Abstract

High level of salt in irrigation water and soil cause disorder in nutrient uptake, growth and yield reduction in WHEAT. POTASSIUM alone and in combination with calcium sulphate is effective in decreasing the salinity hazard. This study was conducted to determine the effect of SALINE WATER, POTASSIUM and GYPSUM application on growth and yield of WHEAT (Triticum aestivum L. cv. Tejan). Four levels of POTASSIUM (0, 0.4, 0.8 and 1.2 g pot-1 K20), three levels of GYPSUM (0, 1.75 and 3.5 g pot-1) and five levels of salinity of irrigation water including 0.8 (well water), 3, 6 9 and 12 dS/m (mixture of Caspian Sea water and well water) were applied in a completely randomized factorial design in a greenhouse experiment during 2002-2003 growing season. The results showed that increasing salinity of irrigation water, plant height, spike length, flag leaf area, total dry matter, number of spikes per pot, number of grain per spike, grain weight per spike, and 1000 grain weight decreased significantly (p<0.01). POTASSIUM application decreased the salinity hazards and improved grain yield and yield components. Interactive effects of POTASSIUM and SALINE WATER in total dry matter, 1000 grain weight and grain yield were significant at 1 % level. Furthermore, GYPSUM application had a positive effect on yield, total dry matter and 1000 grain weight. Interactive effects of salinity and GYPSUM in total dry matter and 1000 grain weight were significant at 5% level. Meanwhile, interactive effects of salinity, POTASSIUM and GYPSUM in 1000 grain weight and yield were significant at 1 % level.
