PRODUCTIVITY OF GRAIN FALLOW ROTATION WITH SEEDED FALLOW AND PRIMARY TILLAGE
The article presents the results of studies on the productivity of grain-fallow crop rotation with seeded fallow in the cultivation
of crops for primary tillage. The comparison of the productivity of crops by deep and shallow treatments of the soil is
carried out. Crop rotation of the highest productivity – 3.45 m tons of fodder units/ha – was obtained by differentiated processing
of soil, which is higher than the control (moldboard treatment) by 0.24 tons of fodder units/ha and higher than the above
subsurface treatment by 0.29 tons of fodder units/ha. The research results confirm the effectiveness of deep treatments and that
the decrease in the depth of processing leads to a decrease in productivity. So, reducing the depth of processing led to lower
productivity of 0.39 tons of fodder units/ha for moldboard treatment, 0.4 tons of fodder units/ha for moldboard and 0.47 tons of
fodder units/ha for the differentiated treatment. Distance from spring wheat seeded fallow (pea and barley) have led to lessened
productivity, i. e. the productivity of the second spring wheat from the first wheat. Namely, the second productivity of spring
wheat is less than the first wheat 0.19–0.23 tons of fodder units/ha versions of deep processing, 0.14–0.18 tons of fodder units/
ha shallow treatment, 0.14 and 0.19 tons of fodder units/ha at the zero treatments.
