ECONOMIC EFFICIENCY OF MEADOW CLOVER CULTIVATION IN RELATION TO SOWING RATES, NITROGEN FERTILIZRES DOSES AND HARVEST TIME OF A COVER CROP
The article states the results of the research on identifying the most optimal sowing dates, doses of nitrogen fertilizers application to a cover crop, sowing rates of clover and barley. It’s established that with cultivating clover for green mass the highest net income (2280.1-2263.4 ru-ble/ha) and level of profitability (130.9-123.8%) is provided when it is sown without a cover crop in April at a rate of 4 and 6 mln ps/ha. When seeding clover with a cover crop the highest net income (2162.7-2262.7 ruble/ha) and profitability (102.5%) is provided with clover sowing rate of 4 and 6 mln ps/h and barley harvest at the stage of milk-wax ripeness at a sowing rate of 4 and 6 mln ps/ha against the background of N<sub>60</sub> application.
