and the weed fresh weight, was over 90% during the whole growing period, except for certain cases. Even better results in control of this species were achieved by combining the herbicide application with other measures (maize growth density and irrigation). Considering each stated fact, all cultivation measures should be applied in suppression of the species A. artemisiifolia, in order to obtain results as good as possible. Therefore, it is primarily necessary to monitor, in an organized manner, a range of its distribution.

Ogled sa herbicidnim kombinacijama, u cilju suzbijanja A. artemisiifolia, postavljen je 2002. godine. Zakorovljenost se kretala od 0,4 do 29,3 jedinki po m2 (prosek 5,1 jedinki po m2). Prosečna sveža masa A. artemisiifolia je iznosila 52,3 g m-2. Efikasnost ispitivanih kombinacija, primenjenih posle setve, a pre i posle nicanja kukuruza, kako u odnosu na broj jedinki, tako i masu korova, bila je preko 90%. Kombinovanjem agrotehničkih mera, sa primenom herbicida, dobijeni su još bolji rezultati u suzbijanju. Potrebno je organizovano pratiti areal njenog rasprostranjenja i blagovremeno preduzimati odgovarajuće mere suzbijanja.

AB  - Effects of three sulfonylurea herbicides on 82 commercial maize inbreds, developed by the Maize Research Institute, Zemun Polje, were encompassed by the present study. Fifty six of the total number of inbreds were self-pollination ones derived in spatial isolation (PL), while the rest of 26 were inbred combinations (KL). The trial under production conditions was set up on degraded chernozem in Zemun Polje during 1997 and 1998. In 1997, the percentage of malformed plants was established for each inbred and each treatment. In 1998, phytotoxicity was determined only by the EWRC estimate. The highest percent of plants with leaf color change (45.63 %), occurring ten days upon the herbicide application (1st estimate), was observed in the treatment with rimsulfuron in 1997. The percent of injured plants in a sense of color change was on the average lower in inbred combinations (KL) than in PL inbred lines. The number of plants characterized by twisting and bending of the above ground parts was also on the average significantly lower. Injures of plants treated with primisulfuron-methyl, although the mildest, remained till the end of the growing season. The levels of phytotoxicity in PL inbreds, determined by the EWRC estimate, were higher in 1998 than 1997 and on the average ranged from 4.78 to 4.92, pointing out that plants were slightly to moderately injured.

Ogled je postavljen u proizvodnim uslovima, na zemljištu tipa degradirani černozem u Zemun Polju tokom 1997 i 1998. godine. U 1997. godini na svim varijantama ogleda utvrđivan je procenat deformisanih u odnosu na ukupan broj biljaka, za svaku liniju i svaki tretman. U 1998. godini korišćena je samo EWRC ocena fitotoksičnosti. Za svaki tretman obračunate su prosečne vrednosti dobijenih rezultata i odstupanje od proseka (SD). Simptomi oštećenja biljaka linija tretiranih sulfonilurea herbicidima ispoljavala su se u pojavi različitih simptoma, koji su se sastojali u promeni boje listova i pojavi uvrnuća nadzemnog dela. Promena boje nadzemnog dela se najčešće manifestovala u vidu crvene ili žute boje listova tretiranih biljaka. Kod osetljivih genotipova, intenzitet ovih promena je tako jak da dolazi do sušenja cele biljke. Najveći procenat biljaka sa promenom boje nadzemnog dela deset dana po primeni herbicida (prva ocena) uočen na tretmanu rimsulfuronom (45,63 %). Procenat oštećenja biljaka tipa promene boje kod kombinacija linija (KL) je u proseku manji u odnosu na samooplodne PL linije. Broj biljaka kod kojih su utvrđene deformacije tipa uvrnuća nadzemnog dela biljaka je u proseku bio znatno manji. Oštećenja biljaka tretiranih sa primisulfuron-metilom, iako najmanja, zadržavaju se do kraja vegetacionog perioda. Vrednosti EWRC ocena fitotoksičnosti kod PL linija u 1998. godini su veće u odnosu na 1997. godinu i u proseku su se kretale od 4,78 do 4,92. što ukazuje na to da su oštećenja biljaka laka do umerena. Rezultati ukazuju da postoji mogućnost primene sulfonilurea herbicida kod otpornih linija kukuruza. ččinjenica da je osetljivost linija u odnosu na herbicide u jakoj zavisnosti i od klimatskih uslova staništa, ukazuje na obaveznu opreznost pri primeni ovih herbicida u semenskoj proizvodnji ovog useva.

