bacteria Azotobacter Chrococcum and phosphate dissolving
bacteria Bacillus megaterium (1:1 v/v). Bio-organic fertilizer
was applied to the plant once after 2, 5 and 8 weeks of transplanting
at the level of 10 ml/plant at concentration of
109 cell/ml. The mixture was injected near the root of the plants.
The bio-organic fertilizer was kindly supported by the Agriculture
Microbiology Department, National Research Centre.
