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 com pletely
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 (RW C) > 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 estim ate soil potassium supply w ithin dry or semidry
areas as most challengeable issues of environmental safety.
Key words: Potassium, sorghum, corn, grain growth rate, drought stress, ,
