Efficiency evaluation of oil flax cultivation under different methods of herbicide application

Abstract

The article presents long-term research (2018-2020) on the effect of herbicide tank mixtures Herbitox, SC (1.0 l/ha) and Miura, EC (1.2 l/ha); Cleo, WDG (0.12 kg/ha) and Miura, EC (1.2 l/ha), as well as of the separate application of these preparations on the productivity of oil flax (variety FLIZ of the breeding of V.S. Pustovoit All-Russian Research Institute of Oil Crops) in the zone of unstable moistening on leached chernozem of the Western Ciscaucasia. We established that on average for three years, in case of treatment of oil flax with a tank mixture of herbicides Herbitox, SC (1.0 l/ha) and Miura, EC (1.2 l/ha); Cleo, WDG (0.12 kg/ha) and Miura, EC (1.2 l/ha), we got higher yields compared to their separate application – 1.39 and 1.37 t/ha, respectively, oil yield – 0.55 t/ha; there was high net income of 21629 and 21004 rub/ha with a profitability of 80 and 78 %, respectively.
