AB  - World population is growing exponentially and agricultural production must meet the needs of the food. An attractive strategy for increasing productivity per unit area of land available is to intensify land use. Given that this strategy creates a number of problems in terms of the environment and yet can not meet the food needs of humanity on planet Earth, must be found alternative approaches to growing plants. One of them is intercropping - growing two or more crops in the same space at the same time. This system leads to an increase in productivity per unit area of land through better use of resources, to reduce the risk, reduce competition from weeds and leads to the stabilization of yields. Several important factors affecting the development of this system as well as a selection of compatible crops, vegetation length crop density and time of sowing/planting, as well as socio-economic status of farmers and regions. As a numeric indicator of efficient use of land commonly used land equivalent ratio index (LER) and on the basis of this index have shown the advantages of growing intercrops. Cereals grown merged with legumes are the best and most widely practiced types of intercrops, wheat and within the most important place belong to the maize. Precisely, in this study will be based on a review of papers that deal with the issue of growing maize intercropping system with other crop species.
AB  - Svetska populacija raste eksponencijalno a poljoprivredna proizvodnja mora da zadovolji potrebama u hrani. Atraktivna strategija za povećanje produktivnosti po jedinici površine raspoloživog zemljišta je da se intenzivira korišćenje zemljišta. S obzirom da takva strategija prouzrokuje brojne probleme u pogledu životne sredine a opet ne može da zadovolji potrebe za hranom čovečanstva na planeti Zemlji, moraju se iznalaziti alternativni pristupi u gajenju biljaka. Jedan od njih je združivanje useva (intercropping) - gajenje dva ili više useva u istom prostoru u isto vreme. Ovaj sistem dovodi do povećanja produktivnosti po jedinici površine zemljišta putem boljeg korišćenja resursa, do smanjenja rizika, smanjenja konkurencije od strane korova i dovodi do stabilizovanja prinosa. Nekoliko značajnih faktora utice na razvoj ovog sistema kao što su izbor kompatibilnih useva, dužin vegetacionog perioda useva, gustine i vreme setve/sadnje, kao i socio-ekonomski status poljoprivrednih proizvođača i regiona. Kao brojčani pokazatelj efikasnijeg korišćenja zemljišta najčešće se koristi indeks efikasnosti korišćenja zemljišta (LER) i na osnovu ovog indeksa dokazane su prednosti gajenja združenih useva. Žita gajena združeno sa leguminozama su najpovoljnije i najčešće praktikovane vrste združenih useva, a u okviru žita najznačajnije mesto pripada kukuruzu. Upravo, u ovoj studiji ćemo se bazirati na pregledu radova koje tretiraju problematiku gajenja kukuruza u združenim usevima sa drugim ratarskim vrstama.

AB  - Rotation is a cropping system that has many advantages and ensures better crop growth and yielding. Its combination with other cropping measures can ensure optimal crop density for maximal growth and photosynthesis efficiency. The aim of this study was to investigate the influence of different cropping systems: monoculture and two rotations, including maize, wheat and soybean (MSW and MWS), and different weed management methods (weed removal by hoeing, application of a full recommended herbicide dose (RD) and half that dose (0.5 RD), and weedy check) on weed biomass and maize growth parameters - leaf area index (LAI), free energy, contents of chlorophyll and carotenoids, grain yield, and their possible relationships in two fields of the maize hybrids ZP 677 (H1) and ZP 606 (H2). The lowest LAI and grain yield were found in monoculture, particularly in weedy check, which had relatively high weed infestation. Higher weed biomass was also observed in herbicide treated plots in monoculture. Such high competition pressure indicates a stress reflected on reduced LAI and chlorophyll content, and increased free energy and content of carotenoids. On the other hand, rotation, particularly if it is combined with the application of herbicides or hoeing, had a positive impact on yielding potential by increasing LAI and the contents of chlorophyll and carotenoids, and decreasing free energy.
