Over the years of research, rapeseed sown by the second crop at zero and minimum plowing
process allowed us to obtain a mathematically provable increase in comparison with the control and
amounted to 3.1 and 3.3c/ha, respectively (Table 4), with the control variant's yield of 14.0 c / ha, in
weather and climatic conditions, option 5 "legume culture" reduced the yield by 2.4 c/ha compared to
the control, which is due to the low content of productive moisture before sowing rapeseed compared
to other predecessors, due to the low content of autumn-winter moisture charging 2015-2016 (table 4).
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.
