Abstract

In order to check the possibility of using electrochemically activated water (ECHAW) in irrigation, a study was conducted to determine the influence of anolyte on biological pollutants of wastewater and the reduction of water mineralization by electrochemical activation, as well as the influence of catholyte and anolyte on the germination of seeds of cereal crops, the development of seedlings of pepper and tomato, and the yield of tomato. The research was conducted in laboratory conditions on two varieties of pepper and four varieties of tomato. ECHAW was obtained using laboratory water activators of our own production. Wastewater samples were taken at the Bortnychy wastewater aeration station in Kyiv. Experiments were carried out using vegetation containers of various types and one-time bacteriological tests. It was found that by electrochemical activation of mineralized water it is possible to reduce the level of its total mineralization by more than 50% and, with an anolyte, to destroy disease-causing bacteria in wastewater. The use of ЕCHAW accelerates the germination of seeds of cereal crops. On the 3rd day of germination, wheat grain germinated using EHCAW has a 9% longer root length than the grain germinated under the same conditions using non-activated water. Wheat grain germinated using EHCAW also has 33% longer sprouts. The growth rate when irrigated with activated water, depending on the variety of tomato plants, increases by 9,8-25,2%, the increase in stem diameters was equal to 11,3-22,4%. The yield of tomatoes when irrigated with activated water is 12,6-15,8% higher than in the case of irrigation by ordinary water, the size of the fruits is 15,4-25,1% larger. The results of the conducted research indicate the possibility and perspective of using EHCAW to increase the yield of crops under irrigation and improving the quality of drainage and wastewater by reducing their mineralization and providing their disinfection.
