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.

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.
