The article reflects the results of a study on the study of the economic and energy efficiency of growing crops in irrigated tilled crop rotations under various basic tillage and fertilizer systems in the southern Ukraine.
The aim of the research was to establish economic and energy indicators of technologies for growing crops in irrigated tilled crop rotation with a change in basic tillage and fertilizer systems in the southern Ukraine. The task of the study was to determine the influence of the factors studied on the economic and energy indicators of irrigated crop rotation to create new and improvements methods and systems for basic tillage and fertilization.
Field experiments were carried out according to the techniques of an experienced case. Agrotechnics of cultivation of investigated agricultural crops in irrigated crop rotation was generally recognized for the conditions of the south of Ukraine.
It was established that a high conditional net profit (8.3-10.0 thousand UAH) per 1 ha of crop rotation area with a profitability level of 99.8 and 109.8% ensured the application of a differentiated soil treatment system with two fertilizer systems. An assessment of the energy efficiency of fertilizer systems indicates that the doses of nitrogen fertilizer and the use of microbial preparations for inoculation of soybean seeds, which ensure the growth of crop rotation productivity by the output of gross energy, and thereby increase the energy coefficient by 0.4. When growing various biological properties of agricultural crops, replacing the dump and non-bottomless, non-deep processing for systematic small loosening leads to a decrease in the productivity of crop rotation.
Taking into account the urgency of the research direction, it is planned to study the efficiency of the application of various basic tillage and fertilizer systems in crop rotations with drip irrigation.
