modeling of crop growth plays an important role in evaluation of drought impacts on rainfed yield, choosing an optimum sowing date, and managerial decision-makings. aquacrop model is a new crop model that developed by food and agriculture organization (fao), that is a model for simulation of crop yield based on “yield response to water“ with meteorological, crop, soli and management practices d...

an experiment was carried out in 2008 to investigate the effects of different irrigation regimes, and chickpea cultivars on chickpea production in the khorramabad lorestan. the experiment was split–plot in a randomized complete block design with 3 replications. supplementary irrigation at 8 levels (1-rainfed without irrigation, 2-irrigation after sowing, 3-irrigation at flowering, 4-irrigation ...

­­Drought is one of the most destructive abiotic stresses worldwide that affects growth, development and final yield of crops. Reactions of thirteen rainfed spring 2-row barley genotypes and cultivars of cold areas of Iran to water stress were evaluated based on phenological, physiological and morphological traits. The experiment was carried out as factorial experiment based on a randomized com...

to identify and characterize bread wheat (triticum aestivum l.) genotypes adapted to terminal water deficit conditions, 51 superior hexaploid wheat genotypes together with commercial check cultivars were studied, in a two stages screening practice, for drought tolerance in karaj, kermanshah, isfahan, neishabour and varamin filed stations under terminal water deficit conditions in 2002-2005 grow...

The role of urban agriculture in global food security is a topic of increasing discussion. Existing research on urban and peri-urban agriculture consists largely of case studies that frequently use disparate definitions of urban and peri-urban agriculture depending on the local context and study objectives. This lack of consistency makes quantification of the extent of this practice at the glob...

Golestan province is one of the major regions of wheat production in the country. Azospirillum brasilense، an Azotobacter، acted as resolvent of phosphate and a microorganisms for fixing molecular nitrogen for cooperating with other root crops and grasses in enhancing their growth and development. To investigate the effects of rhizobacteria on yield and yield components of wheat a  factorial ex...
