AB  - Crop density is a means that controls grain yield establishment. This study was focused on evaluating the effect of four crop densities (CD1—50,125 plants ha−1, CD2—59,523 plants ha−1, CD3—69,686 plants ha−1, and CD4—79,365 plants ha−1) on yield components, grain yield, sustainable yield index (SYI), and rain use efficiency (RUE) of the maize hybrids ZP 500, NS 5010, and AS 534 during 2016–2018. In 2017, due to unfavorable meteorological conditions, ear length, number of grains per ear, grain weight per ear, 1000-grain weight, grain yield, SYI, and RUE were low compared to 2016 and 2018. The hybrid NS 5010 had the lowest ear length, number of grains per ear, grain weight per ear, 1000-grain weight, grain yield, and SYI. Increasing crop density significantly decreased yield components and increased grain yield, SYI, and RUE. The lowest ear length was recorded in treatments CD3 and CD4, the lowest number of grains per ear, grain weight per ear, and 1000-grain weight in treatment CD4. However, the highest grain yield, SYI, and RUE were recorded in the CD4 treatment because the number of plants per unit area is an essential determinant of the final grain yield.

AB  - Cover crops play an important role in low-input cropping systems, increasing the
use of agro-ecosystem services. Due to the lack of information about the impact
of cover crops and bio-fertilizers on popcorn maize (Zea mays everta Sturt.)
growth and yield quality, especially the popping volume and nutritive quality,
such as concentrations of protein and mineral elements, this research aimed to
provide essential information. The interrelation between popcorn maize
productivity and quality with important groups of soil microorganisms presents
additional novelty. The results demonstrated that field pea is a beneficial cover
crop, especially when combined with a bio-fertilizer, supporting the
accumulation of maize biomass, chlorophyll, yield potential, and the
concentrations of protein, Ca, Mg, Fe, and Zn. In addition, field pea residues
promoted N-fixing bacteria, and the number of total microorganisms, especially
actinomycetes and decomposing bacteria, which could promote nutrient uptake
and grain quality. Residues of cover crop mixtures, common vetch + winter oats
and field pea + winter oats, promoted the total number of microorganisms in the
soil, and up to the end of vegetation, a greater number of decomposition and
ammonification microorganisms were found, especially when the bio-fertilizer
was applied, which consequently could support greater maize biomass. Popping
volume, as a main trait of popcorn maize, had the highest value in the common
vetch + winter oats variant, supporting again the statement that quality traits
could be enhanced in sustainable production. Unlike living cover crops, mulch
mainly affected soil microbial communities and promoted the development of
actinomycetes and cellulolytic microorganisms during the growing season. The
results of this research could contribute to the development of sustainable
popcorn maize production for improved grain quality. They could also serve as
a basis for isolating beneficial soil microorganisms to develop new bio-fertilizers
that could improve maize production in synergy with cover crops

AB  - The experiment with low-input technology of soybean was conducted at the research and
study field "Radmilovac", Faculty of Agriculture Belgrade in 2022 on the luvic chernozem
soil type, in completely randomized blocks. Cropping system included tillage with a disc
harrow at 20-25 cm with the complete previous crop residues incorporation and the presowing tillage with a harrow. The basic fertilization was conducted in autumn with 300 kg ha1 NPK (15:15:15). For top dressing in spring, the following microbiological fertilizers were
applied: biofertilizer ("Slavol", manufacturer "Agrounik" Serbia) with 5.0 l ha-1
in two
treatments and Eko lame 10 l ha-1
in three treatments. The top dressing in the control variant
was done with nitrogen fertilizer AN at the rate of 40 kg ha-1 N. The soybean (NS Maximus)
cultivars were used. The crop was grown in a six-crop rotation (winter wheat-maize-spring
barley+red clover-red clover-soybean-sunflower). Statistical analysis confirmed that top
dressing had a greater effect on weediness of soybean. The weed community in investigated
crops consisted of 11 weed species, with dominating: Solanum nigrum L., Polygonum
aviculare L. and Avena fatua L., (annual species) and Convolvulus arvensis L. and Sorghum
halepense (L.) Pers. (perennial species). The obtained results show that the highest number of
weeds, weeds per species, fresh and air-dry biomass were recorded in the control treatment.
The statistically lowest values for the number of weed plants per species were recorded in the
treatment with Eko lame, but for fresh biomass in the treatment with Slavol. The differences
in weediness in the variants with microbiological fertilizers were not statistically significant,
while there were statistically very significant differences compared to the control. Application
of microbiological fertilizers affected the initial faster growth of soybean plants and increased
competitiveness against weeds.

