Economic and energy efficiency of onions depending on the conditions of moisturizing and protection
Journal Title: «Таврійський науковий вісник» - Year 2018, Vol 99, Issue
Abstract
In the article results of researches on an establishment of economic and power efficiency of technology of cultivation of onion are reflected depending on irrigation regimes and schemes of protection of plants from pathogens at cultivation of culture in system of drop irrigation in the south of Ukraine. According to the results of the research, it has been established that the best results are achieved by the use of the drip irrigation method with observance of the irrigation regime of 80% NW in the 0.5 m layer and the chemical protection of plants from pests and pathogens with an integrated scheme. Economic analysis proved that the maximum net profit at the level of 37.7 thousand UAH/ha with a profitability of 129.3% was obtained when growing onions with irrigation regime with a pre-determined threshold of 80% NW against the background of chemical plant protection. The minimum energy intake was at the irrigation regime of 70% NW and without the use of biological and chemical means of plant protection. The highest energy coefficient was on options with watering 70-80% NW and using chemical plant protection.
