EFFICIENCY OF ACCELERATED RESTORATION OF LOW- PRODUCTIVE PERENNIAL FORAGE LANDS

Abstract

The development of sheep and cattle breeding in the Stavropol Territory requires the creation of a good fodder base, the development of which is impossible without improving the

natural forage lands, which remain the main source of green fodder balanced in all nutrients. However, recently the productivity of such lands has significantly decreased due to an in-crease in the load on them, lack of care and unsystematic use. In this regard, the use of tech-nological methods and growing techniques aimed at increasing the productivity and efficiency of natural fodder lands using low-cost methods of improving them will quickly increase the yield of such phytocenoses. Studies on the accelerated restoration of low-productive perennial fodder lands were carried out in 2013-2018 (laying in 2013 and 2014) in the Agricultural Pro-ductive Cooperation of the Druzhba Breeding Plant in the Apanasenkovsky district of the Stavropol Territory in extremely arid zone. It was established by experiments that the use of surface improvement increases the production costs of total energy by 1,38-2,38 times, but they are more than offset by an additional crop, 1,9-2,5 times lower unit costs, and 57,0-92% higher production profitability. The total 5-year costs that were allocated for the implementa-tion of the proposed technology exceeded the costs on the control variant without improving the grass stand by 1,93-2,52 times, however, due to the additional crop, 5 year worth of prod-ucts were obtained in the amount of 56,0-86,4 thousand rubles, the cost of 1 ton of production fell from 2801,8 to 2156,8-2704,8 rubles.
