Effect of sowing type and irrigation method on productivity of legume-bluegrass mixtures under multiple cutting

Research objective was to study influence of various irrigation methods and sowing types on productivity of legume-bluegrass mixtures under multiple cutting. Effect of irrigation methods on productivity of different perennial forage grasses grown in light brown soils of Northern Caspian region was studied for the first time. The experiment had two factors - forage grass mixtures ( Agropyron pectiniforme , Trifolium pratense , Phleum pratense , Festuca pratensis ; 25 : 25 : 25 : 25) and various methods of irrigation. Records and observations were made according to the practical standards of B.A. Dospekhov, I.N. Beydeman and the Study guide on mobilization of vegetable resources and introduction of arid fodder plants of Williams Fodder Research Institute. The two-year research resulted in the following conclusions: widespread sowing turned out to be far more effective compared to drilling and was 40.9 t/ha higher; grass yields under flooding were the lowest in all sowing variants and differed insignificantly - 55.6 t/ha in drilling and 55.2 t/ha in widespread sowing.