AB  - Plodored, kao sistem gajenja ima brojne prednosti koje se ogledaju u boljem rastu i prinosu useva. Njegovom kombinacijom sa drugim merama gajenja moguće je obezbediti optimalnu gustinu za maksimalan rast i efikasnost fotosinteze. Cilj ovog rada je da se ispita uticaj različitih sistema gajenja: monokulture i dva tipa rotacija koja uključuju kukuruz, pšenicu i soju (MSW i MWS), zajedno sa različitim merama kontrole zakorovljenosti (okopavanje, upotreba preporučene (RD), polovine preporučene (0,5 RD) doze herbicida i kontrola bez uklanjanja korova) na biomasu korova, parametre rasta kukuruza - indeks lisne površine (LAI), slobodnu energiju, sadržaj hlorofila i karotenoida, prinos zrna, kao i njihove međusobne odnose kod dva hibrida kukuruza: ZP 677 (H1) i ZP 606 (H2)). Najniži LAI i prinos zrna bili su ostvareni u monokulturi, posebno u kontroli, zajedno sa relativno visokom zakorovljenošću. Veća biomasa korova je bila u tretmanima sa herbicidima u monokulturi. Ovakva situacija bi mogla da ukaže na prisustvo stresa koji se odražava na smanjenje LAI i sadržaja hlorofila, kao i povećanje vrednosti slobodne energije i karotenoida. Sa druge strane, plodored, posebno u kombinaciji sa herbicidima ili okopavanjem ispoljio je pozitivan uticaj na prinos preko povećanja LAI, sadržaja hlorofila i karotenoida i smanjenja slobodne energije.

AB  - Intercropping systems could improve utilization of the most important resources (soil, water and nutrients), provide a better control of weeds, pests and diseases, and finally higher productivity, especially under rain-fed growing conditions. This study aimed to determine the effects of three maize (Zea mays L.) prolific hybrids (FAO 500, 600 and 700) and the spatial intercrop patterns on the above-ground biomass and grain yields of maize and soybean (Glycine max L. Merrill), on chernozem soil type at Zemun Polje, Belgrade, in 2003, 2004 and 2005. The experimental design was a complete randomized block with four replications and three treatments: 3 rows of maize and 3 rows of soybean in strips for each maize hybrid (three variants, 3 rows of maize and 3 rows of soybean in alternate rows for each hybrid (another three variants) and monocrops of both maize and soybeans. To optimize the ecological and economic benefits of maize/soybean intercrop in terms of yield, variety selection and compatibility of the component crops should be made using established agronomic management practices involving the two crops. Suitable maize varieties for maize/soybean intercrop systems are varieties that have less dense canopy. These varieties would therefore have lesser shading effect to the understory beans. However, establishment of an appropriate spatial arrangement of the component crops would be essential to alleviate negative effects especially on the less competitive crop. The intercropping system in alternate rows showed significantly higher above-ground biomass and grain yields in comparation with both the strip intercropping system and maize monocrops in 2004. Soybean gave significantly lower above-ground biomass and grain yield in intercrops than in monocrops. Maize prolific hybrid growing in intercropping with soybean as legume crop, increased productivity of cropping system, especially in favourable agroecological conditions. Maize and soybean yields reduction could have also been due to inter-specific competition for resources such as nutrients and water. Moreover, performance of the currently grown varieties in the semi-arid regions depends on the amount of rainfall received during the growing season.
AB  - Gajenjem združenih useva može se poboljšati iskorišćenost najvažnijih resursa (zemljišta, vode i hranljivih materija), obezbediti bolja kontrola korova, štetočina i bolesti, i povećati produktivnost, posebno u uslovima prirodnog vodnog režima. Cilj ovih istraživanja jeste da se utvrde uticaji tri različita višeklipa hibrida kukuruza (FAO 500, 600 i 700) i prostornog rasporeda (naizmenični redovi i trake) na prinose nadzemne biomase i zrna združenih i čistih useva kukuruza i soje. Istraživanja su obavljena na zemljištu tipa černozem u Zemun Polju, Beograd, tokom 2003, 2004 i 2005. godine. Ogledi su izvedeni po planu potpuno slučajnog blok sistema u četiri ponavljanja i tri tretmana: združeni usev kukuruza i soje u trakama za svaki hibrid kukuruza (tri varijante), združeni usev kukuruza i soje u naizmeničnim redovima za svaki hibrid (još tri varijante) i čisti usevi kukuruza i soje. U združenom usevu u naizmeničnim redovima su dobijeni značajno veći prinosi nadzemne biomase i zrna kukuruza. Ispitivani višeklipi hibridi kukuruza iz različitih FAO grupa zrenja, gajeni u združenom usevu sa sojom, imali su pozitivan uticaj na prinos, kako nadzemne biomase, tako i zrna, ali samo u 2004. godini koja je ocenjena kao najpovoljnija sa stanovišta meteoroloških uslova, posebno količine i rasporeda padavina.

