AB  - This research aimed to determine the effects of different cover crops and application of bio-fertilizer on dynamic of nitrogen in the soil and sweet maize yield. Also, we evaluated the effect of fall-winter species (common vetch, field pea, winter oats, fodder kale) and a mixture of vetch and field pea with oats used as cover crops, as such as dead organic mulch and traditional variant, without coverage on biomass, chlorophyll and protein content in leaves and grain of main crop. Biomass production and N uptake by cover crops ranged from 4.25 to 90.20 kg ha(-1) and from 0.34 to 133.80 kg ha(-1) N, respectively, depending on cover crop type. At harvest soil nitrate content in treatments with cover crops was 50-90% lower than in the control, reducing spring N leaching risk. Residual mineral N significantly increased with application of microbiological fertilizer. The chlorophyll content of the main crop was significantly lower in treatments without cover crops. Consequently, sweet maize yield was the highest in fodder kale and field pea (7263.83 and 7177.27 kg ha(-1)) treatments, but the smallest in winter oat and common vetch (6802.47 and 6184.14 kg ha(-1)). In terms of all investigated traits, particularly grain yield, cover crops and microbiological fertilizer expressed more efficiency in the dry year. It could be concluded that N content should be controlled effectively by sowing main crops after planting of cover crops in biological farming systems in a semiarid region.

AB  - Dominance of grass weeds in maize crop occurs due to a lack of selective herbicides for their control. With sulphonylurea herbicides this problem became under control, but a problem with selectivity was developed, particularly in maize seed crop. The effect of sulphonylureas and foliar fertiliser on maize lines was evaluated by visual estimation, grain yield, as well as the alterations in the content of antioxidants: free thiolic groups, phenolics and soluble proteins in the leaves. The proteins content did not vary significantly under the influence of herbicides, compared to the control, opposite to free thiolic groups and phenolics. The differences in the content of phenolics and thiolic groups in the treatments with herbicides plus foliar fertiliser indicated that herbicide stress was more rapidly overcome. Most of the genotypes expressed significant increase of grain yield in the treatments with foliar fertiliser, compared to control and analogous treatments with herbicides.

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  - Weeds are among main limiting factors in sweet maize production. Commercially grown sweet corn hybrids (Zea mays saccharata Sturt.) vary widely in competitive ability against weeds which interference differentially affects yield and ear traits important to processing and fresh markets. A total of 28 sweet corn hybrids of different FAO maturity groups have been developed at the Maize Research Institute, Zemun Polje, and released by the the Commission for the Variety Releasing. In order to obtain high yields of good quality the scientists have been searching for the most appropriate growing practices. Therefore the objective of the present study was to determine the effect of four plant densities (40 000, 50 000, 60 000, and 70 000 plants/ha) on the level of weed infestation, yield and shelling percentage of four sweet maize hybrids (ZP 424su, ZP 462su, ZP 504su, and ZP 521su) in 2008 and 2009. Total fresh weight and the total number of weeds decreased with increasing sowing density, which was more prominent in 2008. Results of the analysis of variance showed that investigated factors, year, sowing density and hybrid had significant influence on fresh ear yield and shelling percentage. Sowing density affected fresh ear yield in the way that the denser sowing was, the higher yield was. Hybrids ZP 424su and ZP 462su gave higher fresh ear yields than other two. However, hybrids with less fresh ear yield (ZP 504su and ZP 521su) gave better shelling percentage. These results suggest that ZP 424su and ZP 462su can be preferable for fresh consumption and ZP 504su and ZP 521su for processing.

AB  - The level of weed infestation directly affects the intensity of competitive relationship between sunflower crops and weeds. The greatest damage is caused by annual, broad-leaf and invasive weeds, such as Ambrosia artemisiifolia L., Xanthium strumarium L. and Datura stramonium L. Suppression of these weeds is difficult because of deficiency of adequate herbicides and because in years with dry springs, such as in 2009, the use of herbicides gives no results. This two-year study dealt with the observed effects of pre-emergence flurochloridone + s-metolachlor herbicides on the distribution of weeds in different stages of sunflower development. Weed infestation was estimated over the sunflower developmental stages, i.e., in the periods when weeds were removed and when the total fresh and dry biomass of the weed species was determined. Simultaneously, in order to monitor the effects of weeds in dependence on herbicides application and the duration of competition, the sunflower plant height was measured. At the end of the life cycle, the yield and the oil content of the sunflower seeds were established. The total fresh weed biomass changed in dependence on the sunflower developmental stages and was always lower on the herbicide-treated area. This affected the sunflower plant height, yield and the oil content, which were higher, on the average, in the variants with herbicide applications (70.4 cm, 2959.7 kg ha-1 and 42.0%) than in the variants without herbicides application (57.4 cm, 2711.1 kg ha-1 and 40.1%). Weed suppression in the sunflower crop has to be done with adequate herbicides and in due time in order to suppress a significant reduction in morphological and yield parameters.

