There is an emerging interest in on-the-go mapping of apparent soil electrical conductivity (ECa) as a surrogate spatial map for soil properties. The quality (or precision and accuracy) of ECa maps as affected by the swath width of the...

Competition among eight Rhynchosporium secalis isolates was assessed during parasitic and saprophytic phases of the disease cycle in field experiments conducted at two locations and over two growing seasons. The eight isolates were inoculated...

Desertification is nowhere more serious han in the Middle East and North Africa (MENA), stretching from Pakistan in the east to Morocco in the west, and from Ethiopia and Sudan in the south to Turkey in the north. Yet, many MENA countries have...

GAP (Guneydogu Anadolu Projesi or Southeastern Anatolia Project) is a multisector integrated regional development project in Turkey, and one of the largest integrated rural development projects in the world. It is a multibillion dollar project...

This issue of Caravan looks at different aspects of desertification; and how ICARDA and its partners are working together to help farming communities find effective, sustainable solutions. These collaborative efforts have generated significant...

Barley, one of the earliest crops in human history, is grown in over 100 countries. In the West, it is used mainly for animal feed or as malt for producing beverages. In developing countries it is a staple food for millions of people. Developing...

Currently at least 20 per cent of the world's irrigated land is salt-affected. However, projections of global population growth, and of an increased demand for food and fibre, suggest that larger areas of salt-affected soil will need to be...

The year 2005 was an important milestone in the efforts of ICARDA and its partners in meeting the global challenges of agriculture in dry areas through the application of science. In an assessment of all 15 CGIAR Centers (based on science...

n agricultural research conducted in dry areas, crop-yield water use efficiency (WUE) is a measure used to evaluate the impacts of various agronomic factors on crop productivity. Agronomic management factors include supplemental irrigation (SI)...

To understand the mechanisms of aluminum (Al) tolerance in wheat (Triticum aestivum L.), suppression subtractive hybridization (SSH) libraries were constructed from Al-stressed roots of two near-isogenic lines (NILs). A total of 1,065 putative...
