The main goal of our investigation was to determine the influence of different mineral fertilizer rates on the formation of corn hybrids productivity and their dependence on hydrothermal conditions. Medium-early hybrid SY Fenomen (FAO 220) and medium-ripe SY Torino (FAO 310) were selected and analysed for research. The corn fertilization system consists of three methods:Main, row and top dressing. Under conditions of optimal fertilization inthe growing season corn can provide high yields on almost all soils.almost all soils. Scientists distinguish two important stages of plant developmentcorn, the so-called critical phases, regarding the provision of their macro- andmicroelements, these are the phases of 3-5 and 7-8 leaves. From the provision of elementsnutrition, especially pay attention to the presence of phosphorus, depends onthe formed number of cobs on the plant and grains on them. Corn reacts strongly to nitrogen fertilization. To ensurehigh efficiency of its application and optimization of the dose, in addition to samplingsamples and expected yields, it is necessary to determine the amount of nitrogen contained in the soil.Contained in the soil. The amount of soil nitrogen can be very different andrange from 20-100 kg N depending on the predecessor and itsnutrition, soil class and agricultural practices used. Nitrogen is the most important of all nutrients that affect the level ofcorn yield. Corn consumes nitrogen up to the phase of 8 leaves, until thismoment only 2-3% of nitrogen is absorbed, from the phase of 8 leaves to the phase of dryingflower columns (hair) on the cobs - 85% of the total amount of nitrogen.The rest of the nitrogen corn continues to consume almost until the beginning of cobs. The influence of mineral fertilizers on the formation of individual productivity and the use of mineral fertilizers at a dose of N128P128K128 + N70 provided the highest height of maize plants 212.6 cm for SY Fenomen and 227.4 cm for SY Torino. The height of cob attachment under these conditions was 82.7-88.4 cm. Additional use of 70 kg of nitrogen on the background of N128P128K128 allowed to form the highest biometric values of the cob. Thus, in the hybrid SY Fenomen the length was 24.4 cm and the diameter was 5.1 cm, while in the SY Torino hybrid it was 25.6 and 5.3 cm, respectively. The use of a complete fertilizer system (N128P128K128 + N70) in the cultivation of corn hybrids has increased grain yield from cobs to 82.8-83.6% against 79.5-80.8% in control, and accordingly the weight of 1000 seeds up to 336-345 g against 318-329. The use of mineral fertilizers had a positive effect on the formation of grain productivity indicators of corn hybrids. And the more nitrogen fertilizers were applied, the higher was the yield. Compared to the variant without fertilizer, the yield of corn hybrids increased by 83-90% and amounted to 12.18-12.88 t ha-1.
