| Abstract | ||||
| The experiments were conducted at, the Forage Research Department, FeRI, Giza station, (ARC), during summer seasons 2001 and 2002 to evaluate the effect of different strains or bacteria as biofertilizers on forage pearl millet. Inoculation treatments used in this investigation were combined with 50% of N-recommended dose (60 kg N/fed). The obtained results proved that the use of biofertilizer especially with Azotobacter spp. + Azospirillum spp. and Bacillus megatherium + 8. po/ymyxa combined with 60 kg N/fed affected strongly the plant growth through the positive effect on fresh and dry forage yields (ton Ifed) at all cuts and seasonal yield. The same trend was obtained with plant height. number of tillers, roots dry weight and mineral content especially P and K as well as organic compounds, protein, fiber and ash yields. Pearl millet inoculated with Azotobacter spp. + Azosp < /em>iriJ/um spp. gave mean values comparable with those obtained when using the high dose or N-tertilization (120 kg N/fed). Thus, it saves about 50% of the required nitrogen which reduces costs and environmental pollution of mineral nitrogen fertilizer. | ||||
