Eight treatments were used included (Control , Azotobacter , pseudomonas, Azotobacter +psuedomonas , Compost , Azotobacter + Compost , Compost + psuedomonas , Azotobacter + psuedomonas + Compost).

Complete Randomized Design ( CRD ) with 5 replicates was used.

Results showed that application of di bacterial bio-fertilizer (AP) increased significantly dry mater weight and N , P , K nutrients content for shoots with an increment of 36.4%,74.4%,76.0% and 64.9% respectively compared to control.
