مقاومة العائل، الممارسات الزراعية والمكافحة الحيوية مكونات أساسية في برامج المكافحة المتكاملة للآفات; Host Plant Resistance, Cultural Practices, and Biological Control: Essential Components in IPM Programs
A number of pathogens persist in plant remains, and reproduce on them sexually, as they may persevere
on infected seeds, and these become sources of disease transmission from one field to another and from one field to ...
Amplified fragment length polymorphism among Rhynchosporium secalis isolates collected from a single barley field in Syria
AFLP markers were used to measure the amount and distribution of genetic variation among Rhynchosporium secalis isolates on a microgeographical scale in Syria. Forty isolates hierarchically sampled from a single barley ...
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 ...
Chickpea Ascochyta Blight: Disease Status and Pathogen Mating Type Distribution in Syria
Chickpea fields were surveyed in nine major chickpeagrowing
provinces of Syria in 2008 and 2009 to determine
the prevalence and severity of Ascochyta blight,
and the distribution of Didymella rabiei mating types
(MATs) in ...
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 ...
Food Legume Nurseries: International Nursery Report 1982/83
The main objective of the program is to provide a mechanism for the multi-location testing of the genetic material of chickpea, faba beans, and lentils originating from national and International programs.
The testing aims ...

News from CGIAR Collaborative Research Program for Sustainable Agricultural Development in Central Asia and the Caucasus (CAC) covering the countries: Armenia, Azerbaijan, Georgia, Tajikistan, Turkmenistan, Kazakhstan, ...
Incorporating risk in the economic analysis of agronomic trials: fertilizer use on barley in Syria
In the drier areas of Syria yields of barley, the principal crop, are low. Due to the variability in rainfall, fertilizer use is perceived as risky. Barley-fertilizer trials have been conducted on farmer's fields over a ...
Prediction of Soil Depth from Digital Terrain Data by Integrating Statistical and Visual Approaches
Information about the spatial distribution of soil attributes is indispensable for many land resource management applications; however, the ability of soil maps to supply such information for modern modeling tools is ...
