Abstract :
Experiment on poldokhtar city located in the eastern miyankuh region in chemeshk village in cropping year 2017-18 with split plot in a randomized complete block design (RCBD) with drought stress in developmental stage 4 of coriander (control, stemming, flowering, and seed formation) as the main factor and bio-fertilizers as well as in the 4 levels (control, 50, 75 and 100 g/ha) as sub factor in making seed stained. In this experiment the interaction of drought stress and bio fertilizer phosphate barvar-2 are affected on other traits, vegetative and reproductive. with the progress of plant growth, less influenced by stress, fruit yield and seed (phonological stages). Also, with the change in the process of applying biofertilizer and drought stress, changed biological yield and harvest index, and indicated that the lack of water on stemming stage, the lowest impact on the transmission of the photosynthetic materials and in the final stages, reduced harvest index influenced by the stress. Thus, in this experiment was concluded that better use of the resources to grow and there reduce the negative effects must that be set to an appropriate biofertilizer, irrigation and consumption stage.