AB  - The two herbicides and their combined treatment influenced the change of water input in each of 15 investigated maize inbreds. The water volume (ml) fluctuated between 11 to 110% in shoot and 23 to 275% in root, what introduced the change of free energy (G) from -254.6 to -151.6 KJ in shoot and from -248.0 to -172.3 KJ in root. The difference in free, potential energy between non- and treatment (oΔtreatG) was in shoot from 11.1 to 90.2 KJ and in root from 16.8 to 75.7 KJ. Further, the lower magnitude of oΔtreatG amplitude between root and shoot implicated the tolerance of genotypes to applied herbicides. The energy, spent in biosynthesis of 1mg dry substance was amounted from 75.6 to 16.8 KJ mg-1; the applied herbicide treatments assembled the group of genotypes with lowered necessity of this energy, what has the positive implications in the sense of thermodynamics.

Energija, utrošena za sintezu 1 mg suve supstance je iznosila 75.6 do 16.8 KJ mg-1. Primenjeni herbicidi su istakli grupu genotipova koja je imala manje energetske potrebe za procese biosinteze, što predstavlja pozitivnu tendenciju, sa termodinamičke tačke gledišta.

AB  - From 15 maize inbreds, submitted to alachlor and atrazine treatment in controlled conditions, after 14 days growing in sand under distilled water, fresh and dry weight and length of root and shoot were determined. The parameters derived of those measurements: concentration (gL-1), root: shoot relation and pseudospecific density (d, d-1, µmol mg-1) classified the mechanisms of herbicide influence in whole plants and roots or shoots. Thus, alachlor lowered weights, lengths, root: shoot relation and elevated concentration in all inbreeds, underlining the suppression of water input and root as the target. The atrazine, on the contrary, downed concentration, promoting the water-induced growth. The applications of diluted or combined herbicides’ forms segregated the genotypes to tolerant or sensitive as whole plant or partially root or shoot, only. The pseudo-specific density separated the genotypes to non- or stable system to hold up the induced change.
AB  - Klijanci 15 samooplodnih linija kukuruza bili su izloženi tretmanu alahlora i atrazina, u kontrolisanim uslovima klijališta (gajeni su 14 dana na peščanoj podlozi, uz zalivanje sa destilovanom vodom). Bila su izvršena merenja sveže i suve mase, dužine korena i izdanka. Dobijeni parametri su poslužili za izračunavanje: koncentracije (gL-1), koren: izdanak relacije i pseudospecifične gustine (d, d-1, µmol mg-1). Navedene veličine su primenjene za definisanje uticaja herbicida, kako na cele klijance, tako i na njihove pojedine delove: koren i izdanak. Tako je alahlor uticao na smanjenje sveže i suve mase, dužine i relacije korena i izdanka, uz povećanje koncentracije, kod svih linija. Potrebno je naglasiti i smanjenu apsorpciju vode u koren, kao mesto sa najintenzivnijom reakcijom na alahlor. Sa druge strane, atrazin je smanjio koncentraciju, vodeći tzv. vodom indukovanom porastu.

AB  - Effects of crop density and herbicide application on distribution of weed species within maize weed community in the location of Zemun Polje were studied. During the maize growing season in 1996 and 1997, floristic composition and structure of weed community were surveyed. Furthermore, number of species, number of plants per species and fresh weight of all weeds per area unit over all densities in both, treated and nontreated variants, were also determined. Changes, occurring under effects of higher maize crop densities and herbicide application, were analyzed on the basis of distributed weed species and their plants per species. Moreover, relative distribution of certain weed groups was determined. Significant effects of crop density x herbicide application interaction were observed in reduction of relative distribution of certain broad leafed and perennial weeds within total maize weediness at Zemun Polje.

