In order to investigate the effect of integrated application of biological and organic fertilizers on absorption and phosphorus physiological efficiency in medicago sativa in Aran and Bidgol citiy in 2013, A factorial experiment was conducted in a randomized complete block design with three replications. Experimental factors include four levels of biofertilizers (control, nitroxin fertilizer, Fertilizer Phosphate-2 and the combination of Nitroxin and Fertilizer Phosphate-2) and Four levels of organic fertilizer (control, cow manure, sheep manure and chicken manure) were 10 tons per hectare. The results showed that the use of biological fertilizers had a significant effect on plant height, stem dry weight, leaf dry weight, leaf-to-stem ratio, grain yield, biological yield and harvest index at a significant level of 1%. Also, the effect of organic fertilizers on plant height, stem dry weight, leaf dry weight, leaf-to-stem ratio, grain yield, biological yield, harvest index, physiological efficiency and phosphorus use efficiency were significant at 1% level. Among the comparison of the averages of intraction effects, the highest physiological efficiency of phosphorus related to the treatment (no inoculation with biological fertilizer + consumption of 10 tons per hectare of cow manure) with an average of 35.78 kg of grains produced per kg of phosphorus used and the lowest amount of physiological efficiency of phosphorus. It belonged to the treatment (not using biological fertilizer + not using organic fertilizer.
