Kholodchenko R. Performance naked oats depending on the growing technology in the Right-bank forest-steppe of Ukraine

The thesis is a theoretical substantiation and improvement of the optimal parameters of the formation of yield and grain quality of oat varieties in terms of Right-Bank Forest-Steppe of Ukraine. Established that the yield of naked oat varieties in the years close to the climatic norm reaches 3,6-4,0 t/ha, while the traditional hulled varieties to 5,27 t/ha. In unfavorable for the distribution of rainfall in 2011 it was at 2,8-3,9 t/ha in naked varieties and 3,7 t/ha in Parlamentskiy hulled varieties. The analysis and evaluation of the performance of oats depending on the studied factors (norms fertilizing, seeding rules, varieties) on the characteristics of growth, development and yield formation of oat plants. This economic and energy efficiency assessment of technologies growing studied varieties of oats. In particular, it was found that for grain yield of naked oat varieties Salomon and Skarb Ukraine adequate quality (class I) at 3,4-3,9 t/ha is the most cost-effective technology for the cultivation of cultivation, which involves seeding rate of 6 mn./ha and fertilization normally N90P60K90. The calculations it was found that traditional filmy variety of Parlamentskiy most cost-effectively grow without fertilizers at a rate of seed 6 mn./ha. Under these conditions, the yield was at 3,2 t/ha, net income amounted to 1147 UAH/ha.
