Урожайность овса яков в зависимости от предпосевной обработки семян и норм высева

Abstract

The effect of pre-sowing treatment and standards of their seeding rates on the productivity of oats of Yakov breed was established on the basis of results of two years of research on the sod-medium medium-loamy soils of the Middle Urals. The efficacy of pre-sowing seeds treatment with drugs Lamador, Planriz, Vial TrasT, ZhUSS was proved by increasing the productivity to 0.14-0.30 tons per hectare. The optimal seeding rate for oats of Yakov breed is 5 million pieces of seeds per hectare in the Middle Urals. We revealed the direct close correlation of Yakov oats productivity with inflorescence productivity (r = 0.84), with the weight of 1000 grains (r = 0.82), with plant height (r = 0.81) and with the kind of grain (r = 0.80).
