Environmental, economic and energy efficiency of soil tillage systems in crop rotation under irrigation

Abstract

Applying the systems of mold-board (with different depths) and differentiated primary soil tillage under irrigation conditions and using agricultural implements with different designs of working elements facilitate implementation of the potential yielding capabilities of the varieties and hybrids of agricultural crops and provide the produc-tivity of crop rotation at the level of 82.0-82.2 GJ/ha (the output of gross energy). The highest environmental and economic ef-fect, taking into account monetary and energy assessment of increase of humus reserves (0.81-1.02 t/ha per year, or 20.3-21.9 GJ/ha) was observed in the options with different tillage depths and differen-tiated systems of primary soil tillage and amounted to 42.9-43.6 thousand UAH.
