Abstract

Yield and quality of seeded cereal and bean-cereal pastrases of alas meadows northern zone of Yakutia.

Abstract

At present, the main problem of livestock breeding in the republic is the low productivity of livestock, the reason for which is the low feed supply. The main production of rough and succulent fodder in Yakutia is concentrated on natural hayfields and pastures. Therefore, the study of the yield and quality of seeded cereal and legume-cereal pastures of alas meadows is an urgent problem for Yakutia. The experiments on the yield and quality of seeded cereal and legume-cereal pastures of alas meadows were carried out in 2010-2012. on the site «Namta5ai» s. Horobut of Megino-Kangalassky ulus. To create cereal and bean-cereal grass stands, regionalized varieties were used: beef less rump Ammachaan, calyx bush grouse Bootur, Siberian grassroot Amginsky, crescent yellow alfalfa Yakutskaya. In the experiment, 7 variants of cereal and bean-cereal grass stands in three repetitions: natural grass control - control, gingerbread grouse, Siberian grass grass, beetroot boneless, grouse + bonfire + wheat grass, sickle alfalfa, alfalfa + crowberry + rump. Mode of use - imitation of grass grazing as pasture ripeness occurs. The highest productivity of pasture fodder for two cycles of use from cereal grass stands was formed by a three-component of brittle grate (8 kg/ha) + crust (20 kg/ha) + grassland (16 kg/ha) - 98.9 c/ha, Siberian wheatgrass - 39.8%, grouse - 35.7%, boneless rump - 23.7%, established species - 0.8%. Of the leguminous-cereal grass stands, the highest productivity is provided by alfalfa (6 kg/ha) + gritter (6 kg/ha) + crust (15 kg/ha) - 97.5 kg/ha, the proportion of alfalfa in the grassland is 28.7%, and the grit-tree 35.3%, boneless rump - 34.4%, introduced species - 1.6%. High nutritional qualities in the first and second pasture feed from cereal grass mixtures are provided by the grouse, crowberry grate + bonfire + wheat grass, gritty grate + bonfire + wheat grass, from legume-cereal mixtures pure sowing of alfalfa and alfalfa + gritty + bonfire.
