AB - The effects of drought stress at different growth stages and nutrition systems were studied on yield and yield components of wheat (Chamran cv.). This experiment was carried out as split plot based on completely randomized blocks design with three replications at Research Farm of Ramin University of Agriculture and Natural Resources, Khuzestan province, Iran, during 2009-2010. Irrigation at three levels of I1 (irrigation cut-back from spike formation stage to harvesting, 55 zadox), I2 (irrigation cut-back in anthesis stage to harvesting, 65 zadox) and I3 (full irrigation, control) were in main plots, and fertilizer systems including chemical fertilizer (NPK), manure (M), biological fertilizer (B) and manure + biological fertilizer (MB) were in sub-plots. Results showed that drought stress and nutrition systems had significant effect on grain yield and biological yield (P LA eng UL http://jcpp.iut.ac.ir/article-1-1678-en.html M3 ER -
