The use of biological and organic fertilizers as alternatives to chemical fertilizers increases the efficiency of the cycle of food elements, improves and stabilizes the quantitative and qualitative grain yield by maintaining the appropriate productivity of soil and water resources in sustainable agriculture. This experiment was conducted to determine the effects of combined application of organic and biological fertilizers on nitrogen agronomy efficiency and phosphorus content of white bean (Phaseolus vulgaris L.) in 2015. The study was conducted as a factorial experiment arranged in a randomized complete blocks design with three replications. Treatments included four organic fertilizers (control, farmyard manure, mushroom compost, and vermicompost) and four biofertilizers (control, inoculation with azotobacter, barvar2, and azotobacter+ barvar-2). Application of nitroxin biofertilizer had the highest effect on all traits. The highest protein yield (2779 kg ha-1) related to nitroxin biofertilizer treatment + organic control and the lowest one (950 kg ha-1) was obtained when no organic and biofertilizers were applied. The highest and the lowest of phosphorus content (2.34% and 1.03%) belonged to nitroxine + mushroom compost and Barvar-2 + organic control, respectively. The highest (11.53 kg kg-1) and the lowest (0.0001 kg kg-1) nitrogen use efficiency (NUE) were achieved in control treatment + animal manure and when no organic and biofertilizers were applied, respectively. Therefore, the highest (11.53 kg kg-1) and the lowest (0.0001 kg kg-1) NUE were obtained in control + animal fertilizers and when no fertilzers were applied. Considering that the simultaneous application of biological fertilizers (nitroxin + Barvar-2) and animal manure is superior in terms of grain harvest index (35%), therefore, it was more priority and recommendable in the region
