The efficiency of combined use of inoculation and EM-technologies in the cultivation of legumes

Abstract

The article deals the problem of creation of new multifunctional microbial preparations with nitrogen-fixing, growth-stimulating and bioprotective properties to increase crop yields and referring to the issue of obtaining high quality products and improving the environment, the use of nitrogen-fixing simbiotrof with EM-preparations (from EM – effective microorganisms). The results obtained during the research enable us to suggest a combined treatment of Phaseolus vulgaris Nadiya and Glycine max Annushka in soil and climatic conditions of Ukraine Forest-Steppe with EM-fertilizer «Baikal EM-1U» and the inoculation of nodule bacteria Rhizobium phaseoli strain 700 and Bradyrhizobium japonicum strain 634b of seeds as a perspective tendency of crop productivity growth (increased the yield by 3,6-10,0 cwt/ha) and nitrogen-fixing. Presowing treatment of white lupine seeds (variety Makarivskyi) with fertilizer «Baikal EM-1U» in combination with nitrogen-fixing bacteria Bradyrhizobium sp (Lupinus) strain 367a contributed to the branching of the stem, the growth of leaves on the plant, increased chlorophyll a content, increased mass of nodules on the roots and their nitrogen activity.
