Efficiency of complex application of fertilizers and plant protection means in cultivating of corn

Abstract

The maximum yield of corn grain was obtained in the complex application of mineral fertilizers in a dose of N₁₂₀P₁₂₀K₁₂₀ against the background of the aftereffect under manure and plant protection products and amounted to 8.42 t / ha. Applied means of plant protection increased the yield by an average of 12.5-41.0%. The greatest payback of 1 kg of NPK yield increment was noted in the variant with application of mineral fertilizers in a dose of N₆₀P₆₀K₆₀ and was 14.4-22.1 kg. Thus, the integrated application of chemicalization means contributes to the maximum realization of the productivity potential of maize for grain and the return on investment. The methods of basic tillage did not have a significant effect on the yield of corn.
