Shcherbakova O. Chickpea productivity and activity of their legume-Rhizobium system depending on pre-seeding treatment on Right-bank Forest Steppe of Ukraine

Dissertation is devoted to improving of cultivation technology and to studying the agrobiological foundations of chickpea on the Right-bank Forest Steppe of Ukraine. For the first time the chickpea productive potential was studied in conditions of Right Bank Forest Steppe of Ukraine, the features of formation of yield and seed quality was established for typical chernozem and depending on the biopreparation of nodule bacteria and colloidal solution of molybdenum pre-treatment. Efficiency of the plant-bacterial systems based on the variants of treatments by nodule bacteria and colloidal solution of molybdenum. The plant productivity of chickpea and composition of yield structure elements was measured. The features of formation of chickpea grain quality was studied depending on the pre-treatment of seeds. The content of essential fatty acids and protein in the seeds was determined. The economic and energy efficiency technology of chickpea cultivation on the Right Bank Forest Steppe of Ukraine was calculated. For the first time in Ukraine the compositions of biopreparation based on the high-efficient strains of endophytic and rhizospheric bacteria and microelements in the form of the colloidal solution of biogenic metals was created. The optimum parameters of formation and structure elements of chickpea yield was determined: the overall survival, density of plants, the number beans, length of bob, number grains on the plant, mass of 1000 grains. The relation between structure elements yield and ways of adjusting their parameters was established.
