Abstract: (5296 Views)

The aim of this experiment was that study the effect of drought stress and different chemical and organic fertilizers systems on wheat flag leaf chlorophyll. This experiment was conducted as split plot based on completely randomized block design (CRBD) with four replications during 2009-2010 at experimental fields of Ramin university. Irrigation treatments were achived in I1(irrigation droped from anthesis stage to harvesting 55 zadox) and I2 (spike formation to harvesting 65 zadox) and I3 (full irrigation, control treatment), and fertilizers treatment included chemical fertilizer (NPK), manure fertilizer (M), biological fertilizer (B), biological fertilizer + manure fertilizer (MB) at the beginning of plantation. maximum and minimum chlorophyll leaf content were related to I3 and I1, respectively. Also, maximum chlorooyll was related to biological fertilizer mixed with manure (MB) and chemical fertilizers (NPK) and minimum was for biological fertilizer(B), respectively. A positive corelation was observed between grain yield and flag leaf chlorophyll at with high significance. Therefoere, flag leaf chlorophyll is a good trait selection performance under drought stress conditions and different fertilizer systems. .
