A field experiment was conducted to evaluate the crop water stress index (CWSI), grain yield and canopy temperature of triticale under two irrigation regimes at Research Station of College of Agriculture and Natural Resources of Darab, Shiraz University, in 2013. A split plot design was used with three triticale cultivars (Sanabad, ET-83-3, and ET-84-5), as sub-plots and four levels of irrigati...

Large portions of the Great Plains and the western U.S. are regularly plagued by drought and diminishing water resources for irrigation. Alfalfa cultivars adapted to these regions, and that can remain productive under reduced irrigation allotments, are clearly needed. This study evaluated the potential of using DNA marker assisted selection (MAS) technology to improve alfalfa forage productivit...

thrips tabaci is one of the most important pests causing serioues damages on onion s in iran despite several chemical sprayings. to assess the population density and damage of the thips on onion, improved sefid-e-khomein genotype along with seven other iranian cultivars of onoin were planted in a rcb design with four replications in two separate experiments (sprayed and non-spray ed ) in arak f...

in order to evaluate of drought tolerance in different canola varieties based on stress evaluation indices in terminal growth duration, an experiment was conducted as split-plot design on randomized complete block design with four replications at experimental field of seed and plant improvement institute, karaj in 2005 and 2006. results using stress susceptibility index (ssi) and tolerance inde...

Supplemental irrigation under prolonged drought conditions has a key role in providing water for transpiration of rain-fed fig trees. The effect of different times and amounts of supplemental irrigation at different distances from the tree trunk on quantity and quality of Estahban rain-fed fig production was evaluated during two years. A randomized complete block design with four replications o...

in order to evaluate the effect of different levels of drought stress on some physiological parameters in grapevine, a potted experiment with iranian grapevine cultivars ‘sahani’, ‘bidane-sefid’ and ‘farkhii’ was conducted in summer of 2008. the experiment was performed while employing four drought stress (water potential of soil, ?s= -0.2, -0.6, -1, -1.5 mpa) treatments each in three replicati...
