The impact of farming practices on the productivity of soybean

Abstract

The article describes research results of agroecological factors set, their impact on the productivity of soy and reactions to them of modern varieties in the western forest-steppe zone of Ukraine. Compositions of microorganisms which enable to accelerate the growth and development of plants, reduce the spread of disease, increase productivity and improve product quality were used. The influence of green manure on the growth and development of soybean plants was investigated. The positive effect on the crop capacity and quality of soybean seeds, when at the crop flowering stage spraying the microbial preparation Hetomik based on strain Chaetomium cochliodes, was established. Different reactions of studied soybeans varieties were found. The most sensitive to factors of influence were varieties of Georgiana and Angelica. The plants of these varieties have formed larger amount of beans, high-quality seeds, nodules on the root system, area of a leaf surface and increased weight nodules on the roots of one plant and weight of 1000 seeds. It was established that in western forest steppe zone seeds of soybean varieties were appropriate to make Inoculation of rhizobia strains 634B and M-8 before sowing on the background making to the soil green manure. Crops of specified varieties are recommended to spray in the flowering stage with biopreparation Hetomik at a dose of 100 ml/ha, using a working solution of 250 l/ha
