Effect of microbiological agents on spring barley cultivated in the north of the Astrakhan region

Abstract

The aim of the study was to determine effectiveness of the use of microbiological agents in spring barley cultivation. The experiments were conducted in the conditions of light chestnut soils in the north of the Astrakhan region, Chernoyarsky district, Solenoe Zaymishche village in 2018-2020. The use of this cultural method contributed to two-fold increase in the productivity of spring barley (3.5 t/ha), compared with the control (without any seed treatment - 1 .4 t/ha). The pre-sowing inoculation of seeds increased field germination and number of mature plants: by 75 and 26.8 % for Mizorin, 79 and 40.9 % for BisolbiFit, 78 and 37.6 % for Rizoagrin, respectively, in comparison with the control. Application of these microbiological agents in spring barley cultivation can be recommended to both small and large farms, which will help to rise the agriculture of the region to a high level of production of spring barley.