AB  - Intercropping two or more crops under similar micro environmental conditions can increase the agricultural productivity. A field study was conducted in three-year period 2003-2005 at experimental field of Maize Research Institute, Belgrade on chernozem soil type. This examination included three experimental hybrids of maize from various FAO groups of ripening (500,600 and 700) and the type of soya bean from II group of ripening (Nena). Maize and soybean was grown in pure stands and three combinations of intercrops (alternate-row and in strip intercropping). Additive design was used for creating of intercrop variants. The paper investigated the grain yield of maize and soya bean in the intercropping, and compared with the yield of the monocrops. Comparison of the yield was carried out with the most Number indicators- Land equivalent Ratio index (LER). For individual comparisons used the standard error differences between means. Comparing with the intercropping production of monocrops production of maize and soya bean, with the index LER, the results obtained indicate that there are more intercropping production, especially in 2004. The three-year average, the increase of grain yield in the intercropping in relation to monocrops of maize and soya bean was 45% in the strip, or 49% in the alternate rows. Intra-species the intensity of competition is higher in the strip and in the pattern arrangement of the resulting lower relative grain yield, primarily due to lower maize yield.

A field study was conducted in three-year period 2003-2005 at experimental field of Maize Research Institute, Belgrade on chernozem soil type. This examination included three experimental hybrids of maize from various FAO groups of ripening (500,600 and 700) and the type of soya bean from II group of ripening (Nena). Maize and soybean was grown in pure stands and three combinations of intercrops (alternate-row and in strip intercropping). Additive design was used for creating of intercrop variants.

AB  - Decrease in the number and biomass of weeds, especially of perennial ones, is one of the advantages of intercropping. The results obtained in the first two years of investigation (2003 and 2004) show that the number of perennial weeds and their fresh weight were lower in both plant arrangement patterns in intercrops than in maize and soybean monocrops. However, in 2005, the arrangement pattern in strips was the only efficient pattern in terms of weed fresh weight per area unit. In the dry year of 2003, the plant arrangement pattern in alternate rows was advantageous, while the pattern in strips was more efficient in 2004 and 2005. Intercropping affected maize more favourably than soybean crops, in which the positive effect was most evident in 2005, especially in strips, and it mainly related to the number of weed plants per species. The longer the growing season of studied maize hybrids was, the less intensive was weed distribution in monocrops. Such a regularity was expressed in intercrops in 2003 in both plant arrangement patterns, while in 2004 and 2005 intercropping in strips was efficient with late maturity hybrids, especially in relation to weed fresh weight.
AB  - Jedna od prednosti združivanja useva jeste smanjenje broja i mase korova, naročito višegodišnjih. U prve dve godine ispitivanja (2003. i 2004), broj višegodišnjih korova i sveža masa korova bila je manja u oba prostorna rasporeda u združenim u odnosu na čiste useve kukuruza i soje. Međutim, u 2005. godini, samo je prostorni raspored u trakama ispoljio efikasnost u pogledu sveže mase korova po jedinici površine. U sušnoj, 2003. godini, prednost je bila na strani združivanja u naizmeničnim redovima, a u 2004. i 2005. godini, veću efikasnost je ispoljio drugi prostorni raspored - trake. Združivanje useva je povoljnije delovalo na kukuruz, dok je kod useva soje pozitivan efekat združivanja najuočljiviji u 2005. godini, posebno u trakama, a uglavnom se odnosi na broj jedinki korova. Zakorovljenost čistih useva kukuruza se smanjivala sa povećanjem dužine vegetacionog perioda ispitivanih hibrida kukuruza. U združenim usevima takva pravilnost je ispoljena u 2003. godini, u oba prostorna rasporeda, dok je u 2004. i 2005. godini, združivanje u trakama sa kasnostasnijim hibridima kukuruza ispoljilo efikasnost, posebno u pogledu sveže mase korova.