AB  - The floristic composition and structure of the maize weed community was analyzed under conditions of higher crop densities and two-year climatic conditions. The studies were carried out on degraded chernozem at Zemun Polje in 1996 and 2004. The effect of maize density on the floristic composition, fresh and dry weight of weeds was observed over years. There were seven variants of the crop density: Gr 40,816, G2-50,124, G3-59,523 G4-69,686, G5-79,365, G6-89,286 and G7-98,522. Herbicides were applied. Weed sampling was done by the one square meter area method during the summer period. The number of plants per species was determined in each trial variant and also fresh weight of each species was measured per area unit and on the basis of it, the total fresh and dry weight of all weed species was calculated. At the end of the growing period, the hybrid yields were recorded and the means are presented in this paper. A total of 18 weed species were detected in maize weed community at Zemun Polje under conditions of the herbicide application. In 1996, the species Convolvulus arvensis (7.6 plants m~2), Sorghum halepense (5.1 plants m~2) and Solarium nigrum (4.6 plants m"2) prevailed, while in 2004, Solanum nigrum (44.6 plants m"2) was the most distributed species. The higher maize crop density was, the lower number of weed plants per species and total weed weight were over both years. The analysis of weed fresh weight in the density x year interaction showed the statistically significant differences. Obtained results point out to the fact that the choice of the appropriate growing density for each hybrid leads to higher yields and it significantly affects weediness of the given crop, which is another contribution of this measure to weed control.
AB  - Analiziran je floristički sastav i građa korovske zajednice kukuruza u uslovima povećane gustine kukuruza u klimatskim uslovima dve godine. Ispitivanja su obavljena na zemljištu tipa degradirani černozem u Zemun Polju u 1996. i 2004. godini. Praćen je uticaj gustine kukuruza na floristički sastav, svežu i suvu masu korova u zavisnosti od godine. Gustina useva je bila zastupljena sa sedam varijanti Gi-40.816; G2-50.124 G3-59.523; G4-69.686; G5-79.365; G6-89.286 i G7-98.522. Ispitivanja su izvedena u uslovima primene herbicida. Uzimanje uzoraka korova vršeno je metodom probnih kvadrata u letnjem periodu. Na svakoj varijanti ogleda određivan je broj jedinki i merena je sveža masa svake vrste po jedinici površine, na osnovu čega je izračunata ukupna sveža i suva masa svih vrsta korova. Na kraju vegetacije meren je prinos hibrida, a u radu su prikazane prosečne vrednosti. U korovskoj zajednici kukuruza Zemun Polja u uslovima primene herbicida registrovano je 18 vrsta korova. Najzastupljenije vrste u 1996. godini su bile Convolvulus arvensis (7,6), Sorghum halepense (5,1) i Solarium nigrum (4,6) jedinki m~2, a u 2004. Solarium nigrum (44,6) jedinki m"2. Sa povećanjem gustine useva kukuruza smanjuje se broj jedinki i ukupna suva masa korova u obe godine. Analizom sveže mase korova u interakciji gustina x godina dobijene su statistički značajne razlike. Dobijeni rezultati ukazuju da izborom odgovarajuće gustine gajenja za svaki hibrid pored povoljnih uslova na prinos, može značajno da se utiče i na stanje zakorovljenosti datog useva, što ide u prilog primeni ove mere u kontroli korova.

