Plant protection of a new variety of spring weat Marsianka

Abstract

The results of the study of the effect of seed dressers and herbicides on the yield and economic efficiency of the new variety of spring wheat Marsianka are presented. The experimentation, observations and registrations were carried out according to generally accepted methods. In the tillering phase of wheat, the incidence of root rot was 22% lower in crops with dressed seed. In the experiment a higher retention of yield from the disease 77.5% and an increase of 0.38 t/ha were obtained in the variant with the preparation Maxim Plus, VSK with the rate of 1.5 l/t. Using the preparations Maxim Plus, VSK and Vial TrasT, VSK (0.4 l/t), grain unit increased to 799 g/l, vitreousness - to 65.4%, 1000 seed weight - to 38.6 g, protein content - to 16.2%, gluten content in grain - to 36.0%. Vial TrasT, VSK provided better economic performance: net income increased by 23.3%, the cost per tonne of grain decreased by 9.1% and profitability increased by 20.2%. Crop treatment in tillering phase with a tank mixture of herbicides Lastik TOP, MKE (dose 0.4 l/ ha) and Magnum, VDG (0.008 kg/ha) resulted in the highest yield in the experiment 3.63 t/ha with improved quality of grain (natural weight 798 g/l, vitreousness 67.9%, grain protein content 17.3%). The herbicide Lancelot 450, VDG and the tank mixture Puma Super 100, KE + Pruner Turbo, MD ensured a weight of 38.1 g and a gluten content of 34.7%. Crops treated with the herbicide Lancelot 450, VDG, the tank mixtures Lastik TOP, ME + Magnum, VDG and Balerina, SE + Mortira, VDG provided the highest net income of 15,200-15,300 p/ha. A maximum profitability of 116.9% and a minimum cost of 3,688.66 p/t were obtained from the use of Greneri, VDG.
