OPTIMIZATION OF SOWING AND HARVESTING OF OAT

Abstract

The paper presents the results of the studies on possible oat yield losses due to the violation of sowing and harvesting time. It’s established that with late sowing (10 and 20 days after the optimal period) and harvesting in time the yield is reduced by 16.5 dt/ha (24.2%) and 32.9 dt/ha (48.2 %) respectively. Oat harvesting within 5 days after grain ripeness doesn’t result in significant yield losses. With sowing this crop during the optimal period and late harvesting (10 and 20 days late) the losses amount to 3.9-5.8 dt/ha (5.7-9.3 %) and 11.5-13.8 dt/ha (16.8-22.3%) respectively. Violation of organizational and technological norms of oat sowing and harvesting reduce the grain yield by 3.9-42.7 dt/ha (5.7-62.5%).
