Abstract
In the dry steppe and semi-desert zones of the Lower Volga region, under irrigated conditions, annual forage crops were studied on zonal soils of the Volgograd region, and in the dry steppe zone of the Republic of Kalmykia, a complex of problems regarding the technology of growing sorghum crops is poorly understood [1,2].
The research results confirm that when growing sorghum crops using a system of two or three harvests, the coefficient of arable land utilization increases to 1.1...1.3, it is possible to obtain 100...150 t/ha of green mass and increase the productivity of an irrigated hectare to 15 thousand feed units and more [3].
Monitoring the state of fertility of agricultural lands on the territory of the Republic of Kalmykia is carried out by the Federal State Budgetary Institution SAS “Kalmytskaya”. The content of mobile phosphorus and potassium compounds is determined by the Machigin method modified by TsINAO (GOST 26205-91), humus by the Tyurin method modified by TsINAO (GOST 26213-91), mobile sulfur by the TsINAO method (GOST 26490-85), microelements – according to approved methods [4].
