Abstract

To investigate effects of potassium application and irrigation regimes on the quantitative and qualitative yields of Forage Sorghum (Speed-feed cultivar) in dry regions, an experiment was conducted using a factorial design with three replications and three irrigation regimes (irrigation after depletion of 40, 60 and 80 percent of field capacity) and four potassium rates (0, 50, 100 and 150Kg ha-1) in Sistan region, southern Iran. Stomatal resistance, water use efficiency, yields and plant height were measured in all treatments throughout growth season. The results showed, water stress had very significant effects on plant height, wet forage yield, dry forage yield, leaf stomata resistance and water use efficiency. Potassium fertilizer application on the dry and wet foliage yield, leaf stomata resistance and water use efficiency were high significant.
