IN THE UPPER VOLVAGE EFFICIENCY OF LANDSCAPE-ADAPTED TECHNOLOGIES OF CULTIVATION OF FLAX OIL-DIVIDED
The article presents the results of a three-year experimental study of the efficiency of growing flax oil-bearing inter-grade cultivar (v. Intermedium). The studies were conducted simultaneously in four areas: in geotopes of sandy and moraine landscapes with automorphic and semi-hydromorphic soils, typical of the arable land of the region and contrasting in a complex of agroecological properties. Tested technologies of different intensity levels. The intensification factor is the fertilizer system. The ability of the culture to form the highest and most stable yields of seeds and straw on automorphic medium loamy sod-podzolic soils of the plakorny range of the moraine landscape is revealed. Crops on the soils of the sandy landscape are lower and unstable. In the hollow area of the moraine landscape with gleyic soils in years with abundant precipitation during the period of ripening on a high agricultural background, there is a disproportion in production processes to the detriment of seed and oilseed productivity.
