The Jabali mountain goats inhabit the extremly unfriendly and harsh environment of western Syria, where they are kept by different ethnic groups, namely, the Alawits, Druses and Bedouins. The Jabali goat is a black goat, with dropping cars and a...
Mapping adaptation of barley to droughted environments
Identifying barley genomic regions influencing the response of yield and its components to water deficits will aid in our understanding of the genetics of drought tolerance and the development of more drought tolerant cultivars. We assembled a...
Survey of faba bean and field pea viruses in Yunnan Province, China
In a survey of faba bean ( Vicia faba) and field pea ( Pisum sativum)fields in China's Yunnan Province during March 2004, more than 5000 plant samples were collected from 35 locations and tested by tissue-blot immunoassay for the presence of up...
Changement réel et changement induit Décalage ou perpétuelle recherche pour les zones arides d'Afrique du Nord
L'histoire des politiques de développement économique et social au Maghreb a fortement marqué l'évolution des systèmes agropastoraux des zones arides. En l'espace de 50 ans, on est passé de systèmes d'élevage pastoraux à des systèmes mixtes...
Promoting the adoption of natural resource management technology in arid and semi-arid areas: Modelling the impact of spineless cactus in alley cropping in Central Tunisia
The arid and semi-arid areas of North Africa arc becoming deserts. Most of the research and development projects in these areas aim at developing alternative technologies to reduce land degradation and favour sustainable economic activities. The...
Approaches to rationalising selection of test environments for on-farm lentil variety trials in Mediterranean rainfed cropping systems
This study focused on various approaches to rationalising the selection of test environments using on-farmtrial data from 5 lentil (Lens culiniaris Medikus subsp. culinaris) genotypes. It was conducted over 3 years in 30 environments across 16...
Genetic diversity of Rhynchosporium secalis in Tunisia as revealed by pathotype, AFLP, and microsatellite analyses
Genetic variability among 122 Rhynchosporium secalis isolates collected from barley in three regions of Tunisia was investigated using host differentials, amplified fragment length polymorphism (AFLP), and microsatellite markers. The isolates...
Amelioration and nutrient management strategies for sodic and alkali soils
Sodic and alkali soils are characterized by the occurrence of excess sodium (Na+) to levels that can adversely affect soil structure and disturb the availability of nutrients for plant growth. Structural problems in these soils are created by...
Agricultural use of marginal - quality water - opportunities and challenges
This section examines the main types of marginal-quality water: wastewater from urban and peri-urban areas and saline or sodic agricultural drainage water and groundwater
