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 ...
Management practices for improving water productivity in the Dasht-e-Azadegan
Wheat is the main cultivated crop in the LKRB (mainly the Dashte- Azadegan plain). Its average yield is 1500 kg/ha (Agricultural Statistics 2004). Irrigation management practices are traditional and the region suffers from ...

This presentation highlights:
1) Constraints to winter crop production under climate change.
2) Germplasm introduction.
3) Progress on yellow rust resistant wheat varieties.
4) Progress on salinity tolerant wheat.

Hypericin from Hypericum triquetrifolium in wild and under cultivation: variation revealed by genetic distance
Hypericin content and genetic diversity were studied in 27 wild populations of Hypericum triquetnfolium in Jordan. The wild populations were explored from arid to semi-humid areas (176 to 582 mm), growing in varied altitude ...
Graphic Analysis of Trait Relations and Genotype Evaluation in Durum Wheat
Trait profiles of genotypes and trait relations are frequently influenced by unpredictable conditions in the Mediterranean rainfed regions. Thus, genotype selection should be based on multiple traits in variable environments ...
Monitoring Soil Moisture under Wheat Growth through a Wireless Sensor Network in Dry Conditions
Drought research requires data on precipitation and actual soil moisture of fields because precipitation is variable among years and the soil textures differ with crop fields. Measurement of soil water content in the field ...
Plant Nutrient Management in Rainfed Farming Systems
Global population growth and land-use pressure are placing increasing emphasis on expanding crop and animal output in rainfed agriculture. Rainfed areas of the world have some common features, but some unique biophysical ...
Tracking of powdery mildew and leaf rust resistance genes in Triticum boeoticum and T. urartu, wild relatives of common wheat
Wild Triticum and Aegilops species are increasingly used in wheat breeding programmes around the world as donors of genes conferring resistance to biotic and abiotic stresses, as well as of genes that contribute to the ...
Improving Rainwater Productivity with Supplemental Irrigation in Upper Karkheh River Basin of Iran
The Karkheh River Basin (KRB) is located in the south-western parts of Iran. Most of the agricultural area in the upper KRB is rainfed and a large part of the region’s agricultural livelihood is based on dryland farming ...
Xanthium strumarium: a weed host of components of begomovirus-betasatellite complexes affecting crops
Xanthium strumarium is a common weed that often shows symptoms typical of begomovirus infection, such as leaf curling and vein thickening. The virus complex isolated from the weed consisted of two begomoviruses along with ...
