Abstract

Water plays a very important role in the rice plant & In order to investigate the effects of irrigation methods & foliar application of nutrients on growth & yield, yield components & quality of rice, an experiment was conducted as split plots layouts based on a randomized complete block design with three replications & two factors including three irrigation methods (flooding, alternate wetting & drying & Saturating) in the main plots & foliar spray in six levels (normal water, nitrogen, nitrogen + potassium, nitrogen + potassium + zinc, nitrogen + potassium + zinc + boron & nitrogen + potassium + zinc + boron + molybdenum) in the sub plots during 2018, in rice research institute, the deputy of Mazandaran (Amol) was executed on a national cultivar. The results showed that among of irrigation method, fertilizer & their interaction, paddy yield & percentage of amylose were significantly at (p<0.01) percent & other qualitative traits were significant at (p<0.01) percent. the highest number of floret per panicle (198.73) & full grain (167.15), & Percentage of amylose (21/67%) were obtained in saturated irrigation. The highest yield of paddy with an average of 6643.07 kg.ha-1 in saturated irrigation under normal water foliar application and drought & moisture. irrigation under nitrogen + potassium + zinc foliar irrigation with an average of 6163.13 kg.ha-1 compared to the control was obtained as the superior treatment in Similar conditions were selected for this study.