AB  - Weeds have been a limiting factor in agriculture since the beginning of its development. With the intensive cultivation of certain corps, weeds, due to their great adaptability, have evolved to be more or less resistant to common systems of suppression. This weed resistance has lead to the increased use of herbicides, which furthermore has increased the total production costs and risks to the environment and human health. Therefore, other, alternative measures for weed suppression should be applied. Weed control measures are one of the natural ways of solving problems related to crop weediness, which can be achieved by special systems of cropping in which intercrops have an important role. The aim of this study was to determine the effects of different maize hybrids and spatial maize-soybean intercrop patterns on the floristic composition of the weed community in spring. The trial was carried out according to the additive intercropping system under rainfed conditions in the experimental filed of the Maize Research Institute, Zemun Polje on chernozem in 2003 and 2004. The weed community in the maize-soybean intercrop consisted of 15 weed species during the two-year studies. Solanum nigrum (L.) and Amaranthus retroflexus (L.) were dominant annual weed species, while Sorghum halepense (L.) Pers. prevailed among perennial weed species. The greatest, i.e. lowest number and weight of weed species were measured in monocrops, i.e. in maize-soybean intercrop sown in alternate rows (29.3 m-2), respectively.

AB  - Due to the absolute dominance of maize in a sowing structure of the arable areas, maize continuous cropping is still very frequent. It is followed by a two-crop rotation (winter wheat-maize), and then by a very favorable, ever more presented, three-crop rotation (winter wheat-maize-soybean). Nevertheless, maize continuous cropping is considered questionable due to an occurrence of a dangerous pest - western corn rootworm (Diabrotica virgifera virgifera La Conte), which is for now efficiently suppressed only by the crop rotation. This objective of this study was to observe effects of the two- and three-crop rotation on the grain yield in comparison with continuous cropping of winter wheat and maize during the period 2000-2004. Winter wheat and maize were grown on leached chernozem under rainfed conditions. The analysis of variance of the winter wheat and maize yield shows significant differences over years of investigation. The highest (4.30 t ha-1), i.e. lowest (3.70 t ha-1) yield of winter wheat in continuous cropping was obtained in 2001 and dry 2003, respectively. Winter wheat grain yield in the two-crop rotation (4.10 t ha-1) and the three- crop rotation (4.11 t ha-1) was statistically very significantly higher than the grain yield recorded in continuous cropping (3.70 t ha-1). Maize grain yield in continuous cropping (6.89 t ha-1) in the investigation period was statistically very significantly lower than the grain yield in the two-crop rotation (7.44 t ha-1) and the three-crop rotation (7.61 t ha-1).
AB  - Zbog apsolutne dominacije kukuruza na oraničnim površinama u setvenoj strukturi, monokultura kukuruza, je i dalje jako česta pojava. Na drugom mestu je dvopoljni plodored (ozima pšenica - kukuruz), a ono što je vrlo pozitivno je sve zastupljeniji tropoljni plodored, u čiji sastav ulazi i soja. Monokultura kukuruza je dobrim delom dovedena u pitanje, prvenstveno zbog pojave opasne štetočine - kukuruzove zlatice (Diabrotica virgifera virgifera La Conte) jer jedina prava i efikasna mera za suzbijanje ove vrste, za sada, je plodored. U ovom radu je ispitivan uticaj gajenja pšenice i kukuruza u dvopoljnom i tropoljnom plodoredu u odnosu na prinos ovih useva u monokulturi, u periodu od 2000 do 2005. Tip zemljišta na kome su gajeni ovi usevi, u uslovima prirodnog vodnog režima, je izluženi černozem. Na osnovu statističke analize dobijenih rezultata, došlo se do zaključka da su prinosi ozime pšenice i kukuruza u ispitivanim godinama bili statistički značajno različiti. Najviši prinos ozime pšenice u monokulturi dobijen je u 2001. godini (4,30 t/ha), a najniži u sušnoj 2003. godini (2,90 t/ha). Dobijeni prosečni prinosi zrna pšenice u dvopoljnom (4,15 t/ha) i tropoljnom plodoredu (4,19 t/ha) su se statistički vrlo značajno razlikovali od prinosa ostvarenog gajenjem ovog useva u monokulturi (3,77 t/ha). Prosečan prinos zrna kukuruza u monokulturi za period istraživanja (6,94 t/ha) je bio statistički vrlo značajno niži u odnosu na prinos dobijen u dvopoljnom (7,73 t/ha) i tropoljnom (8,11 t/ha).

