Abstract
A field experiment was laid out in order to evaluation of effects water stress on yield and yield components of wheat cultivars in Lorestan province in Islamic Azad University, Boroujerd branch, Iran at 2014. The experiment was laid out in a split-plot design based on randomized block design with three replications. Treatments were irrigation in five levels such as 1: four period irrigation after anthesis, 2: three period irrigation after anthesis, 3: two period irrigation after anthesis, 4: one period irrigation after anthesis and 5: control in main plots and three wheat cultivars (Shiraz, Pishtaz and Bahar) in sub plots. The results showed that, the effect of water stress, cultivar and interaction between them on all parameters were significant at 1% level. The height of Pishtaz cultivar was taller than other cultivars. The Pishtaz cultivar with one period irrigation after anthesis had the highest number of spike per square and Bahar cultivar with one period irrigation after anthesis had the lowest number of spike per square. However, 1000- grainwas decreased in water deficit treatment. However, the Pishtaz cultivar with four period irrigation had the highest plant dry weight and grain yield and Bahar cultivar non irrigation treatment after anthesis had the lowest plant dry weight and Shiraz cultivar in non-irrigation treatment had the lowest grain yield. The results showed that yield and yield components of common wheat decreased with increasing of water deficit and for increasing in grain yield of wheat complete irrigation are needed. However, Pishtaz cultivar had a highest grain yield and dry matter production. Then we can increase grain yield and production of wheat with cultivation of Pishtaz cultivar and avoid of water stress.DOI: http://dx.doi.org/10.3126/ijls.v9i5.12707
