Abstract
The phosphate solubilizing and competitive saprophytic ability of certain bacteria and fungi assiciated with coconut based cropping systems were studied. The population of phosphate solubilizing bacteria were higher in coconut based high density multispecies cropping, multistorey ed cropping and mixed farming systems as compared to that in coconut monocrop. Bacillus, Pseudo-monas and Micrococcus and Aspergillus, Fusarium and Penicillium were the genera of F-solubilizing bacteria and fungi identified. No seasonal variation in the population of P-solubilizing bacteria and fungi was recorded. Bacillus polymyxa (45.2%), Bacillus subtilis (40.8%) and Pseudomonas striata (43.3%) were the bacteria which showed greater F-solubilizing ability under in vitro conditions. Among the fungi, Aspergillus niger (2 isolates) an Penicillium citrinum have recorded higher P-solubilizing ability. Aspergillus niger and Penicillum citrinum have shown greater competitive saprophytic ability, while Bacillus subtilis. Bacillus polymyxa and Pseudomonas striata showed better survival in sandy loam soil.
