THE ROLE OF THE BACTERIA PREPARATIONS AND GREEN MANURE IN BIOLOGICAL CULTIVATION OF POTATOES
The article deals with the research in micro-field experiment that studied the aftereffect of green manure crops, manure and biological product «Agrika» on the microbiological properties of soil, yield productivity and quality of potato tubers. It was stated that green manure pairs positively influence the microbial composition of the soil. The aftereffect of green manure mass contributed to increasing the total number of cellulose-decomposing microorganisms compared to the control variant. When treating potatoes with bacterial product «Agrika» it stimulates metabolic processes, changes the speed of the initial growth reactions, accelerates the formation of the leaf surface and activates the processes of photosynthesis. By the period of formation of the maximum leaf surface the joint action of the bacterial preparation and the aftereffect of organic fertilizers had increased leaf surface area, not only in comparison with the control variant, but also in comparison with the background 1 without an inoculation. The use of «Agrika» inoculation strengthens the aftereffect of manure and green manure and increases the yield and quality of potato tubers.
