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 and on-farm straw...
Linking participatory plant breeding to the seed supply system
There is a strong link between formal plant breeding and seed supply. In developed countries, it was the emergence of systematic plant breeding that generated new named varieties and stimulated organized seed multiplication and marketing by...
Productivity enhancement of salt-affected environments through crop diversification
Recent trends and future demographic projections suggest that the need to produce more food and fibre will necessitate effective utilization of salt-affected land and saline water resources. Currently at least 20 per cent of the world's...
Quantitative trait loci associated with adaptation to Mediterranean dryland conditions in barley
The objective of the present study was to identify quantitative trait loci (QTL) influencing agronomic performance across rain fed Mediterranean environments in a recombinant inbred line (RIL) population derived from the barley cultivars ER/Apm...
Crop coefficient for drip-irrigated cotton in a Mediterranean environment
A 3-year study was conducted in the eastern Mediterranean region of northern Syria to develop crop coefficient, Kc, for drip-irrigated short-season cotton (Gossypium hirsutum L.). Two sets of Kc curves were determined, the generalized Kc...
Evaluation of the CropSyst model for simulating the potential yield of cotton
Cotton produced in Uzbekistan has a low water and fertilizer use efficiency and yield is below its potential. To introduce improved production methods, knowledge is required on how the agro-ecosystem would respond to these alternatives. For this...
Heterosis and mixing effects in barley under drought stress
Yield stability is one of the main breeding objectives in breeding for stress environments, such as the semi-arid areas of Syria. The objectives of this study were to measure the effects of heterogeneity and heterozygosity on yield and yield...
Opportunities to reduce the vulnerability of dryland farmers in Central and West Asia and North Africa to climate change
The world’s drylands will face not only increasing temperatures with climate change but more importantly also disruptions to their hydrological cycles resulting in less and more erratic rainfall that will exacerbate the already critical state of...
Fruit and Oil Characteristics of Three Main Syrian Olive Cultivars Grown under Different Climatic Conditions
The recent expansion in olive (Olea europaea L.) production in Syria to less favorable areas implies the need for comprehensive studies of cultivars on the characteristics of oil produced in these marginal environments. The objective of this...
Groundwater resources in the Jabal Al Hass region, northwest Syria: an assessment of past use and future potential
In many cases, the development of groundwater resources to boost agricultural production in dry areas has led to a continuous decline in groundwater levels; this has called into question the sustainability of such exploitation. In developing...