AB  - Maize silage is source of palatable and high-energy forage for ruminants. Therefore, production of high quality forage maize represents an essential strategy for stable production of milk and meat on livestock farms. This study examined the effect of harvest date (early dent, at half milk line, at three quarters milk line and black layer) on the quantitative and qualitative parameters of whole maize plant under contrasting climatic conditions in the Srem - Serbia. A 2 × 4 factorial (two years and the four cutting times) randomized blocks design was used, with three replications. The plant height, stem diameter, number of leaves per plant, forage yield, dry matter yield and dry matter content were higher in 2014 probably due to favorable weather conditions. With the delay of the harvest the forage yield, crude protein content, acid detergent fiber (ADF) and neutral detergent fiber (NDF) decreased, and dry matter yield, dry matter content and ear percentage increased. Sufficiently high dry matter content and ear percentage were achieved at the third harvest. However, the delay of harvested time reduces the quality parameters of the biomass, but this loss in the entire plant is moderated by grain filling.

AB  - The successful production of soybeans is largely dependent on the sowing time, because
every sowing outside the optimal time contributes significantly to yield losses. This field study
aimed to evaluate the effects of sowing time (optimal—April 5; late—April 27) on the quantitative
and quality traits of three soybean genotypes (Galina—0 maturity group; Sava—I maturity group;
and Rubin—II maturity group) under dryland conditions in Vojvodina Province (Serbia) during
2017 and 2018. The genotype Sava had higher yield in climatic-unfavorable 2017, while Rubin had a
higher yield in climatic-favorable 2018. The yields significantly decreased when the soybeans were
sown in late April due to reductions in the number of pods per plant, seed weight per plant, and
1000-seed weight. The reduction in yield components was likely due to the accelerated senescence of
plants and the negative effect of high temperature and low precipitation during the seed filling stage.
Accordingly, the various sowing times and properly chosen genotypes provide a better utilization of
soil and water resources. A proper genotype selection and sowing time can contribute to a high yield.
At the same time, the protein and oil contents can be altered by the sowing time, especially under
water stress during the reproductive stage.

AB  - Field experiment was conducted to examine the impacts of two sowing dates (8 April - first date of sowing and
21 April - second date of sowing) and four nitrogen rates (0, 60, 120 and 180 kg ha-1) on the productivity of maize hybrid ‘ZP 434’ in the Pannonian region of Serbia during 2016 and 2017 seasons. The dry period during late
vegetative development and grain filling stage in 2017 decreased ear traits, grain yield, starch and oil contents,
nitrogen agronomic (NAE) and nitrogen use efficiency (NUE). The highest number of grains per ear, starch and oil
contents, starch and oil yields and lower rainfall use efficiency (RUE) and protein content were obtained from the
early sowing date. The ear traits, grain yield, RUE, protein content, oil content and yield of starch, protein and oil
significantly increased while NAE, NUE and starch content significantly decreased with increasing nitrogen rate.
The results indicated a significant inverse correlation between starch and protein contents, which prevents the
improvement of these two parameters simultaneously. Thus, timely sowing and nitrogen input should be used as
long term management strategies for increasing maize yield and grain quality.

nitrogen agronomic (NAE) and nitrogen use efficiency (NUE). The highest number of grains per ear, starch and oil
contents, starch and oil yields and lower rainfall use efficiency (RUE) and protein content were obtained from the
early sowing date. The ear traits, grain yield, RUE, protein content, oil content and yield of starch, protein and oil
significantly increased while NAE, NUE and starch content significantly decreased with increasing nitrogen rate.
The results indicated a significant inverse correlation between starch and protein contents, which prevents the
improvement of these two parameters simultaneously. Thus, timely sowing and nitrogen input should be used as
long term management strategies for increasing maize yield and grain quality.",

AB  - The main nitrogen (N) sources in soybean production originate from soil fixing bacteria
Bradyrhizobium spp. and from mineralization of soil organic N. These sources of N are often not
su cient to cover the N needs of the soybean. The present two-year field study aimed to evaluate the e ects of soybean genotypes (Valjevka and Galina) and rates of starter fertilizer N (0, 30, 60, and 90 kg ha�����1) on quantitative and qualitative parameters and on rain use e ciency (RUE) under contrasting weather conditions in the Pannonian region of Serbia. A field study conducted during two di erent growing seasons: first year with unfavorable weather conditions and second year with favorable weather conditions. As expected, the quantitative parameters, oil content, and RUE were higher in the year with favorable growing season, the second one. According to measured parameters, the genotype Valjevka performed higher yield potential as compared to the genotype Galina. The highest values of quantitative parameters and RUE were recorded at 60 kg N ha�����1, protein content at 90 kg N ha�����1 and oil content 0 kg N ha�����1 (control). This study suggests that proper genotype selection and application of 60 kg N ha�����1 as a starter dose with rhizobial inoculation could contribute to the high yield, while protein could be altered by N amount, independently on genotype.
