Abstract
The important role in intensification and biologization of fodder production is played by the cultivation technology and the use of different plant formations.At that, the particular interest is paid to intense species and varieties of perennial legumes, and primarily, alfalfa.Therefore, we selected Kapchagai 80 variety of alfalfa differing by suitability for hay-pasture use.In the experiments on the study of the biologization and soil cultivation techniques for alfalfa sowing, in the most successful options we obtained high yields of hay with the highest protein content; plus minimum cultivation and seed treatment with nitragin at a rate of 50 grams/kilogram that had a favorable impact on the improvement of soil fertility.The conducted research revealed a significant effect of agricultural background and biologization on the productivity of alfalfa, where the yield increase amounted to 21.3-26.4hundredweight per hectare (hwt/ha).
