This study was conducted in the two successive seasons of 1999/2000 and 2000/2001 at a private farm at Dahrout, Maghagha, Minia, Egypt. The present study aimed to investigate the effect of chemical fertilizers (Nitrogen and Phosphorus), biofertilizers (Rhizobium, biogene and phosphorein) and their interaction on the some growth characters and fresh yield and its components of two snap bean (Phaseolus vulgaris, l.) cultivars i.e, "Bronco" and "Giza 3". The obtained results indicated that "Bronco" cultivar was superior in plant height, number of branches, number of fresh pods per plant and total fresh yield (ton/fed.), while cv. Giza 3 was superior in weight of fresh pods/plant and average fresh pod weight. Bia-fertilizer treatments significantly increased most studied characters when compared with the uninoculated plants. Inoculation with Rhizopium produced the highest values followed by those of the biogene treatments. Most studied characters were significantly affected by the chemical fertilizers (N+P) treatments. The interaction among the studied factors had significant effects on most studied characters. Finally the obtained results showed that it may be recommended to grow plants of cv. " Bronco" after inoculation with the biofertilizers of N and P with about 50% of the recommended chemical fertilizer dose.
