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.


Keywords:

productivity, crop rotation, tillage, full fallow, annual grasses, spring wheat.
