Monitoring Restoration Impacts to Endemic Plant Communities in Soil Inclusions of Arid Environments
Slickspots are soil inclusions with unique loamy soils that provide habitats for many endemic plants worldwide, including those within sagebrush steppe. Sagebrush-dominated communities are declining and require restoration, but restoration...
Rivers and flooded areas identified by medium-resolution remote sensing improve risk prediction of the highly pathogenic avian influenza H5N1 in Thailand
Thailand experienced several epidemic waves of the highly pathogenic avian influenza (HPAI) H5N1 between 2004 and 2005. This study investigated the role of water in the landscape, which has not been previously assessed because of a lack of high...
Hill lakes : innovative approach for sustainable rural management in the semi-arid areas in Tunisia
In Tunisian semi-arid regions, where water is a rare commodity and the large dams cannot be justified considering the very limited water contributions and the very high evapotranspiration, innovative techniques of harvesting water have been...
The Impacts of an Improved Technology Package on Production Efficiency: The Case of Wheat Farms in the Northern State of Sudan
Technical efficiency among wheat farms in the Northern State of Sudan was estimated using a stochastic frontier production function approach. Empirical findings show that technical inefficiency is important in explaining the variations in yield...
Reliability of Yield Mapping System for Estimating Perennial Ryegrass Seed Yield
Seed yield is an important factor to any farmer. Most farmers recognize that yield will vary within a field due to many factors, but they are unaware of the actual magnitude of the yield variability. Yield mapping is a technique whereby the...
Wheat (Triticum aestivum L.) flour represents one of the primary sources of calories and proteins for the human diet. The increase in the wheat yield without losing its baking and milling quality is an important breeding objective. The use of...
NARROWING YIELD GAPS THROUGH GENETIC IMPROVEMENT FOR FUSARIUM WILT RESISTANCE IN THREE PULSE CROPS OF THE SEMI-ARID TROPICS
Chickpea, pigeonpea and lentil constitute the major component of low-input agriculture in the semi-arid tropics (SAT). These pulses play an important role in alleviating malnutrition by way of forming an inseparable component to the dietary...
Ties that Bind: ICARDA in Central Asia and the Caucasus: A Partnership Dedicated to Sustainable Agriculture Development and Food Security
The Central Asia and the Caucasus (CAC) region is a vast area of desert, steppe and mountain. For centuries its people have battled against a difficult climate, characterized by low and unpredictable rain fall and extremes of temperature. During...
Measuring and modeling the effects of drainage water management on soil greenhouse gas fluxes from corn and soybean fields
Controlled tile drainage can boost crop yields and improve water quality, but it also has the potential to increase GHG emissions. This study compared in-situ chamber-based measures of soil CH4, N2O, and CO2 fluxes for silt loam soil under corn...
Characterization and Assessment of Genetic Diversity of Wild Date Palm (Phoenix dactylifera) in Jordan
This thesis has been submitted by Mu’wya Ayed Alasasfa in partial fulfillment of the PhD Degree in Horticulture and Crop Science, University of Jordan, under the co-supervision of Dr. Mahmud A. Duwayri (University of Jordan) and Dr. Ayed...
