PRODUCTIVITY OF OILSEED FLAX DEPENDING ON THE TILLAGE SYSTEM

Abstract

The article presents the results of research on the influence of tillage system on biometric indicators
and productivity of oilseeds. The research presented in the scientific paper was carried out in the conditions
of Southern carbonate chernozems of perennial stationary fields of the A. I. Baraev research and production
center of grain farming.
In the course of the study, it was found that the development of ground organs at the stages of growth
and development of oilseeds and their productivity was positively influenced by the direct seeding and
minimum tillage system among various tillage technologies (traditional, direct seeding, minimum), in
particular, when the plant height in the zero and minimum processing system is 1.6-2.4 cm higher in grain
crop rotation and 0.7-1.7 cm higher in productive crop rotation, the number of seeds in boxes and boxes of
one plant was increased by 6.7-7.3 and 59.9-62.3 pieces in grain crop rotation, respectively, and by 3.6-9.2
and 67.7-89.6 pieces in productive crop rotation. It was found that the total weight of seeds on 20 plants is
8.3-9.3 g in grain crop rotation, 7.6-12.3 g in productive crop rotation.
Minimum tillage and direct seeding of the soil in the grain crop rotation variant with an average yield of
three years gave a yield of 2.0-3.7 c/ha, respectively, compared to traditional tillage, and 1.9-3.3 c/ha more in
the productive crop rotation variant.
