The objective of this study was evaluated the effect of combination of biological and chemical fertilizers on yield and yield components of common bean (Phaseolus vulgaris L.). The experiment was carried out as factorial in RCBD with three replications at Lahijan city during 2013. Treatments were including: 1- nitrogen fertilizer at three levels (0, 50 and 100 percent of recommended value), 2- Phosphorus fertilizer at three levels (0, 50 and 100 percent of recommended value) and 3- Biological fertilizer at two levels (with and without boifertilizer). The analysis of variance showed that experimental treatments had significantly effect on yield and yield components. Mean comparisons showed that the highest seed yield was obtained in 100 percent nitrogen fertilizer×50 percent phosphorus fertilizer×with biological fertilizer.
