EFFICIENCY OF THE USE OF OATS STRA W AND NITROGEN FERTILIZERS IN THE PROCESS OF WINTER WHEAT CULTIVATION
The paper states the results of the research on the economic efficiency of oats straw use and increasing doses of nitrogen fertilizers in the process of winter wheat cultivation. It’s established that on average for two years the reduction of winter wheat yield under the influence of oats straw is registered only on a nitrogen free background. With the application of increasing doses of nitrogen the straw of a preceding crop increases the yield by 0.6-l,0 %. The highest net profit of winter wheat cultivation is made with the use of oats straw for fertilizers and application of nitrogen in a dose of N70+70+20.
