Efficiency of cultivation of intermediate cover crops as a biological element of the fertilizer system at no-till in the Crimea

Abstract

The aim is to create the fundamental biologization’s components of no-till system in the environment of foothill-steppe Crimea’s area, to explore the effect of different kinds of cover crops on the indications of soil fertility, on the crop productivity and on the seeds’ quality of the agricultural crops in terms of poor and unstable humidification. During the cultivation of the cover crops in no-till system the reserves of available humidity in the thickness of one metre were acceptable after the growing of vicia – 107,6 millimeters and on the control (without the cover crops) – 99,6 millimeters. The least reserves of available for the plants humidity were in the option with winter rape, as in pure form (59,3 millimeters), as in combination with vicia (44,9 millimeters). The highest crop productivity of cover crops’ green mass was in all cases with the using of the multicomponent combination. It exceeds the crop productivity of the cover crops consisting of 1-2 and 3 sping crops more than twice as much and almost more than 10 times – the crop productivity of the winter rye.
