EFFECT OF PROTECTANT OF SOWING SEED TREATMENT ON SEED QUALITY AND YIELD OF SOFT WINTER WHEAT GRAIN

Abstract

According to scientific research, it was found that the use of pre-treatment of wheat seeds of soft winter by bacterial substances polimiksobakteryn (150 ml/t) and diazofit (150 ml/t) and joint processing of growth regulators pennant (120 ml / t) and agate – 25K (60 g/t), against fertilizing N₂₅P₂₅K₂₅, N₅₀P₅₀K₅₀, N₇₅P₇₅K₇₅ provides higher vigor, laboratory and field germination. According to scientific studies it was found that the use of presowing seed by treatment growth regulators Vympel (120 ml/t) and Аgate-25K (60 g/t) by fertilizing N₇₅P₇₅K₇₅ vigor seeds 2.7%, 1.7% seed germination, survival soft winter wheat plants increased by 10.2%; by bacterial drugs: polimiksobakteryn (150 ml/t) –9.4%, diazofit (150 ml/t)  by 9.3% , that exceeds control.
