EFFICIENCY OF MICROBIAL PREPARATIONS IN TECHNOLOGY OF TOMATO GROWING
Journal Title: Наукові доповіді НУБіП України - Year 2017, Vol 6, Issue 6
Abstract
Microbial preparations and bioorganic fertilizers based on them provide improvement of mineral plants nutrition, stabilization and reproduction of soil fertility, promote increase of yield and obtain of high-quality production of plants. In recent years, the market is filled with a variety of biologics, but specific recommendations for their use for various crops, including tomato, are absent. The aim of research was to determine the efficiency of using microbial preparations and bioorganic fertilizers in the system of optimization of tomato nutrition in conditions of the Left bank Forest-steppe of Ukraine. The research was conducted in the laboratory of agrochemical research and quality of products in the Institute of Vegetables and melons growing NAAS on typical low-humus chernozem during the 2013-2015 years. It was determined that the use of microbial preparations ABT, Biogran, Azotofit promote the increase of the content of mobile nitrogen compounds (by 11,4-24,4 %) and partially phosphorus (by 13,5-17,6 %) in the arable soil layer, increasing the amount of nitrogen fixation bacteria in the rhizosphere layer of the soil (to the level of 6,85-7,45 m/g of dry soil) and increase of the potential activity of nitrogen fixation (22,08-26,5 C2H2/g of dry soil per hour). At the same time there is an increase of the total yield of tomato by 18,3-22,8 %. Marked microbial preparations can be used later for the formation the systems of optimization nutrition of vegetable plants in the technologies of organic cultivation.
