AB  - Intercropping, as a combination of different crops at the same time and the same field, enables interaction of their roots, improving plant growth and stress tolerance, thus improving nutritional quality of produced grains. The investigation was aimed to examine the effect of different cropping systems: intercropping in combination with alternating rows and alternating strips of maize and soybean, as well as single cropping, combined with different fertilization regimes (conventional, application of organic fertilizer, bio-fertilizer and control) on the antioxidant content (glutathione [GSH], phenolics and yellow pigment [YP]) in red maize and black soybean grain. Black soybean is richer in antioxidants than red maize. Season expressed the highest influence on the level of GSH, phenolics and YP in maize and soybean, while cropping system and fertilization regime influenced GSH and phenolics. The antioxidant level in grains with greater weight corresponded with an increased GSH level for maize, as well as an increased GSH and phenolic level for soybean, while smaller grains were characterised by the increased YP content. Generally, antioxidant content was increased mainly by alternating strips in maize grain and by alternating rows in soybean grain. Bio-fertilizer had the highest impact on an increase in GSH in maize grain and YP in soybean grain, while organic fertilizer was important for acquiring of GSH and phenolics in soybean grain.
AB  - Združeni usev, kao kombinacija različitih useva, koji se gaje u isto vreme i na istom polju, omogućava interakciju njihovih korenova, poboljšava rast i tolerantnost na stres, poboljšavajući tako nutritivni kvalitet proizvedenog zrna. Cilj istraživanja je bio da se ispita efekat različitih sistema gajenja: združeni usev kombinujući naizmenične redove i naizmenične trake kukuruza i soje, kao i pojedinačne useve, zajedno sa različitim režimima đubrenja (konvencionalni, upotreba organskog đubriva, bio-đubriva i kontrola) na sadržaj antioksidanta (glutationa [GSH], fenola i žutog pigmenta [YP]) u zrnu crvenog kukuruza i crne soje. Zrno crne soje je bogatije antioksidantima od crvenog kukuruza. Sezona je pokazala najveći uticaj na sadržaj GSH, fenola i YP kod kukuruza i soje, dok su sistem gajenja i đubrenje uticali na promene u sadržaju GSH i fenola. Sadržaj antioksidanata u zrnima sa većom masom je odgovarao povećanom nivou GSH kod kukurza, kao i povećanju nivoa GSH i fenola kod soje, dok su zrna manje mase imala već i sadržaj YP. Uopšteno, sadržaj antioksidanata je uglavnom bio povećan u zrnu kukuruza pri gajenju u naizmeničnim trakama, a u zrnu soje pri gajenju u naizmeničnim redovima. Bio-đubrivo je pokazalo najveći uticaj na povećanje sadržaja GSH u zrnu kukuruza i YP u zrnu soje, dok je organsko đubrivo ispoljilo uticaj na nakupljanje GSH i fenola u zrnu soje.

AB  - This study concerned the effect of different intercropping systems (alternating rows and alternating strips) of maize and soybean compared with single cropping, in combination with different fertilisers (biofertiliser, organic fertiliser, and urea) on the potential availability of magnesium (Mg), iron (Fe) and zinc (Zn) from grain, through their ratio with phytate (as inhibitor) and beta-carotene (as promoter). The higher grain yield and land equivalent ratio obtained under alternating rows + biofertiliser treatment demonstrated the improved ability of crops in close proximity for better utilisation of existing agro-ecological conditions. Alternating rows + organic fertiliser decreased the molar ratios phytate : beta-carotene, phytate : Fe, phytate : Mg and phytate : Zn, indicating increased availability of the mineral elements in both crops. However, alternating strips + organic fertiliser contributed mostly to an increase in beta-carotene, Mg, Fe and Zn concentrations in soybean. Increased grain yield of both crops was followed by decrease in beta-carotene and increase in phytate, particularly in maize. In soybean, beta-carotene could be considered as the main contributor to Fe availability. Accordingly, cropping in alternating rows or strips, combined with biofertilisers, could serve as fortification measures for improved nutritional quality of maize and soybean grain, without grain yield losses.

