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 ...
Yields of crop dry matter and nitrogen in long-term barley rotation trials at two sites in northern Syria
Trials were established at two sites in 1982 to compare six 2-course rotations, in which barley alternated with feed legumes (pure or mixed with barley), fallow or barley, in partial factorial combination with different N ...
Comparison of categories of resistance in wheat and barley genotypes against biotype 2 of the Russian wheat aphid, Diuraphis noxia (Kurdjumov)
The Russian wheat aphid Diuraphis noxia (Kurdjumov) (Homoptera: Aphididae) is a global pest of wheat and barley. This arthropod is difficult to manage with pesticides or biological control agents due to the aphid’s ability ...
Isolation and sequence analysis of DREB2A homologues in three cereal and two legume species
The transcription factor, DREB2A, is one of the promising candidate genes involved in dehydration tolerance in crop plants. In order to isolate DREB2A homologues across cereals (rice, barley and sorghum) and legumes (common ...
Intercropping wheat and barley with N-fixing legume species: a method for improving ground cover, N-use efficiency and productivity in low input systems
Two cereal cropping systems are described which, through the introduction of a leguminous intercrop, increased productivity, nitrogen output and ground cover of the systems in the absence of added nitrogen fertilizer. ...
Nutrient Dynamics in a Long‐Term Cereal‐Based Rotation Trial in a Mediterranean Environment: Nitrogen Forms
Mediterranean agriculture is mainly rainfed, with drought being the main crop production constraint, and is based on cereals, wheat (Triticum spp), and barley (Hordeum vulgare). Fallow was a traditional practice to conserve ...
Grinding energy and in vitro gas technique for the assessment of Syrian barley straws: physical and microbial degradation and voluntary feed intake by sheep
The extent and rate of in vitro gas production of 40 Syrian barley straws, from various varieties with known dry matter intakes (DMI), were examined. The physical resistance of those straws to particle size reduction was ...
Yield response of barley to rainfall and temperature in Mediterranean environments
Grain yield of barley (Hordeum vulgare L.) in northern Syria is limited by water stress and extremes of temperature. The present study compared the grain yield of two barley cultivars, Harmal (spring type, cold-sensitive, ...
Patterns of genetic diversity and linkage disequilibrium in a highly structured Hordeum vulgare association-mapping population for the Mediterranean basin
Population structure and genome-wide linkage disequilibrium (LD) were investigated in 192 Hordeum vulgare accessions providing a comprehensive coverage of past and present barley breeding in the Mediterranean basin, using ...
Identification and mapping of the leaf stripe resistance gene Rdg1a in Hordeum spontaneum
Leaf stripe of barley, caused by Pyrenophora graminea, is an important seed-borne disease in organically grown as well as in conventionally grown Nordic and Mediterranean barley districts. Two barley segregating populations ...
