Genetic structure, diversity, and allelic richness in composite collection and reference set in chickpea (Cicer arietinum L.)
Background: Plant genetic resources (PGR) are the basic raw materials for future genetic progress and an insurance against unforeseen threats to agricultural production. An extensive characterization of PGR provides an ...
Barley and Vetch yields from dryland rotations with varying tillage and residue management under Mediterranean conditions
With increasing land-use pressure in semi-arid, dryland Middle Eastern agriculture, fallow-based cereal production has given way to cropping intensification, including legume-based rotations along with conservation tillage ...
Nitrogen mineralization potentials of selected mediterranean soils
To gain a better understanding of N availability in Mediterranean soils, 18 surface (0–20cm) soil samples were selected from soil groups of Syria for study of their N mineralization potentials. The chosen soils represented ...
Effect of Tillage System on the Spontaneous Regeneration of Two Annual Medics (Medicago Spp.) After Wheat in North Syria
Four tillage treatments were applied to soil on which wheat was to be sown in 1988/89 after pastures of two annual medics, Medicago rigidula and M. polymorpha, had been established in 1987/88. Germination of the medics was ...
Rapid global spread of two aggressive strains of a wheat rust fungus
Rust fungi can overcome the effect of host resistance genes rapidly, and spores can disperse
long distance by wind. Here we demonstrate a foreign incursion of similar strains of the
wheat yellow rust fungus, Puccinia ...
On-Farm Assessment of Improved Crop Production Practices in Northwest Syria. I. Chickpea
Thirty on-farm trials were conducted in northwest Syria over a period of four seasons to examine the main effects and interaction of sowing date, sowing method, Rhizobium inoculation, phosphate application and weed control ...
Changing Barley Fertilization Policy in Syria: The Role of Collaborative Policy-oriented Research
Barley is a major feed crop in Syria, accounting for 96 percent of the area devoted to rainfed forage crops, 40 percent of the total cereal area, and 27 percent of the total cropped area. Although barley is well adapted ...
Soil test standardization in west Asia‐North Africa Region
In dryland fanning of the Mediterranean zone, which has rain in the winter with long dry summers, inadequate soil moisture is generally the dominant factor limiting crop growth. Nitrogen (N) and phosphorus (P) can significantly ...
Assessment of soil and plant analysis laboratories in the West Asia‐North Africa Region
Although limited amount of water is the primary constraint to agricultural productivity in the rainfed area of West Asia and North Africa (WANA), yields are also low because of the poor mineral nutrient status of soils. ...
The role of informal farmer-to-farmer distribution in diffusion of new barley varieties in Syria
This study examines the role, structure and effectiveness of informal seed systems in the diffusion of new barley varieties. It uses data collected by tracing farmers who received new barley varieties and other farmers who ...
