Relationship of seedling and adult plant resistance and evaluation of wheat germplasm against tan spot (Pyrenophora tritici-repentis)
Genetic resistance is the most effective, economical and environment friendly method of managing tan spot of wheat caused by the ascomycete Pyrenophora tritici-repentis (Died.) Drechs. (anamorph Drechslera tritici-repentis, Died.). This study...
Ecological dynamics of protected and unprotected rangelands in three climatic zones of Syria
Although rangelands cover approximately 10.5 million ha in Syria, no comprehensive description of rangelands or benchmark sites is available. This study describes some important characteristics on both ecologically healthy and unhealthy sites in...
Epidemiology of nematode parasites of sheep around Jimma, southwestern Ethiopia
An investigation was made into the epidemiology of nematode infections of sheep in two districts of Jimma zone, southwestern Ethiopia. We used two approaches—long-term monitoring of identified sheep for nematode infection and abattoir or market...
Effects of partial replacement of concentrate with feed blocks on nutrient utilization, microbial N flow, and milk yield and composition in goats
Two experiments were carried out to evaluate the effect of partial replacement of concentrate with 2 types of feed blocks (FB) on rumen protozoa numbers, nutrient utilization, microbial N flow to the duodenum, and milk yield and composition in...
Managing water in rainfed agriculture - The need for a paradigm shift
Rainfed agriculture plays and will continue to play a dominant role in providing food and livelihoods for an increasing world population. We describe the world's semi-arid and dry sub-humid savannah and steppe regions as global hotspots, in...
Improving agricultural water productivity: Between optimism and caution
In its broadest sense, water productivity (WP) is the net return for a unit of water used. Improvement of water productivity aims at producing more food, income, better livelihoods and ecosystem services with less water. There is considerable...
Pathotype and microsatellite analyses reveal newsources of resistance to barley scald inTunisia
We examined the variation and relationships between pathogenicity and a microsatellite-based haplotype in 79 Tunisian Rhynchosporium secalis isolates that were collected from the most commonly cultivated barley populations in Tunisia, Rihane cv...
The Challenges of Wastewater Irrigation in Developing Countries
The volume of wastewater generated by domestic, industrial and commercial sources has increased with population, urbanization, improved living conditions, and economic development. The productive use of wastewater has also increased, as millions...
Variation of Soil Physical Properties and Moisture Content Along Toposequences in the Arid to Semiarid Area
Accurate prediction and characterization of the spatial distribution and temporal variation of soil water is indispensable to optimize the use and management of land within dry areas, which suffer from limited arable land and water resources...
Genetic variability of some agronomic traits in the Iranian Fenugreek landraces under drought stress and non-stress conditions
This study was carried out to assess the genetic diversity and heritability of various agronomic traits using twenty fenugreek landraces from Iran. The trial was conducted at Maragheh experiment station in North-west of Iran under rainfed (RF)...
