USE OF MICROBIAL PREPARATIONS AND HUMICS FERTILIZER FOR EGGPLANT GROWING IN FILM GREENHOUSES

Abstract

A promising direction of modern vegetable growing under organic cultivation approaches is the use of microbial preparations and humic fertilizers to optimize plant nutrition, stimulate growth processes and increase yields of high standardized quality. The purpose of the study is to establish the effect of using microbial preparations and humic fertilizers for growing eggplant in film greenhouses without additional heating. Methods. Field, computational and statistical. The results. The influence of microbial preparations of various directions and humic fertilizers on the biometric parameters of plants, productivity and yield of eggplant during its cultivation in the conditions of film greenhouses was investigated. A significant increase in leaf area was noted both in the phase of mass flowering and in the phase of mass fruiting with the use of all microbial preparations Phosphoenterin, Ecobacil, Bactopaslion and ABT. The greatest increase in the net productivity of photosynthesis of eggplant plants is provided by the use of the preparations Ecobacil and Bactopaslion (7,14-7,79 g/m2 per day). Conclusions. For the cultivation of eggplant in film greenhouses without heating, the use of microbial preparations Phosphoenterin, Ecobacillus, Bactopaslion and ABT is effective, which ensures an increase in leaf area by 17,5-48,6 %, photosynthetic productivity by 31,4-56,2 % and productivity by 0,98-3,26 kg/m2 or 16,1-47,7 % depending on the background of mineral nutrition. The use of humic fertilizers ("Nanoverm", "Gumifriend", "Gumifield") under foliar fertilization in 4 seasons led to a significant increase in plant height by 32,4-49,0 %, average fruit weight by 4,3-9,5 % and productivity by 0,87-1,73 kg/m2 or by 11,8-23,4 % relative to the control. A high level of productivity is indicated for the use of "Gumifriend" and "Gumifield" fertilizers.
