Abstract

In order to investigate the reaction of sunflower Iroflor cultivar to water deficit tension in different stages of growth and methods of biophosphate fertilizer consumption, a factorial experiment was conducted in a randomized complete blocks design with four replications. Water deficit tension in four levels including control (lack of water deficit tension ), tension in vegetative stage, tension in reproduction stage and tension in both vegetative and reproductive stages and application of bio phosphate in four levels including nonuse of biofertilizer, seed coated, topdress and and combined application of seed coated and topdress. The simple effect of water deficit tension and bio fertilizer on head diameter, grain number per head, one-thousand seed weight, biological yield, grain yield, oil percentage and oil yield were significant and their interaction was significant only on number of seeds per head, grain yield and oil percentage. The highest amount of traits among the levels of water tension was belonged to the control treatment (non-tension of water deficit) and among the application of biofertilizer to seed coated and top dress application simultaneously, which was observed in the weight of one thousand seed weight 42. 47 and 25. 67 grams, head diameter 67. 17 and 74. 16 centimeters, biological yield 43. 10165 and 74. 10596 kilogram per hectare and oil yield was 55. 1318 and 73. 1216 kilogram per hectare, respectively. The highest amount of traits in the number of seeds per head (51/950 ), grain yield (23/3451 kilogram per hectare) and oil percentage (68/47 percent) was obtained in combination treatment without water deficit tension and simultaneous application of bio fertilizer as coated seed and top dress. The effect of water deficit tension on the traits at the reproductive stage was significantly higher than the vegetative stage. Biofertilizer application treatment did not show significant difference in coated seed and top dress simultaneous application with application treatment in the form of coated seed. The resultof the experiment showed that the use of biophosphate fertilizer as coated seed in sunflower cultivar of Iroflor under normal and water deficit tension conditions has improved yield and studied traits.
