Zhuravlev O. Influence of drip irrigation, plant density and micronutrient fertilizers on the productivity of onions in the Southern Steppe

Object of researches - products processes of plants of bow of the turnip sort Chalcedony at different modes of tiny irrigation, density of plants and action of mikrofertilizer Baykal of EM-1У. Purpose of researches - to set influence of the mode of tiny irrigation, density of plants and mikrofertilizer Baykal of EM-1У on productivity of bow of turnip in South Steppe of Ukraine. Methods of researches - the field; laboratory; statistical; computation-comparative. Results of researches: 1. For a theory - For the terms of South Steppe of Ukraine the mode of tiny irrigation is improved, optimum density of plants is definite, first in South Steppe the influence of mikrofertilizer Baykal of EM-1У on productivity of bow of turnip is explored. Acquired subsequent development of determination of average daily evaporation of bow of turnip, conformity to the law of forming of areas of moistening depending on different levels of humidity of soil. 2. For practice - On the basis of results of researches for the terms of South Steppe of Ukraine the scientific-grounded elements of technology of growing of bow of turnip at tiny irrigation are offered, which provide the receipt of productivity at the level of 70 t/ga. The sphere of the use is the agricultural enterprises of south of Ukraine.
