Soil salinity management on raised beds with different furrow irrigation modes in salt-affected lands
Mismanagement of irrigation water and the ensuing secondary salinization are threatening the sustainability of irrigated agriculture especially in many dryland regions. The permanent raised-bed/furrow system, a water-wise ...
An agronomic, economic and behavioral analysis of N application to cotton and wheat in post-Soviet Uzbekistan
Cotton and winter wheat play a vital role in Uzbek agriculture: the first crop is a vital component of the national export revenues, while the latter is key in achieving independence from grain imports. Due to these strategic ...
Farm Restructuring and Land Consolidation in Uzbekistan: New Farms with Old Barriers
In this article we investigate the potential for and limitations of land consolidation as a tool for rural development in transitional environments, focusing on the Khorezm region in Uzbekistan, Central Asia. We frame our ...
Combining permanent beds and residue retention with nitrogen fertilization improves crop yields and water productivity in irrigated arid lands under cotton, wheat and maize
Intensive soil tillage and mismanagement of irrigation water and fertilizers are increasing production costs, reducing soil fertility and crop water productivity and threatening the sustainability of crop production systems ...
Managing soil salinity with permanent bed planting in irrigated production systems in Central Asia

Tillage and nitrogen fertilization effects on yield and nitrogen use efficiency of irrigated cotton
Management practices may influence yield and nitrogen (N) use efficiency of irrigated cotton (Gossypium hirsutum L.) in irrigated arid lands such as those of the Aral Sea basin. A field experiment was conducted to compare ...
Simulating water use and N response of winter wheat in the irrigated floodplains of Northwest Uzbekistan
The crop-soil simulation model CropSyst was used to simulate growth, water- and N-uptakes of irrigated winter wheat (Triticum aestivum L. cv. Kupava) in Khorezm, in the dry lands of northwest Uzbekistan, Central Asia. ...
Reducing topsoil salinity and raising carbon stocks through afforestation in Khorezm, Uzbekistan
Agricultural mismanagement of irrigated drylands results in severe soil degradation Afforestation is an option for ameliorating such degraded land We evaluated the impact afforestation has on the topsoil (0-20 cm) of ...
