In 2007, new reports of stem rust caused by Puccinia graminis Pers. f. sp. tritici Eriks. in Lorestan and Hamadan provinces of Iran were considered unusual because stem rust had not been recorded previously in the Hamadan area where winter habit...

The world population is expected to reach about 8 billion by 2025 (United Nations, 2006), before it stabilizes at about 10-11 billion towards the end of the 21st century. Most of this increase in population is expected to occur in less-developed...

Vast areas of the rangelands (badia) of West Asia and North Africa are severely degraded due to over-grazing, cutting of shrubs and ploughing. Because of the scarce vegetation cover and the often dense soil surface crust, a large part of the...

This issue of Caravan describes some of ICARDA's work on climate change. It contains overviews of the key issues, and articles describing research in specific areas. We examine, for example, how genetic resources – landrace varieties, wild...

Collaboration between ICARDA and Jordan began when ICARDA was established in 1977. A bilateral agreement was signed on 27 October that year. The first Memorandum of Understanding (MoU) was signed with the Ministry of Agriculture, identifying...

Background Drought is the major constraint to increase yield in chickpea (Cicer arietinum). Improving drought tolerance is therefore of outmost importance for breeding. However, the complexity of the trait allowed only marginal progress. A...

Forty factorial experiments with 4 levels of N (0, 40, 80, and 120 kg N/ha and 4 levels of P (0, 8.8, 17.5, and 35 kg P/ha) with two replicates were conducted in farmers’ fields during two consecutive seasons in 1987 and 1988. The sites chosen...

In 2007, ICARDA celebrated its thirtieth anniversary. The Center and its partners have worked together for three decades to improve the food security and livelihoods of the poor in dry and marginal areas. During this time, we have seen...

Field surveys were conducted in northern Ethiopia during the 2004 and 2005 cropping seasons to determine the distribution of chocolate spot (Botrytis fabae) and the association of disease parameters (incidence and severity) with crop management...

Background: Plant genetic resources (PGR) are the basic raw materials for future genetic progress and an insurance against unforeseen threats to agricultural production. An extensive characterization of PGR provides an opportunity to dissect...
