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 ...
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 ...
Plant populations for triticale in a mediterranean environment
Plant population experiments with triticale were conducted for three seasons using a range of agronomic treatments at Aleppo, Syria. The optimum population (the population resulting in maximum grain yield) was higher under ...
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 ...
Production of green feed and grain from grazed barley in Northern Syria
The effects on barley production of variety, seed rate, nitrogen fertilizer rate and timing of grazing were studied in experiments grazed by sheep. The production of green material at the tillering stage and subsequent ...
Advancing the climate data driven crop-modeling studies in the dry areas of Northern Syria and Lebanon: An important first step for assessing impact of future climate
Inter-annual and seasonal variability in climatic parameters, most importantly rainfall, have potential to cause climate-induced risk in long-term crop production. Short-term field studies do not capture the full nature ...
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 ...
Effects of fertilizer on root growth and water use of barley in northern Syria
Barley (cv. Beecher) was grown at two sites (Jindiress and Breda) in northern Syria, chosen for their contrasting edaphic and climatic conditions. At both sites, three fertilizer treatments were applied zero (Z), 60 kg ...
Ecogeography of annual legumes in Syria: distribution patterns
(1) Climate and soil factors influencing the distribution of annual legume species collected at 207 sites throughout Syria were investigated by cluster analysis. (2) Different genera were found to show distinct geographic ...
Pathogenecity of Pratylenchus thornei on chickpea in Syria
A field experiment was conducted in Syria in 1988 to relate yield of chickpea to soil population densities of the root-lesion nematode, Pratylenchus thornei. The field, infested with 0 to 32 nematodes/cm³ soil, was divided ...
