Abstract :

In order to study effect of PGPR and water deficit on agronomical traits of wheat (cv. Shahriar), an experiment was conducted in the research station of Islamic Azad University- Arak Branch, Iran in 2009-2010. The experimental design was split factorial based on RCBD with three replications. The treatments including of water deficit stress in three level: 50%, 75% and 100% crop water requirement in were assigned to main spilt and plant grow promote regulators including of salicylic acid(without and with using) and CCC(Chlormequat chloride) (without and with using) as factorial were randomized to sub plot. Results showed water deficit stress reduced traits. Bat with sprayed CCC and SA in water deficit and irrigation equal 100% crop water requirement increased length ear weight ear per in ear weight and yield treats. In condition of irrigation equal 75% and 50% crop water requirement, application of along salicylic acid and CCC  as compared without use these, increased yield and yield component. Using of together salicylic acid and CCC increased yield grain by 13.5% as compared with control.  In general results this experiment showed that under water limitation condition, with irrigation equal 75% crop water requirements and use together salicylic acid and CCC can obtain to yield of acceptable.
