Abstract

In this experiment, interactive effects of different potassium application and water restrict on grain growth in Iran. The experimental unit had designed by achieved treatment in factorial on the basis completely randomized block design with three replicates. Certain factors including potassium and non-potassium applications (0 and 200 kg/ha), certain field crops (corn and sorghum) and water supply were studied. In this study crops water supply was determined by indicated irrigation conditions by keeping leaf Relative Water Content (RWC)>95% (non-drought stress condition or irrigation conditions) and drought condition by RWC=60-70%. We noticed, however K fertilizer significantly increased the grain growth rate of plants and although the non-drought stress treatment significantly increased grain growth rate. Whereas K application persist less damaging of drought stress result and it enabled plant to significantly grow its grain under the drought conditions. Our finding may give applicable advice to commercial farmers and agricultural researches for management and concern on fertilizer strategy and carefully estimate soil potassium supply within dry or semidry areas as most challengeable issues of environmental safety.
