Assessment of some agricultural techniques for increase of grain yield and quality of cereal crops in Amur river region
The article presents the results of research on influence of sowing dates, fertiliser doses and enzyme-mycotic depletion of seeds (EMDS) on the formation of quality indices of cereal crop grain. It has been established that under Amur river region conditions the best time for spring wheat and oat sowing is the one when the sum of positive air temperatures is 50...100°C, and for barley - 50°C. Delay sowing reduces yield and seed quality. Additional nitrogen fertilizing in doses of 10...30 kg/ha in tillering phase, against the recommended dose of basic fertilizer (N<sub>30</sub>P<sub>60</sub>K<sub>30</sub>), increases wheat grain yield, but decrease sowing qualities of seeds.
