Plant growth regulators and fertilizers in cultivation technology of peas

Abstract

Studies showed that an increase in doses of mineral fertilizers for peas up to N₄₀P₄₀K₄₀ and further up to N₆₀P₆₀K₆₀ and, in general, an increase in fertilization level of crop rotation link to N₂₄₀P₂₁₀K₂₁₀ and further up to N₃₉₀P₃₀₀K₃₀₀ provide a significant improvement of conditions for plant soil nutrition, which have a direct impact on the additional formation of vegetative and generative organs of pea. The mineral fertilizer N₄₀P₄₀K₄₀ provides the biggest increase in the pea grain yield, if the level of fertilization of the crop rotation link is N₂₄₀P₂₁₀K₂₁₀. The most effective agroproducts included in the cultivation technology of peas are considered to be Gumi-20 M rich and Aquadon-micro. The combination of the studied factors was achieved with N₄₀P₄₀K₄₀ and N₆₀P₆₀K₆₀ with Gumi-20 M rich and Aquadon-micro. On average, the pea yield in these variants in three years was from 3.21 to 3.36 t/ha.