abstract = "Due to the absolute dominance of maize in a sowing structure of the arable areas, maize continuous cropping is still very frequent. It is followed by a two-crop rotation (winter wheat-maize), and then by a very favorable, ever more presented, three-crop rotation (winter wheat-maize-soybean). Nevertheless, maize continuous cropping is considered questionable due to an occurrence of a dangerous pest - western corn rootworm (Diabrotica virgifera virgifera La Conte), which is for now efficiently suppressed only by the crop rotation. This objective of this study was to observe effects of the two- and three-crop rotation on the grain yield in comparison with continuous cropping of winter wheat and maize during the period 2000-2004. Winter wheat and maize were grown on leached chernozem under rainfed conditions. The analysis of variance of the winter wheat and maize yield shows significant differences over years of investigation. The highest (4.30 t ha-1), i.e. lowest (3.70 t ha-1) yield of winter wheat in continuous cropping was obtained in 2001 and dry 2003, respectively. Winter wheat grain yield in the two-crop rotation (4.10 t ha-1) and the three- crop rotation (4.11 t ha-1) was statistically very significantly higher than the grain yield recorded in continuous cropping (3.70 t ha-1). Maize grain yield in continuous cropping (6.89 t ha-1) in the investigation period was statistically very significantly lower than the grain yield in the two-crop rotation (7.44 t ha-1) and the three-crop rotation (7.61 t ha-1)., Zbog apsolutne dominacije kukuruza na oraničnim površinama u setvenoj strukturi, monokultura kukuruza, je i dalje jako česta pojava. Na drugom mestu je dvopoljni plodored (ozima pšenica - kukuruz), a ono što je vrlo pozitivno je sve zastupljeniji tropoljni plodored, u čiji sastav ulazi i soja. Monokultura kukuruza je dobrim delom dovedena u pitanje, prvenstveno zbog pojave opasne štetočine - kukuruzove zlatice (Diabrotica virgifera virgifera La Conte) jer jedina prava i efikasna mera za suzbijanje ove vrste, za sada, je plodored. U ovom radu je ispitivan uticaj gajenja pšenice i kukuruza u dvopoljnom i tropoljnom plodoredu u odnosu na prinos ovih useva u monokulturi, u periodu od 2000 do 2005. Tip zemljišta na kome su gajeni ovi usevi, u uslovima prirodnog vodnog režima, je izluženi černozem. Na osnovu statističke analize dobijenih rezultata, došlo se do zaključka da su prinosi ozime pšenice i kukuruza u ispitivanim godinama bili statistički značajno različiti. Najviši prinos ozime pšenice u monokulturi dobijen je u 2001. godini (4,30 t/ha), a najniži u sušnoj 2003. godini (2,90 t/ha). Dobijeni prosečni prinosi zrna pšenice u dvopoljnom (4,15 t/ha) i tropoljnom plodoredu (4,19 t/ha) su se statistički vrlo značajno razlikovali od prinosa ostvarenog gajenjem ovog useva u monokulturi (3,77 t/ha). Prosečan prinos zrna kukuruza u monokulturi za period istraživanja (6,94 t/ha) je bio statistički vrlo značajno niži u odnosu na prinos dobijen u dvopoljnom (7,73 t/ha) i tropoljnom (8,11 t/ha).",

AB  - In recent times little attention has been paid to the crop rotation, as a system of utilization of the arable land under different crops (mainly annual ones). Reasons for the introduction of the crop rotation are numerous, and they are classified into biological, agro technical and organizational-economical ones. According to various research works in the World there are evidences that a proper crop rotation can solve about 70% problems related to pests and diseases. This paper deals with effects of the three- and four-crop rotation on the grain yield compared with winter wheat continuous cropping. Grain yields were recorded in the regular crop rotation experiment set up in the experimental field "Radmilovac" of the Faculty of Agriculture, during the period of 2000-2004. In the three-crop rotation variant following crops were maize, soybean and winter wheat. The four-crop rotation encompassed maize, winter wheat, red clover and spring barley + red clover. The winter wheat cultivars Pobeda grown under rainfed conditions on leached chernozem was studied. The analysis of variance of the winter wheat yield showed significant differences among years of investigation. The highest yield of winter wheat (4.53 t ha"1) was obtained in 2001, while the lowest one (3.05 t ha"1) was recorded in dry 2003. Grain yield of winter wheat in continuous cropping (3.70 t ha"1) was statistically very significantly lower than grain yield in the three- (4.11 t ha"1) and four-crop rotation (4.07 t ha"1), while difference in grain yield between the three- and the four-crop rotation variants was no statistically significant.
