Abstract :
Organic matters are useful sources to improve soil quality and increase the yield in plants. In order to assess the effects of different fertilizers application on yield and yield components of barley (Hordeum vulgare L. Makoii cultivar) under water stress, a field experiment was conducted on Research Farm of Faculty of Agriculture of Tarbiat Modares University at growing season 2014-2015. The experiment was conducted as split plot arranged in a randomized complete blocks design with three replications. The main plots were three water stress (optimal irrigation, withholding irrigation at vegetative growth stage and reproductive growth stage) and six levels of fertilizers (control, manure, municipal waste chopped, vermicompost, azocompost and urea) were in subplots. There was a significant effect of water stress and fertilizers on the plant height, grain yield, biological yield, grains per spike and number of spike per m2. Overall, the plants were more sensitive to water stress at the reproductive stage and vermicompost and azocompost could moderate disadvantages of water stress on plants.
