Common bean (Phaseolus vulgaris L.) is the most important food legume in the diet of poor people in the tropics. Drought causes severe yield loss in this crop. Identification of traits associated with drought resistance contributes to improving the process of generating bean genotypes adapted to these conditions. Field studies were conducted at the International Center for Tropical Agriculture ...

Drought is one of the major natural hazards that bring about billions of dollars in loss to the farming community around theworld each year. Drought is most often caused by a departure of precipitation from the normal amount, and agriculture is often the first sector to be affected by the onset of drought due to its dependence on water resources and soil moisture reserves during various stages ...

Droughts are related with prolonged periods when moisture is significantly below normal values. Drought indices attempt to scale the main drought features to facilitate comparisons. Numerous indices are found in the literature based on different drought features. Many of them were created for particular places and specific objectives, and therefore not suitable to generalize the results. Howeve...

Drought is the dominant process of crop loss nationally and within Nebraska. Nearly twothirds of the 18.6 million harvested acres are covered by crop insurance (USDA/RMA, 2003; USDA/NASS, 2003). For the most part, Nebraska’s crop losses range from $50 to 75 million in non-drought years, but the losses approach nearly $200 million in drought years, such as 2000. The past growing season (2002) cr...

A field experiment with two sets, each comprising 13 chickpea genotypes with three replications was carried out during Rabi 2012-2013 in stress and non-stress conditions. The objective of the reported research was to study the response of chickpea genotypes in drought stress and to screen the appropriate genotypes performing better in water deficit and irrigated conditions. Three genotypes TG12...

The National Agricultural Decision Support System (NADSS) is a web based geospatial decision support system used to aid producers and decision makers in analyzing and effectively mitigating the effects of drought. The NADSS application is unique in its implementation, containing web-based implementations of commonly utilized drought indices including the Newhall Simulation Model (NSM), Palmer D...

drought affects on all aspects of human actirities seriously as a climatic phenomenon. however, the studies related to this phenomenon based on suitable method are very few. studying the drought features and its prediction can be effective on decreasing of resulted losses or damages. therefore, drought and evaluation of its prediction possibility are studied for some stations of ardabil provinc...

aridity and drought are two inevitable occurrences of the climate change in the region. so, any kinds of planning and futurism, without regard to them, lead to failure. climate change cause drought phenomenon. the anomalies and irregularities in the precipitation mainly cause drought. fars province, one of the important centers of agriculture, population and industry in the country, with specif...

in order to evaluate the effects of drought stress at different phenological stages on growth indices of chickpea (cicer arietinum l.) cultivar jam, an experiment was carried out at the research greenhouse of faculty of agriculture, ferdowsi university of mashhad, using a completely randomized design with four replications. drought stress was applied by preventing irrigation until the soil mois...
