Influence of macro-, micro-fertilizers and growth regulator on yield, yield structure and grain quality of spring wheat

Abstract

The development and introduction into production of new forms of complex fertilizers containing nutrients in a balanced amount (macro- and microelements) makes it possible to optimize plant nutrition and at the same time reduce the cost of their use. This article presents the results of research on the use of new forms of macro-, microfertilizers and growth regulators of domestic and foreign production on linear growth, crop structure and grain quality of spring wheat on soddy-podzolic light loamy soil.
The maximum height of plants (111,0 and 111,9 cm), the largest number of productive stems (563 and 583 pcs/m²), the mass of 1000 grains (39,8 and 39,9 g), the maximum yield (69,7 and 70,3 c/ha) of spring wheat grains were noted in the variants of MicrotimCopper L and Nutrivant Plus against the background of N_60+30+30 P₇₀K₁₂₀.
The highest content of crude protein in spring wheat grain was noted in the variant with the use of N₆₀P₆₀K₉₀, N₆₀₊₃₀P₆₀K₉₀ – 13,3–13,6 %. Vitreousness ranged from 69,7 to 80,8 % and did not increase significantly according to the variants. The maximum gluten content was noted in the variants with the use of MicroStim-Copper L and Nutrivant Plus against the background of N_60+30+30 P₇₀K₁₂₀ – 33,2 and 34,4 %.