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.

AB  - The evaluation of pumpkin (Cucurbita maxima Duch.) and maize (Zea mays L.) intercropping productivity, under different farming systems: conventional farming vs. conservation farming was carried out on the chernozem type of soil at Zemun Polje, Serbia. Results obtained by the bivariate analysis of variance showed significant differences between different proportions of components in intercropped maize and pumpkins. Regarding the land equivalent ratio (LER), two rows of pumpkins and two rows of maize (proportion 2/3:1/3) were the optimum spatial arrangement in conventional farming system, while proportion 1/3:2/3 was optimal in conservation farming system. The yield of pumpkins proportionally increased with the increase of the plant population, although the intraspecies competition of pumpkins was very pronounced in intercropping with maize. The average fruit yield of pumpkins in the first year was lower in conservation farming practices in comparison with conventional farming practices. On the other hand, situation was complete opposite with pumpkin yield in second year of investigation, while significant decrease in maize yield was observed in the plots where conservation farming practices were applied. Growing pumpkins in mixture with maize probably costs a small farmer very little more effort, than the production of a sole stand of maize. At least where the productivity of mixture is dominated by one species, as with maize in maize-pumpkins intercropping, the competitive effect of the recessive species on the dominant is small.

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  - 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.

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.

Međutim, u 2005. godini, samo je prostorni raspored u trakama ispoljio efikasnost u pogledu sveže mase korova po jedinici površine.

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  - Korovi su oduvek bili ograničavajući faktor poljoprivredne proizvodnje, od samih njenih početaka pa do danas. Intenziviranjem gajenja pojedinih useva korovi su, zahvaljujući velikoj sposobnosti prilagođavanja, postali manje-više, otporni na uobičajene sisteme suzbijanja. Otpornost korova je dovela do povećane upotrebe herbicida, što je, takođe, povećalo ukupne troškove proizvodnje i rizik za životnu sredinu i zdravlje samih ljudi. Zbog toga je potrebno primeniti i druge, alternativne mere suzbijanja korova. Jedan od prirodnih načina rešavanja problema zakorovljenosti useva jesu mere kontrole korova, što se može postići posebnim sistemima zemljoradnje, u kojima združeni usevi zauzimaju važno mesto. Cilj ovog rada bio je da se utvrdi uticaj različitih hibrida kukuruza i prostornog rasporeda kukuruza i soje u združenom usevu na floristički sastav korovske sinuzije u prolećnom aspektu.

abstract = "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., Korovi su oduvek bili ograničavajući faktor poljoprivredne proizvodnje, od samih njenih početaka pa do danas. Intenziviranjem gajenja pojedinih useva korovi su, zahvaljujući velikoj sposobnosti prilagođavanja, postali manje-više, otporni na uobičajene sisteme suzbijanja. Otpornost korova je dovela do povećane upotrebe herbicida, što je, takođe, povećalo ukupne troškove proizvodnje i rizik za životnu sredinu i zdravlje samih ljudi. Zbog toga je potrebno primeniti i druge, alternativne mere suzbijanja korova. Jedan od prirodnih načina rešavanja problema zakorovljenosti useva jesu mere kontrole korova, što se može postići posebnim sistemima zemljoradnje, u kojima združeni usevi zauzimaju važno mesto. Cilj ovog rada bio je da se utvrdi uticaj različitih hibrida kukuruza i prostornog rasporeda kukuruza i soje u združenom usevu na floristički sastav korovske sinuzije u prolećnom aspektu. Ispitivanje je obavljeno na oglednom polju Instituta za kukuruz u Zemun Polju na černozemu u 2003. i 2004. godini. Ogled je izveden po sistemu aditivnog načina združivanja (additive intercropping system) u uslovima prirodnog vodnog režima.

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).

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  - 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.

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., 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.",
