One of the vital components to achieve sustainable agriculture is integrated plant nutrition through using organic and biofertilizers in. A lot of researches have been conducted regarding the tolerance of different varieties of pistachio (Pistacia vera) to drought and salinity; however, limited researches are focused on the reaction of various varieties to organic and biofertilizers. For this purpose, a greenhouse experiment was performed in Vali-e- Asr University of Rafsanjan in 2015 as a completely randomized factorial design in three replications. In this study, treatments included surface sterilized and germinated seeds of pistachio in two varieties (Badamie-riz Zarand and Qazvini), three levels of bacteria (inoculated with D6 and D12 isolates of Fluorescent pseudomonads and non-inoculated) and three organic manure application rates (0, 2 and 4 % w/w). The treatments were replicated three times and arranged totally in 54 pots. Application of cow manure and fluorescent psudomonads increased growth and nutrient uptake Badamie-riz Zarand and Qazvini pistachio varieties. In this research the increment of measured parameters in two pistachio varieties in comparison with controls (with no application of organic and biofertilizers) were considered as response and then two varieties responses were statistically compared together. The application of manure and Fluorescent pseudomonads promoted the growth and nutrient uptake in both varieties. Comparing of two varieties showed that using bacteria compared with significantly increased phosphorus, iron and zinc uptake in Qazvini (Q) variety in comparison with Badami-rizZarand (B) variety. Response of Qazvini to application of cow manure was better and the applied manure treatments could significantly enhance nitrogen, phosphorus and copper uptake up to 61, 189 and 490 percent (P <0.05) respectively in Q variety compared to B variety. The combined application of bacteria and manure also significantly raised shoot dry weight, the uptake of iron, zinc, copper, phosphorus, calcium and nitrogen in Q variety compared to B variety. The results of this study indicated that the reaction of these two varieties of pistachio to the application of manure and growth promoting bacteria was different. Q variety demonstrated better results using organic fertilizer, biofertilizers and combined application compared to B variety. Accordingly, it seems that beyond considering the tolerance of varieties to salinity and drought and some other cases, the response of varieties to organic and biofertilizers should be considered toward sustainable agriculture and production of higher- quality products.
