Evaluation of Economic Efficiency of using Resource Saving Technologies (Conservation Agriculture) in Irrigated Lands

Abstract

Global climate change, reduction in planting areas, land degradation, limited water resources, and ecologic problems influence food security directly. The role and importance of resource saving technologies (conservation agriculture) is increasing considerably high in intensive development of agriculture of Uzbekistan. The objective of the research is economic evaluation of wheat production under conservation agriculture practices in irrigated lands. Economic indicators show that winter wheat production under conservation agriculture is more efficient than under conventional agriculture practices. For the purpose of economic evaluation of conservation and conventional agriculture practices, full costs and profit are taken for winter wheat production. Under resource saving technologies (conservation agriculture) in 1 ha, fossil fuels are saved by 53%, and economic efficiency is 1141825.8 ($ 456) sums.
