Virulence of Pyrenophora tritici-repentis in the countries of the Silk Road
Tan spot, caused by the fungal pathogen Pyrenophora tritici-repentis, is an important foliar disease of wheat. Eight races of the fungus are presently known based on their virulence on a wheat differential set. In 2001, ...
Coupling hydrological and irrigation schedule models for the management of surface and groundwater resources in Khorezm, Uzbekistan
The irrigated agriculture in the Khorezm region of Uzbekistan is characterized by huge water
withdrawals from the Amu Darya River. The vast infrastructure built for extensive irrigation,
together with inappropriate drainage ...
Conversion Factors to Estimate Soil Salinity Based on Electrical Conductivity for Soils in Khorezm Region, Uzbekistan
This paper compares different procedures for soil salinity analyses to determine
electrical conductivity: saturated paste extract (ECe), xed soil:water
ratio extracts EC1:1 and EC1:5, and soil solution paste prepared with ...
Improving wheat stripe rust resistance in Central Asia and the Caucasus
Wheat is the most important cereal in Central Asia (Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan) and the Caucasus (Armenia, Azerbaijan and Georgia). Stripe rust, caused by Puccinia striiformis f. sp. ...
Managing Soil Salinity in the Lower Reaches of the Amudarya Delta: How to Break the Vicious Circle
This case study focuses on the vicious circle of soil
salinization: agriculture’s consumption of large
amounts of water contributes to shallow groundwater,
leading to recurring soil salinity, which in
turn demands more ...
