Experimental design was a split plot based on a randomized complete block design with four replications. The treatments consisted of three deficit irrigation regimes (main plots) and six soil fertilizing systems (sub-plots). The irrigation treatments were included non-stressed, medium stress and severe stress. Fertilizing systems consisted of no fertilizing as control, phosphorous and nitrogen biofertilizers, 100% chemical fertilizer, vermicompost, 50% chemical fertilizer + 50% vermicompost, and 50% chemical fertilizer + biofertilizer as the sub plots. Integrated application of chemical and organic fertilizers increased soil P more than the other fertilizing systems. Integrated fertilizers increased plant N in compare with other fertilizing systems. Fertilizers containing vermicompost had more soil organic carbon, nitrogen and phosphorus or plant N and P under water stress rather than the others. Biofertilizer increased soil and plant P content under normal irrigation. UR - https://jci.ut.ac.ir/article_36099.html L1 - https://jci.ut.ac.ir/article_36099_1ae3e7b9a67dccf4427b3af34fff4b88.pdf ER -
