SPECIAL ASPECTS OF SOWING TERMS AND NITROGEN NUTRITION IN THE CULTIVATION OF NAKED OAT UNDER BELARUS CONDITIONS

Abstract

The results of the researches on the optimization of sowing terms and application of nitrogen fertilizers in the cultivation of naked oat var. Korolyok on sod-podzolic sandy loam soil in the Central zone of Belarus are shown. It was discovered that in order to obtain the highest yield, naked oat should be sown in 7 days after the onset of physical ripeness of soil and nitrogen should be applied in a dose of N90 before presowing cultivation or in parts N60+30. In that case, the naked oat plants formed grains with the weight of 1000 grains of 26.4-27.2 g and high-grained panicle (57.7-58.4 seeds) which provided the grain yield of 47.7-50.9 dt/ha.
