SYMBIOTIC NITROGEN-FIXING ABILITY OF CHICKPEA AND PRODUCTIVITY OF CROP AT DIFFERENT FERTILIZATION
Journal Title: Сільськогосподарська мікробіологія - Year 2017, Vol 25, Issue
Abstract
Results of studying effect of mineral fertilizers in combination with inoculation with nitrogen-fixing bacteria on chickpea productivity in podzolic black soil of Right-Bank Forest-Steppe of Ukraine have been shown. Pre-sowing bacterization contributed to the active formation and functioning of the symbiosis, provided that the background of nitrogen fertilizers did not exceed 60 kg/ha. Under the influence of mineral fertilizers both separately and in combination with seed inoculation, chickpea yield increased by 10.8–15.2 hwt/ha compared to the variant without fertilizers and without inoculation. It was established that in order to obtain high and stable yields of chickpea seed in podzolic black soil of Right-Bank Forest-Steppe of Ukraine with low content of nitrogen of alkalihydrolyzing compounds and high content of mobile phosphorus and potassium, its fertilization system should include application of phosphate and potash fertilizers in the dose of 60 kg/ha during primary tillage, and nitrogen fertilizers – for presowing cultivation. Before sowing, seeds should be processed with the suspension of ammonium molybdate and Ryzobofit.