AB  - Plodoredu kao sistemu korišćenja obradivih površina gajenjem različitih useva (uglavnom jednogodišnjih) se u poslednje vreme pridaje mali značaj. Razlozi za uvođenje plodoreda su brojni, a dele se na biološke, agrotehničke i organizaciono-ekonomske. Prema mnogim istraživanjima u svetu došlo se do zaključka da se pravilnim plodoredom može rešiti oko 70 % problema koji se odnose na bolesti i štetočine u ratarstvu. U ovom radu je ispitivan uticaj gajenja pšenice u tropoljnom i četvoropoljnom plodoredu na prinos u odnosu na gajenje pšenice u monokulturi. Prinosi su mereni u okviru redovnih plodorednih polja na oglednom školskom dobru Poljoprivrednog fakulteta (Radmilovcu) u 2000,2001,2002,2003. i 2004. godini. U tropoljnom plodoredu zastupljeni su kukuruz, soja i ozima pšenica, a u červoropoljnom plodoredu kukuruz, ozima pšenica, crvena detelina i jari ječam+crvena detelina.

AB  - A joint effect of four cropping practices (irrigation, crop density, hybrid and herbicide application) on maize weed infestation, expressed by fresh mass of weeds (g m-2), was monitored in a four year period (1996-1999). Fresh mass of weeds was higher on the average for all years in the area under irrigation than in the area under rainfed conditions and it statistically significantly decreased under increased crop densities. Fresh mass of weeds was significantly higher in the control than in the herbicide treated variant. The increased crop density and herbicide application interaction affected fresh mass of weeds in such a way that it was the lowest in the highest density in the treated variant almost in each year of investigation. In addition, fresh mass of weeds was affected by the herbicide application and maize hybrid interaction.
AB  - U četvorogodišnjem periodu 1996-1999. godine ispitivan je uticaj kombinovane primene četiri mere gajenja (navodnjavanja, gustine useva, hibrida i primene herbicida) na zakorovljenost kukuruza, izraženu kroz svežu masu korova (g m-2). Sveža masa korova je, prosečno za sve godine, bila veća na površini u navodnjavanju i statistički se značajno smanjivala sa povećanjem gustine gajenja. Sveža masa korova je bila statistički vrlo značajno veća na kontrolnoj u odnosu na herbicidima tretiranu varijantu. Ukupna sveža masa korova, u uslovima prirodnog vodnog režima, bila je veća u hibridu ZPSC 704, a u uslovima navodnjavanja u hibridu ZPSC 42A. Povećana gustina gajenja i primena herbicida u interakciji su uticale da sveža masa korova bude najmanja u najvećoj gustini, na tretiranoj varijanti skoro u svim godinama ispitivanja. Na svežu masu korova, uticala je i interakcija primene herbicida sa hibridom kukuruza. Dobijeni rezultati idu u prilog pretpostavci da se, i u našim uslovima, primenom vise mera kao delà integralnog sistema, uz primenu herbicida, mogu uspešno suzbijati korovi u kukuruzu.
