To evaluate the beneficial Effect of zinc and iron under the influence of drought on Prolin, Protein and Nitrogen Leaf of rapeseed (Brassica napus) . This experiment was conducted in Varamin zone at Iran during 2011-2012. In this respect, the experimental unit had designed by achieved treatments in split plot on the basis completely randomized block design with three replications. Certain factors including three levels of irrigation (I1: normal (control) I2: Irrigation at stem elongation I3: Irrigation at flowering stage) and zinc and iron foliar application (S1: control, S2: zinc spraying, S3: spraying iron S4: iron and zinc spraying) were studied. The results showed that the treatment effects are not significant, but the most effective treatment for dry, drought has bloom. The foliar application of zinc and iron, said to be sprayed simultaneously improve both protein and nitrogen content was noteworthy.
