Influence of sowing time on productivity and nutritional value of the sudanese grass in the conditions of the Central Yakutia

Abstract

The Sudanese grass is one of the most valuable annual fodder herbs of family of cereals. The drought resistance, high productivity, high quality of green material and hay, ability to grow quickly after beveling or drain, big and steady crops of seeds, - all this factors allow expanding seeds, promote rapid implementation of this culture in production making it one of the most valuable one-year forage crops. The Sudanese grass combines high efficiency and fodder advantages with drought resistance and ability to use a maximum of rainfall of the second half of summer that are common to our climate. For the first time the productivity and nutritional value of a Sudanese grass for preparation of juicy forages under the conditions of the Central Yakutia is studied. According to researches the studied sowing time is capable to form to 19.4-26.3 t/hectare of green material when beveling on juicy forages. From all three studied sowing time the best is the II sowing time (on June 15). High rates on productivity are observed in the second sowing time, at the same time the maintenance of a digested protein in 1 kg of SVmade 178 g, 0.67sterns. piece.
