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.

This experiment was performed based on split plot in RCBD with three replications in Minab Agricultural Research Station during two successive years. Main plots were allocated to planting method (basin and furrow) and sub plot to four Onion cultivars (‘Primavera’, ‘White Early Grano 502’, ‘HT3544’ and ‘HT3560’). Nursering was done in October and the transplants were transferred to main land in December. All plots were irrigated based on finding of previous studies. Finally was recorded the characters such as bulb yield, multi-center percent, length and diameter of bulb, bulb shape index, bulb weight and time of bulb producing and harvesting. Results showed that planting method had significant influence on bulb yield. Bulb yield of basin method was 28% more than furrow method and had significant difference together. The greatest bulb yield was observed in ‘HT3560’ cultivar and the least in ‘WEG502’ cultivar without any significant difference. ‘WEG502’ cultivar also was harvested 18 days later than other cultivars in two years and it had multi-center percent more than other cultivars. Generally two new cultivars (‘HT3544’ and ‘HT3560’) were better than dominant cultivated cultivars (‘Primavera’ and ‘WEG502’) in two years of experiment.
