| Abstract | ||||
| Rice (Oryza sativa L.) grades a must-have cereal crop it rates the second weighty cereal crop moreover it's a salt-defenseless crop. Sulfur plays a basic role in plant development and growth processes. Potassium is the most rich cationic and essential nutrient. It is very important for crop yield and its tolerance to abiotic stresses. Is it possible that the effect of the interaction between them will be more effective in resisting salinity?. Two field experiments were operated on a clayey soil for two summer seasons .The treatments are a split-plot design included the influences of using agricultural sulfur without addition, 300 Kg ha-1 and 650 Kg ha-1 were applied on soil, while the sub plots were occupied by foliar applications of potassium as potassium citrate without addition, 36% and 45% . Sulfur application in soil and potassium foliar levels were improving plant height, no. of productive tillers hill-1, dry weigh, 1000-grains weight, grain yield, straw yield and NPK uptake of rice plant. Soil addition of sulfur was attributed positively in modifying bulk density (g cm-3) by reduced it, modifying total porosity % by increased it and features via decreasing pH, EC and ESP% in the soil. The interaction between sulfur and foliar potassium showed that applying sulfur (650 Kg ha-1) with potassium citrate (45%) together showed an effective impact on rice under salinity condition by improving growth, yield, N P K uptake and improving soil properties. | ||||
