IMPROVEMENT OF THE SCIENTIFIC BASICS OF ARID AGRICULTURE OF BURYATIA

Under the conditions of the dry steppe of Buryatia, the productivity of the traditional 4-field grain-fallow crop rotation is determined, first of all, by the hydrothermal index for May-August and the use of nitrogen fertilizers. Grain crops are inferior in agroeconomic assessment to the cultivation of the terminal feed crop, which predetermines the adjustment of existing crop rotation schemes. Spring rye should be considered as a guarantor of the stability of the development of agricultural production in arid agriculture in the region.
