Effects of Irrigation Methods and Nutrient Foliar on Yield, Yield Components, and Quality Characteristics of Rice‎

Water plays a very important role in the rice plant. In order to investigate the effects of irrigation methods and foliar application of nutrients on growth, yield, yield components, and quality of rice, an experiment has been conducted as split plots layouts based on a randomized complete block design with three replications and two factors including three irrigation methods (flooding, alternate wetting, drying, and Saturating) in the main plots as well as foliar spray in six levels (normal water, nitrogen, nitrogen+ potassium, nitrogen+ potassium+ zinc, nitrogen+ potassium+ zinc+ boron and nitrogen+ potassium+ zinc+ boron+ molybdenum) in the sub plots during 2018, in rice research institute, the deputy of Mazandaran (Amol), executed on a national cultivar. Results show that among irrigation method, fertilizer, and their interaction, paddy yield and percentage of amylose have been significantly at (p<0.01) percent with other qualitative traits being significant at (p<0.01) percent. The highest number of floret per panicle (198.73) and full grain (167.15), and percentage of amylose (21.67%) are obtained in saturated irrigation. The highest yield of paddy with an average of 6643.07 kg.ha-1 occurs in saturated irrigation under normal water foliar application and drought and moisture. Irrigation under nitrogen + potassium + zinc foliar irrigation with an average of 6163.13 kg.ha-1 compared to the control is obtained as the superior treatment in similar conditions were selected for this study.