AB  - The effect of nicosulfuron application timing on weeds and sweet maize hybrid (ZPSC 504su) was studied. The herbicide was applied according to the recommended rate for commercial maize on four dates of applications. Weed plants abundance (the number of species, the number of plants per species and fresh biomass) was evaluated for each weed species for each herbicide application date, and at the end, the total dry weight of weeds per a variant was estimated. The herbicide application on all four dates over both years reduced the number of weed species and the number of weed plants per species. Effects of the applied herbicide differed over years due to differences in meteorological conditions. The ear length of the studied sweet maize hybrid statistically significantly differed in the herbicide application date and investigation year interaction. Weed suppression with the aim to obtain the planned yields of sweet maize has an important role. Nevertheless, different susceptibility of sweet maize to herbicides points out to cautiousness in their application.
AB  - Ispitivan je uticaj vremenskih rokova primene nikosulfurona na korove i hibrid kukuruza šećerca (ZPSC 504su). Herbicid je primenjen u preporučenoj količini (500 g a.m. ha-1) za merkantilni kukuruz, u četiri vremenska roka primene herbicida (V.R). Kod korova je ocenjivana brojna zastupljenost (broj vrsta, broj jedinki i sveza masa) svake vrste korova u svakom vremenskom roku primene herbicida, a na kraju obračunata ukupna suva masa korova po varijanti. Kod kukuruza je u 1997. godini merena sveza biomasa celih biljaka kukuruza, s dužina i težina klipova ispitivanog hibrida kukuruza šećerca u vreme tehnološke zrelosti merena je u obe godine. Dobijeni rezultati su statistički obrađeni metodom analize varijanse i analizirani LSD testom. Primena herbicida u sva četiri vremenska roka, u obe godine, uticala je na smanjenje broja vrsta i jedinki korova. Međutim, zbog razlika u meteorološkim uslovima godina, efekat primenjenog herbicida na korove nije bio isti u obe godine. Biomasa kukuruza se u 1997. godini statistički značajno razlikovala u zavisnosti od vremena primene herbicida, pri čemu se i suva masa korova smanjivala. Dužina klipa ispitivanog hibrida šećerca se statistički značajno razlikovala u interakciji faktora vremenski rok primene herbicida i godine ispitivanja. Težina klipova kukuruza šećerca u fazi tehnološke zrelosti je u prošeku za obe godine značajno manja na kontroli. Dobijeni rezultati ukazuju na činjenicu da suzbijanje korova u postizanju planiranih prinosa kukuruza šećerca ima važnu ulogu. Ako se pri tome ima u vidu variranje klimatskih uslova, onda je pravovremena primena herbicida veoma važna. Pri svemu tome različita osetljivost kukuruza šećerca prema herbicidima ukazuje na opreznost pri njihovoj primeni.

AB  - Field bindweed is a perennial herb with rhizomes belonging to the family of twining plants (Convolvulaceae). It propagates from the seed or vegetatively (from buds formed in the root whose cuttings have a great capacity of regeneration). Field bindweed is distributed all over the world. Due to its dual propagation this plant is classified into a group of very noxious and resistant weeds. As herbicides are not powerful enough in this weed control it is recommended to apply combined chemical and mechanical measures. The present study analyses the effect of primary tillage, crop rotation and crop density on the distribution of this weed species in the maize crop. Satisfactory results in the improvement of the crop status and this perennial species control can be achieved within the integrated weed management system, which means a particular field cropping system.
AB  - Poponac njivski (C. arvensis L.) je višegodišnja zeljasta biljka sa rizomima. Pripada familiji povijuša (Convolvulaceae). Razmnožava se semenom i vegetativno (pupoljcima obrazovanim na korenu, čije reznice imaju veliku moć regeneracije). Rasprostranjena je u celom svetu. Dvostruki način razmnožavanja poponca svrstava ovu vrstu u veoma štetne i otporne korove. Kako se slabije suzbija herbicidima, preporučuje se kombinovana primena hemijskih i mehaničkih mera. U radu se analizira uticaj osnovne obrade zemljišta, plodoreda i gustine useva na zastupljenost ove vrste u usevu kukuruza. U okviru integralnog sistema kontrole korova, koji podrazumeva određeni sistem gajenja useva, mogu se postići zadovoljavajući rezultati u poboljšanju stanja useva i kontroli ove višegodišnje vrste.
