Productivity and quality of grains of oat varieties bred by Nemchinovka Moscow Scientific research Institute of Agriculture at different technologies of cultivation

Resumo

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.
