Conclusion. Based on the research conducted in 2015-2017, aimed at developing technological methods that ensure a high sustainable yield of spring wheat and rapeseed, the following conclusions are drawn: It is established that over the years of research, the effect and aftereffect of various methods of preparing precursors on the accumulation and preservation of productive moisture reserves before sowing spring rapeseed was 88.5-82.3 mm. Nitrate nitrogen content before sowing for rapeseed in the pure steam variants, the content of nitrate nitrogen is higher than in other variants and amounted to 19.1 mg per 1000 g of soil; zero and minimum plowing process -17.2; 17.4 mg. per 1000 g of soil, in the occupied steam and legume culture variants- 11.8; 13.0 mg per 1000 гg of soil the soil. Over the years of research, various methods of preparing precursors have had an effect and aftereffect on the yield of spring rapeseed. Over the years of research, rapeseed sown by the second crop in zero and minimum plowing process allowed us to obtain a mathematically provable increase in comparison with the control and amounted to 3.1 and 3.3 c/ha, respectively, with a yield of 14.0 c/ha from the control variant. жүктеу/скачать 7.12 Mb.
