Optimization of the corn feeding by the use of mineral fertilizers and bacterial preparations in the conditions of ordinary black soil in Rostov region
In a three-year field experiment, the effect of fertilizers, bacterial preparations and their combinations on the productivity of crops of the average hybrid of corn in the ordinary black soil of the Rostov region was studied. The use of mineral fertilizers at a dose of N30P40 had a significant impact on productivity. The most effective races of strains of biological products providing high productivity of corn plants - Mizorin and 2P-7 were established. The optimal combination of mineral fertilizers and biological products was achieved on the variant using the preparation 2P-9, where the yield increased by 1.67 t/he, or 55.3% compared to the control variant.
