 ABSTRACT

The present study was conducted to know the rhizosphere microorganisms of maize as influenced by PGPR (Plant Growth Promoting Rhizomicroorgnisms) with different levels of inorganic fertilizers. Significantly the higher bacterial population at 30 (46.00 x 106 cfu/g soil), 60 (87.47 x 106 cfu/g soil), 90 (67.23 x 106 cfu/g soil) days after sowing and at harvest (57.53 x 106 cfu/g soil) stage was noticed in the treatment (T11) involving application of 100 % NPK + A. chroococcum + A. awamori + P. fluorescens. Whereas the higher the higher fungi and actinomycetes population at 30 (52.03 x 104 and 10.67 x 103 cfu/g soil), 60 (67.03 x 104 and 14.83 x 103 cfu/g soil), 90 (58.67 x 104 and 28.17 x 103 cfu/g soil) days after sowing and at harvest (33.90 x 104 and 27.67 x 103 cfu/g soil) stage was noticed in the treatment involving 100 % NPK + A. chroococcum + A. awamori + G. fasciculatum.

Keywords: A. chroococcum, A. awamori, P. fluorescens and G. fasciculatum.
