Scientific coverage of stable agricultural production under conditions of growing climate aridization

Main tendencies of climate change and the factors (absence of insurance mechanisms of adaptation, distortion of the crop area structure, reduction of the agrochemical load, simplification of the technological designs) leading to yield decrease were revealed by the method of long-term monitoring of the agroclimatic indices of the Povolzhye region of Russia. The criteria of stable grain yield are also determined: creation of new generation varieties resistant to abiotic and biotic factor of the environment based on the new breeding methods (biogeocenotic, symbiotic, phytocenotic), agrolandscape arrangement of the area, and precision agriculture using the ridge-coulisse technologies.
