Abstract :
This research was done to investigate the effect of irrigation intervals and organic fertilizer levels on yield and yield components of Hashemi rice in Guilan province. The experiment was done as split plots in the basis of randomized complete block design in three replications in the crop year of 2022 in Guilan province. The main factor included irrigation intervals (3 and 12 days) and the secondary factor included poultry manure at levels (0, 1000, 1500 and 4000 kg/ha). The results of research showed that the effect of irrigation and poultry manure at the level of 1% on paddy, straw and biological yields, plant height, number of productive tillers, length of panicle and weight of a single panicle were significant. Interaction effect of irrigation and poultry manure on the number of productive tillers and the weight of a single panicle was significant at the 1% level, but it was not significant on the height of the plant and the length of the panicle per plant. The highest number of tillers per plant and weight of a single panicle were obtained by the interaction effect of irrigation and poultry manure in irrigation intervals of 3 days and consumption of 1500 kg/ha with an average of 588 and 1.4 g, respectively. The interaction effect of irrigation and organic poultry manure demonstrated that, irrigation Interval 3 days and consumption of 1500 kg/ha organic poultry manure gained the highest yield of paddy, straw and biological yield were respectively with an average of 5957.5, 4613.8 and 10571.3 kg/ha.
