Inoculation of Azospirillum significantly influenced the leaf : stem ratio (LSR) of Pennisetum trispecifio hybrid (P. typoides x P. purpureum x P. squmulatum), but its effect on number of tillers was not consistent. Application of nitrogen did not significantly influence the number of tillers,LSR and green forage yield during the first year. Inoculation of Azospirillum strain ACD 20 recorded significantly higher green forage yield than ACD 15 and the control. Theeincrease in green forage yield owing to inoculation of strain ACD 20 over ACD 15 was 18% and over the control was 25%. Azospirilium strain ACD 20 inoculation could give an equivalent green forage yield as given by application of 25 kg Wtha. The benefit : c s t ratio was maximum (2.35) when Azospirillum strain ACD 20 inoculated to .= was Pennisetum trispecific hybrid, followed by application of 75 kg Nlha (2.09) and 25 Kg Nlha (2.07).References
