In the crop year of 2013, a test was conducted on the deputy farm ofRice Research Institute of the country -Amol, to investigate the foliar application effect of Nitrogen and Potassium major elements, on morphological and physiological features of Shirudi and Hashemi rice cultivars, as two split plots based on randomized complete block design with three replications. The main factor consisted of two Hashemi and Shirudi cultivars, and the subsidiary factor has been the number of foliar application and the subsidiary- subsidiary factor has been recommended and altered densities. In this experiment, agronomic and physiological features are measured; consisting chlorophyll content, remobilization of dry matter and plant analysis. The results of variance analysis showed that the figure effect and the interaction of the number of foliar application had a significant effect on the amount of chlorophyll at different densities. The results of related variance to remobilization on analysis showed that the figures’ interaction was significant on concentration and the interaction of foliar application on concentration in the feature of stem and whole organs at 1% probability level and in leaf at 5% probability level. Based on the results, it was determined that stem, leaf, and whole aerial parts’ of theory matter remobilization had significant differences. Among the studied features, Shirudi cultivar with recommended concentration and average performance of 6828 kg per hectare, and HashemiTarom cultivar in two stages of foliar application with the recommended concentration and 5533 kg per hectare had the highest rate of whole aerial parts 'remobilization. Shirudi had the lowest rate of remobilization at one level of foliar application with altered densities (5123). The result of the main elements of Hashemi and Shirudi Taroms’ Dordogne and stubble straw analysis showed that the amount of nitrogen and phosphorus of grain were more than its stubble straw and the amount of potassium in the stubble straw was more than its amount in grain. Comparison of average features showed that Shirudi cultivar with performance of 6666.1 kg per hectare was more than Hashemi Tarom cultivar with average performance of 3939.4 kg per hectare.
