Evaluation of a cassava germplasm collection for reaction to three major diseases and the effect on yield
Thirty-five cassava (Manihot esculenta Crantz) genotypes from the International Institute of Tropical Agriculture (IITA), germplasm collection were planted in May 1992 under natural disease infection conditions, at the ...
Agrometeorological aspects of agriculture and forestry in the arid zones
The arid zones of the world are all characterized by a large deficit of rainfall in relation to the potential evapotranspiration. Their distribution around the world is governed by the interaction of global atmospheric ...
Comparison of conservation tillage systems in barley-based cropping systems in Northern Syria
Yields of rainfed barley (Hordeum vulgare) for feed and forage in small-ruminant production systems in low-rainfall areas of North Africa and West Asia are limited by low and erratic water availability. Therefore, the ...
A model-farm approach to research on crop-livestock integration — II. Experimental results
A six-year project was conducted to show how better crop-livestock integration and improved management increase the outputs of crops and sheep products. Three farm types were compared, consisting of different crop and sheep ...
Long-term yield patterns in barley-based cropping systems in Northern Syria. 2. The role of feed legumes
Rotations of barley with feed legumes produce more biomass and crude protein than barley-fallow and continuous barley sequences, but scope remains to improve the potential value to farmers of feed legume-based systems. ...
Registration of 'Orca' barley
Registration of 'Orca' barley.
A model-farm approach to research on crop-livestock integration — III. Benefits of crop-livestock integration and a critique of the approach
A six year on-station research project used a model-farm approach to study the benefits of improved crop-livestock integration, achieved through the introduction of leguminous forage species into crop rotations. Previous ...
Tah village project in Syria: Another unsuccessful attempt to introduce ley-farming in the Mediterranean basin
A participatory on-farm research project was started at Tah village, 100 km south of Aleppo, Syria in 1984. The objective was to introduce annual medics (Medicago spp.) as a replacement for fallow in dryland wheat (Triticum ...
Effects of gastro-intestinal and lungworm nematode infections on ewe productivity in farm flocks under variable rainfall conditions in Syria
Ten farm flocks in north-west Syria were monitored over four years to determine the effect of gastro-intestinal and lungworm nematode infections on Awassi ewe productivity. A group of ewes in each flock served as the ...
Sources of resistance to downy mildew in narbon (Vicia narbonensis) and common (Vicia sativa) vetches
Downy mildew (Peronospora viciae (Berk) de Bary) is an important disease of vetches (Vicia spp.) in the Mediterranean Region. Narbon and common vetch germplasm accessions originating from different countries, and advanced ...
