Abstract:  In order to evaluate the effect of drought stress and salicylic acid on mineral content and some  physiological traits of soybean genotypes (Glycine max L.) a greenhouse experiment was conducted as factorial based on completely randomized design with three replications in Mohaghegh Ardabil University in 2014. The first factor consisted of three levels of water deficit (85%, 65% ...

In order to study the effect of bacterial growth on water use efficiency of alfalfa, a greenhouse experiment, as factorial based on completely randomized blocks design with three replications, was conducted at Faculty of Agriculture, University of Mohaghegh Ardabili, Ardabil, Iran, in 2012.

Nitrogen has an important role for supplying carbon skeletons which needs for producing compatible solutes and stress tolerance enzymes. Water deficit affects nitrogen fixation in legums. So we studied the effect of various nitrogen sources on physiological, and biochemical features of bean under water stress. This experiment was conducted as factorial based on completely randomized design with...
