The article explores the possibility of using scientific principles for the creation of highly productive agrophytocenoses with given parameters in the system of rainfed farming in the North-Western Caspian region. For pasture agrophytocenoses, created in the dry farming of the arid zone, until now there has not been developed a sufficiently complete theoretical and practical basis. In general, the theory and practice of creating agrophytocenoses with given parameters was developed for field crops and crops under irrigation conditions. Therefore, we made an attempt to substantiate theoretical principles and practical recommendations for the creation of pasture agrophytocenoses with given productivity parameters in conditions of rainfed farming. These principles boil down to the following: the biological principle; agrochemical principle; agrophysical principle; agrometeorological principle; agrotechnical principle. The theoretical and practical foundations for the creation of pasture agrophytocenoses with a given productivity of 2,0-3.7 t / ha dry weight in dry farming in the arid zone of the North-Western Caspian are formulated. The influence of a complex of agrotechnical measures on the achievement of a given productivity of pasture agrophytocenoses in the system of rainfed farming was studied, and a technological map (network schedule) of timely fulfillment of all agrotechnical measures for a productivity of 3,7 t / ha dry weight was compiled.
