Abstract

In order to investigate the analysis of growth indices and morphophysiological traits of Rice, an experiment in the form of statistical split plots design with three levels of irrigation and six foliar application with three replications was conducted at Deputy of Rice Research Institute (Mazandaran-Amol) in 2017. By measuring the total dry weight and leaf area six times during Rice growth, the trend of changes in growth indices was plotted by functional method relative to the day after transplanting. The results showed that the irrigation factor was significant in terms of paddy yield, biological yield and plant height at the level of one percent probability and in terms of the number of fertile tillers at the level of five percent. Fertilizer factor was not significant in any of the investigated traits. Irrigation and fertilizer interaction was significant in terms of paddy yield at five percent probability level and biological yield at one percent probability level. The highest yield of paddy with an average of 7284 kilogram per hectare and the lowest with an average of 4690 kilogram per hectare were related to submerged irrigation under nitrogen + potassium foliar application conditions and alternating drought and moisture irrigation under normal water foliar application conditions. The highest Leaf area index in saturated irrigation was obtained at the rate of (5. 27) and the lowest was related to alternating drought and moisture irrigation treatment at the rate of (4. 17) in Keshvari cultivar. Therefore, considering the achievement of maximum Leaf area index, total dry matter accumulation and crop growth rate in saturated irrigation, it can be suggested among Rice irrigation methods as a superior option under similar conditions to the present study.
