Relationships of grain delta C-13 and delta O-18 with wheat phenology and yield under water-limited conditions
Stable carbon isotope composition (delta C-13) of dry matter has been widely investigated as a selection tool in cereal breeding programmes. However, reports on the possibilities of using stable oxygen isotope composition ...
Assessment of on-farm conservation of dryland agrobiodiversity and its impact on rural livelihoods in the Fertile Crescent
The Fertile Crescent encompasses a mega-center of diversity of crops and livestock of global importance. The
International Center for Agricultural Research in the Dry Areas (ICARDA) coordinated a 5-year regional project
funded ...
Yield gain due to fungicide application in varieties of winter wheat (Triticum aestivum) resistant and susceptible to leaf rust
In three independent experiments in Turkey and Kazakhstan, winter wheat germplasm with variable degrees of resistance to leaf rust was subjected to fungicide protection. The yield loss of genotypes susceptible to leaf rust ...
Soil organic matter and related physical properties in a Mediterranean wheat-based rotation trial
Under semi-arid Mediterranean conditions, limited moisture is the main constraint to rainfed cropping with wheat (Triticum aestivum), barley (Hordeum vulgare), and food and forage legumes. With increasing land-use pressure, ...
Association Mapping of Resistance to Yellow Rust in Winter Wheat Cultivars and Elite Genotypes
Yellow (stripe) rust, caused by Puccinia striiformis
f.sp. tritici (Pst), is a destructive disease of
wheat (Triticum aestivum L.) all over the world,
particularly in the Central and West Asia and
North Africa (CWANA) ...

تهدف الدراسة إلى اظهار الآثار والمعوقات الاقتصادية و الاجتماعية والبيئية لحشرة السونة على إنتاج القمح في سورية والعمل على تقليلها من خلال تطوير وتطبيق خيارات الإدارة المناسبة للمكافحة المتكاملة لحشرة السونة بتكاليف منخفضة ...
Changes in the size and composition of the seed bank of medic pastures grown in rotation with wheat in north Syria
A mixture of 84 accessions of 12 medic (Medicago) species were sown in two successive years into a two-course pasture/wheat rotation in north Syria. Changes in the size and botanical composition of the seed bank were ...
Predicting the number of nymphal instars plus new-generation adults of the Sunn Pest from overwintered adult densities and parasitism rates
The present study evaluated the effect of overwintered adult density and egg and adult parasitism rates on the new-generation population densities of the Sunn Pest (Eurygaster integriceps Put.) under field conditions. We ...
Harvest index is a critical factor influencing the grain yield of diverse wheat species under rain-fed conditions in the Mediterranean zone of southeastern Turkey and northern Syria
Environmental and plant factors critical to the grain yields of bread (Triticum aestivum L.), durum (T. durum L.) and emmer (T. dicoccum L.) wheat cultivars were investigated at two Mediterranean rain-fed eld sites: Adana ...
Where in the value chain are we losing the most food? The case of wheat in Jordan
Efforts to increase global food supply through increased productivity and intensity of cropping are well documented. However, the literature on measurement of food losses and wastage and techniques to reduce them is scanty. ...
