ECONOMIC ASSESSMENT OF HAY MULCHING TECHNOLOGY, APPLIED IN SYRDARYA PROVINCE IN UZBEKISTAN

Abstract

Syrdarya province is one of the regions of Uzbekistan most affected by land degradation. Insufficiency of fresh water resources is the main constraint for agricultural development in the province. In this regard, using the technology of mulching and waters with different salinity levels is one of the appropriate technologies being implemented at this region. Mulching is a well-known soil improvement measure. It is effective in improving soil physical properties by reducing water runoff and increasing water infiltration. It also protects the soil against raindrop impact, preventing soil crusting and contributing to soil organic matter and nutrients. Application of hay mulch to soil can reduce tail water generation at the field level and thus increase water use efficiency. This paper shows the results of socioeconomic feasibility analysis of implementing this technology at the experimental site of Uzbek Research Institute of Cotton Growing at Syrdarya province.
