Abstarct: d The high cost of labor, recent droughts and high water use in rice cultivation led to increasing the tendency of farmers to direct seeding and dry-bed seeding. Therefore, it seems necessary to pay attention to the practical method that reduces the amount of water required by the plant to create stress in the growth and yield stages of rice.This study was conducted to investigate the effect of irrigation cycle, foliar application and seed pretreatment with potassium silicate and calcium silicate in arid conditions on growth, yield and yield components of rice cultivar Fajr cultivar in 2019 crop year in an agricultural field in Aliabad Katoul province. The experiment was performed as a split plot-factorial baxsed on a randomized complete block design with 3 replications. Irrigation as the main factor in two levels (once every three days and once in six days) and a secondary factor of combining different levels of seed pretreatment in three levels (no pretreatment, pretreatment with potassium silicate and pretreatment with silicate Calcium) and foliar application at three levels (no foliar application, potassium silicate foliar application and calcium silicate foliar application) were applied in subplots.Pre-treatment was performed simultaneously with sowing seeds and spraying at the time of tillering. Sampling was done in two stages of flowering and harvest stage. The results of this study showed that increasing irrigation intervals (irrigation from three to six days) reduced plant height, stem diameter, dry weight of stems and leaves, the total number of seeds, leaf area index, the 1000-seed weight. Irrigation with a three-day interval also increased grain yield by about 12%, biological yield by 13.6%, membrane stability index by 3.95% and the relative leaf water content increased by about 10% compared to six-day irrigation. The results of this study showed that foliar application of potassium silicate increased plant height, number of tillers, dry weight of stems and leaves, and other studied traits. Also, foliar application of potassium silicate increased 1000-seed weight and yield by 8% and 27.12%, respectively. Seed pretreatment with potassium silicate also increased grain yield by 48% and 1000-seed weight by 5% and had a positive effect on other traits. The effect of foliar spraying and seed pretreatment with calcium silicate on grain yield and 1000-grain weight was also significant and ranked second statistically. Overall, in terms of the studied traits, seed pretreatment and foliar application with potassium silicate showed better results.
