This study was carried out during three successive seasons 2004/05, 2005/06 and 2006/07, to evaluate fifty F derived lines (from the F diallel cross), with three check varieties under two different irrigation regimes. 3 2 Twenty different lines were selected from the fifty F lines under each level of irrigation and evaluated under 3 the same conditions in the F and F generations. Also, the effe...

to evaluate the quantitative and qualitative of forage in intercropping of sorghum and chickling pea under limited irrigation systems, an experiment was conducted in research farm, college of agriculture, university of tehran, during 2009 and 2010. the treatments were arranged as split plots consisted of three levels of irrigation regimes including control (irrigation after 70mm evaporation fro...

Crop show morphological and physiological responses to microbial, physical or chemical factors which are known as elicitors. Chitosan is a natural biopolymer modified from chitin, which is the main structural component of squid pens, cell walls of some fungi and crab shells. Water stress is one of the most important abiotic stresses that affects plant physiological and morphological traits. In ...

Raw produce is increasingly recognized as a vehicle of human gastroenteritis. Non-typhoidal Salmonella, pathogenic Escherichia coli, and other human pathogens have been isolated from fruits and vegetables in the field and in the marketplace, which led to the hypothesis that these microbes can use plants as alternate hosts. However, environmental and physiological factors that facilitate persist...

There is increasing evidence of the contribution of irrigation water in the contamination of produce leading to subsequent outbreaks of foodborne illness. This is a particular risk in the production of leafy vegetables that will be eaten raw without cooking. Retailers selling leafy vegetables are increasingly targeting zero-risk production systems and the associated requirements for irrigation ...

The impact of climate change on the ecosystem of the Mediterranean Sea basin will be manifested mainly by a significant reduction in water resources, because of rising temperatures and lower rainfall despite the increase in heavy precipitation events. Water is a fundamental resource for the metabolic activities of plants in agriculture. Unfortunately this resource is available in limited quanti...
