Tomakh I. Energy efficiency elements of table beet seeds growing technology with drip irrigation in the left-bank forest-steppe of Ukraine.

Object: regularities of formation of high yield and seeds quality of table beet Purpose: Development of energy efficient technology elements of growing queen cell roots and seeds of table beet. Novelty: first for the terms of left-bank forest-steppe of Ukraine has established formation patterns of crop of queen cell roots and seeds of table beet of regulatory quality when grown with drip irrigation. Studied the influence of these elements on yield and output of queen cell roots of standard fraction and of roots-shteklings. Found the best way of irrigation and mineral fertilizer application while growing queen cells and seed plants. Determined the dynamics of nitrogen, phosphorus and potassium content in the soil during the growing season, and also established the effect of technology elements on consumption of feeding elements by plants. Demonstrated the influence of irrigation and the size of queen cell roots on changeability of seed bush architectonics and on the nature of seed plant root system development in the soil profile. Constructed the regression equation to calculate important parameters of energy efficiency. Noted preservation of varietal and economically valuable characters of table beet plants in generations. Results: The developed energy-efficient technology elements are confirmed in manufacturing conditions of Novovodolazkii and Kharkivskii districts of Kharkivska region which give yield of table beet seeds at the level of 1,51-1,72 t/ha, profit - 58,3-67,5 thousand UAH/ ha, self cost of 1 kg of seeds - 30,8 UAH.
