ACTIVITY OF NITROGEN FIXATION IN LUCERNE AGROCENOSES AND PRODUCTIVITY OF CULTURE UNDER INFLUENCE OF FERTILIZERS AND MICROBIAL PREPARATION
Journal Title: Сільськогосподарська мікробіологія - Year 2017, Vol 25, Issue
Abstract
In a long field experiment on common black soil, the influence of various fertilization systems and presowing bacterization of seeds on the activity of symbiotic nitrogen fixation in lucerne agrocenoses and crop productivity was studied. Stimulation of the process of fixation of atmospheric nitrogen was observed when mineral fertilizers were used in the doses not exceeding N60P60K60, when they were introduced in the year of sowing. High rates of nitrogenase activity were noted in conditions of aftereffect of manure, compost, organic mineral fertilizer (manure + N30P30K30), as well as systematic use of crop residues in the crop rotation. The plant mass in above variants was characterized by high protein content. At the same time, the greatest influence on protein synthesis was provided by the use of a microbial preparation. The combination of ecologically acceptable agricultural backgrounds with presowing bacterization of lucerne seeds ensured the obtaining of parameters of crop productivity.