AB  - The influence of the growing population density of jimsonweed on maize productivity was studied in the experimental field of the Maize Research Institute, Zemun Polje on the chernozem type of soil in 2000 and 2002. The additive experiment was applied as a broadly used design for crop-weed interactions studies. The infestation was artificially created and the density of weed ranged from 0, 1, 3, 6 and 10 plant m(-1) in rows and between maize rows. The increase of the growing population density of jimsonweed decreased significantly plant height, dry biomass per plant and grain yield of maize. The weed density had a more significantly affect on the plant height and dry biomass per plant of maize than plant arrangement of weeds. The highest decrease of maize productivity was in variant jimsonweed in rows with 10 plant m-1. Yield was significantly affected by the weed position in both seasons and the decrease was more significant in variants with weed in rows of maize. The greatest observed yield loss (74%) was obtained in the variant of 10 plants m-1 of weed in row of maize in 2002. Average values of yield losses in all variants (11-57%) were over than 5%, which is considered the a weed threshold for maize. A lower yield loss than the weed threshold was recorded on two variants with jimsonweed between rows (6 and 1 plant m-1) in hot and dry 2000.

AB  - An (Randomized Complete Block) experiment with a maize and soybean intercropping system was set up at the experimental school of the Faculty of Agriculture-Radmilovac, Belgrade, Serbia and Montenegro. The experiment were carried out during 2002 and 2003 on the eutric cambisol soil type. Two spatial planting arrangements were applied: strip intercropping and alternate rows. Intercropping was done according to the method of replacement series and the main goal of this approach is to exchange the particular number of plants of one species with another. This examination included four experimental hybrids of maize from various FAO groups of maturity (400, 500, 600 and 700) and a soybean cultivar, ZPS-015 (maturity group O). The aim of this paper was to determine the optimal plant arrangement pattern of maize and soybean toward getting the maximum aboveground biomass with the best quality of silage. Likewise it is important to examine the advantage of late maturity maize hybrids (FAO 600 and 700) compared with medium early maturity hybrids (FAO 400 and 500). Weather had a large influence on biomass productivity. The increase of intercrop productivity in 2002 (when rainfall was adequate) was from 25-38% (strips) and 27-43% (alternate rows), while in 2003 (when rainfall was inadequate in parts of the growing season) this increase was a little bit lower: 8-18% (strips) and 13-40% (alternate rows). Intercrop variants with medium late hybrids of maize (FAO 600 and 700) gave significantly higher yield of above ground biomass in 2002. In second year of the examination 2003, the advantage was on the side of intercrop with hybrids of shorter vegetation period (FAO 400 and 500) because of drought. The greatest yield appeared in 2002 in variants of alternate rows intercrop with hybrids FAO 400 and FAO 700.

AB  - In this paper, are presented the results of physical and chemical investigations of differently treated samples of oak acorn. The aim of this investigation is to estimate the influence of thermal treatment on physical and nutritive characteristics of investigated samples. Oak acorn, Quercus robur, (belonging to Fagaceae family) was investigated in native and thermally treated forms. By subsequent extraction of dry toasted oak acorn (Quercus semen tostum) the aqueous extract was obtained which is then dried in a spout-fluid bed. The content of total polyphenols, then polyphenols unadsorbed on hide powder and tannins was determined by spectrophotometric methods with phosphor-wolfram acid according to Ph. Yug. V. Galic acid was determined by HPLC. The total antioxidant activity (TAA) of the aqueous extract compared to the control samples of pigs fat and synthetic antioxidant butylated hydroxyanisole BHA was estimated by Schall-Oven test at 60 +/- 1 degrees C in dark, and oxidative changes were determined by measuring the Peroxide value (PV). For determination of macro- and microelements the method of AAS was used. By detecting the changes of PV it is established that aqueous extract was influencing the stability of pigs fat, that is, showing the antioxidant activity. The activity was increasing with increasing concentration in tested samples. The obtained results regarding the total polyphenols content, the content of galic acid, nitrogen compounds, macro and microelements show that acorn, after treatment, was retaining and in some cases improving its functional properties.
