EFFICIENCY OF THE TECHNIQUES OF PROTECTION OF ALFALFA FROM WEEDS AND METHODS OF ITS SOWING WITH AND WITHOUT A COVER CROP
Abstract
The productivity of alfalfa was studied on cohesive sandy soil in 2019-2020 with the application of different techniques of sowing and protection from weeds. It was established that sowing alfalfa after harvesting winter rye for green mass with further disking, harrowing and rolling allowed managing without herbicides and obtaining 215.5 dt/ha of dry matter for 2 years totally. At the same time when sowing alfalfa in spring after autumn plowing and applying the herbicide Rodimich, 1 l/ha or the tank mixture (Rodimich, 0.75 l/ha + Bazagran, 1.5 l/ha), the yield was 149.1-150.6 dt/ha, and without a herbicide protection it was even less - 130 dt/ha. Even planting alfalfa to winter rye to be harvested for green mass, as well as direct sowing after harvesting rye for green mass without the application of herbicides showed a higher total yield of dry matter, amounting to 172.8–192.8 dt/ha.
