Effectiveness of microbial preparations in growing Cicer arietinum L. in the steppe zone of the Crimea

Currently, the main priorities in agricultural production are ecologization, rational use of natural resources, resource-conservation and economic practicability. Therefore, biotechnologies for growing agricultural crop develop. The article presents the results of effectiveness of pre-sowing treatment with polyfunctional microbial preparations compared to the use of mineral fertilizer Ammophos in growing Cіcer arіetіnum L. in the steppe zone of the Crimea on non-irrigated southern Chernozem in 2015-2017. Weather conditions during the growing season and treatment with microbial preparations, as well as the use of mineral fertilizers, affected seed productivity of chickpeas in the time of research. On average, for three years, bacterization with Rhizobofit, Cyano-rhizobial consortium and complex Rhizobofit + Phosfoenterin + Biopolicyd significantly increased 1000 seeds weight and seed yield by 16.67 g (6.7%) and 0.15 t/ha (10.8%); 27.27 g (9.8%) and 0.1 t/ha (7.2%); 14.14 g (5.5%) and 0.22 n/ha (15.1%), respectively, compared to the Ammophos application in dose N30P30 (Duncan’s test p < 0,000121). These preparations are recommended for biologised agrotechnology for growing chickpea in the steppe zone of the Crimea and obtaining ecologically safe production.
