Kvitko G. The scientific crowds and working out of intensive agrotechnical methods of rising of fodder productivity of Lucerne in forest steppe of Ukraine

Lucerne. Alfalfa (Medicago sativa), early and late spring crops. To establish a relationship between the agroecological conditions of alfalfa growth and development in the year of sowing and next yers. Research methods- field method, zootechnical feeding, estimate. The considerable advantege of the spring type of alfalfa development in the year of sowing for obtaining maximum productivity during next years of vegetation is theoretically substantiated. Crop rotation links with the spring type of alfalfa development ensure the heavier feed unit yield by 32,4-40,6 per cent and protein one by 64,9-76,2 per cent as compared with a link grain barley - alfalfa two yers . The improved alfalfa growing technology is early introduced in the collective agricultural enterprises over the area 150-170 thon.ha. The reduction of corts when growing by 12-15 per cent. Collective enterprises and farms.
