Abstract (English):
Materials of research on the effectiveness of application of complex microfertilizers on different backgrounds of mineral nutrition in the cultivation of hybrid Aris in the zone of unstable moisture in the Central Caucasus for 2021 - 2023 are presented. During the experiment, the maximum yield of sunflower oilseeds (3.57 t/ha) was achieved when applying the calculated dose of mineral fertilizers on the planned yield of sunflower 3.5 t/ha (N90P80K62), which significantly exceeded the indicators of the control variant, as well as the recommended (N60P70K40) and calculated doses of mineral fertilizers by 1.54 t/ha (N74P64K48), 0.91 and 0.47 t/ha, respectively. The use of microfertilizers in the experiment increased the yield level of the crop depending on the background of mineral nutrition by: 0.26 - 0.37 t/ha (on control), 0.48 - 0.61 t/ha (on recommended - N60P70K40), 0.40 - 0.59 t/ha (on calculated for 2.5 t/ha - N74P64K48), 0.23 - 0.44 t/ha (on calculated for 3.5 t/ha - N90P80K62). The highest indicator of oil content on all studied backgrounds of microfertilizers, recorded on the background of the recommended dose of mineral fertilizers N60P70K40.
