Our previous work demonstrated that boron (B) supplied to soybeans (Glycine max [L.] Merrill cv ;Williams 82') by a stem infusion technique increased the number of pods on branches and led to a significant yield increase. Therefore, research was continued to determine whether soil or foliar applications of B could be used to achieve the same results. Field experiments were completed with both s...

Nitrogen fertilizer management has a special priority for safflower economic production. Increasing the efficiency of this element, in addition to increasing economic benefits, also reduces environmental pollution. Therefore, a factorial experiment was conducted in the form of statistical design of complete randomized blocks with three replications at Safiabad Agricultural and Natural Resources...
