| Abstract | ||
| In order to study the effect of irrigation frequency and water quality on yield and yield components of wheat, a study was conducted in Rodasht Agricultural Research Station, for 3 years. The experiment was laid in a randomized complete block design with three replications. Irrigation water quality treatments had electrical conductivities (EC) of 4, 8, and12 dSm-1 and were assigned to the main plot. Treatments of irrigation frequency were based on the percentage of management allowable depletion (30%, 50%, and 70%) and were allocated to the sub-plots. Statistical analysis results showed that the effect of irrigation water quality and irrigation frequency on the yield, water use, water use efficiency, weight of 1000 grains, and protein content was significant at the one percent level. The highest yield was produced by 30% management allowable depletion and 4 dSm-1irrigation water EC and reached 14593 kg.ha-1, while the lowest yield belonged to 70% management allowable depletion and 12 dSm-1 irrigation water EC yielding only 7347 kg.ha-1. The highest percentage of protein was related to the same treatment. The highest water use efficiency of 0.99 kg.m-3 belonged to 70% management allowable depletion and 4 dSm-1 irrigation water EC. | ||
