Abstract
Under conditions of the Central Nonblack Earth Region on sod-podzolic soil, the reaction of oat varieties Yakov, Bulanyi, Zalp, Ulov, Golozernyi (line 61h) to fertilizers and crop protection agents was investigated. Among the tested varieties, Yakov variety with a yield up to 10 t/ha at high-intensive technology was allocated. Zalp and Bulanyi varieties also exceeded by productivity the standard variety (Ulov) by 0.3–0.9 t/ha. Increases of the yield depending on seeding rate changed from 12 to 64%, and the grain protein content changed from 9.8 to 17.8%. The grain protein content was the highest in the Golozernyi variety. The treatment of crops with herbicides reduced contamination by 65–95%, and application of crop protection agents promoted preservation of the yield and improved grain quality.
