Abstract

Preanthesis stored dry matter in wheat (Triticum aestivum L.) is important under a Mediterranean climate because GRAIN FILLING greatly depends on remobilization of preanthesis assimilates. The experiment was carried out at Marvdasht region during 2010-2011 using Complete Randomized Block, Split-split Plot Design with three replications. Main plots consisted of Irrigation treatments which, were I1 (Nonstressed) and I2 (Post ANTHESIS water stressed plots with 50% FC). Sub plots consisted of fertilizer treatments, which were nitrogen at rates of 50 (Low N) and 200 (High N) kg ha-1. Subsub plots, wheat and barley cultivars, were Shiraz, Marvdasht, and Nosrat and Rihaneh. Results showed that application of 200 kg N ha-1 had positive effect on all traits and produced more grain yield. Between wheat and barley Marvdasht cultivar produced the highest grain yield. Drought stress increase DRY MATTER REMOBILIZATION and its efficiency. DRY MATTER REMOBILIZATION and its efficiency were higher in wheat cultivars than barley cultivars. Increasig nitrogen application increased DRY MATTER REMOBILIZATION and decreased its efficiency. Interaction effects of nitrogen and irrigation was significant in most traits. In general, it seems that in order to obtain high grain yield nitrogen should be adjusted with amount of irrigation water.
