Abstract

One of the main directions of intensification of the feed production industry is the cultivation of fodder crops and forage harvesting from them based on the use of economically feasible and energy-saving technologies. The aim of the research was to determine the influence of mineral fertilizers and seed inoculation on the economic and energy efficiency of sainfoin growing technology on green fodder. Experimental studies were conducted during 2016-2018 on the research field of the Department of Forage Production, Land Reclamation and Meteorology, located in the NULES of Ukraine "Agronomic Research Station" on typical low-humus chernozem. According to the results of the research, it is established that for growing sainfoin for green fodder the most profitable (176 %) is the variety Amethyst Donetskyi in the absence of fertilizer, however, application of mineral fertilizers in the dose N45R60K90 in combination with seeds inoculation by Rhizotorfin significantly increases crop yield, and the net profit. The best in terms of energy efficiency and energy efficiency ratio was the technological model of growing this variety of sainfoin, which did not provide for the application of mineral fertilizers or the application of only P60K90
