Dependences of the yield of common beans on agrotechnical factors in the zone of chestnut soils of the Astrakhan region

Abstract

The article presents the results of agroecological study of the common bean collection, not only under the conditions of the subtype of light chestnut soils of the Astrakhan region, but also worked out the mode of irrigation of this crop, inoculation of seeds with rhizotorphin on a drip irrigation method. The need for research was primarily due to the insufficient number of bean varieties ideally adapted to the specific climatic conditions of the region, which is associated with insufficient study of both the morphology and biology of the culture. As objects of study, a test culture of beans and the drug rhizotorfin were chosen. The study showed that when cultivating common beans under irrigated Astrakhan region in the subzone of light chestnut soils, it is advisable to carry out pre-sowing inoculation of seeds with rhizotorphin, which ensures a stable yield of common beans on drip irrigation, and also contributes to the accumulation of biological nitrogen. Thus, based on the data obtained, on drip irrigation in the subzone of light chestnut soils, it is economically feasible to sow in a wide-row method (0.70 m) with a seeding rate of 500,000 germinating seeds per hectare and carry out pre-sowing seed inoculation with rhizotorphin.
