Abstract

Thirty phosphate solubilizing  bacteria (PSB) were isolated from rhizosphere of maize crop  from different maize growing areas of Kashmir valley by serial dilution technique  using Pikovskaya’s  agar  medium  and were compared with one another for P-solubilization, production of iaa and ga (growth promoting substances), siderophore production and ammonia production. The PSB (K4) proved to be the most efficient strain and was identified as Pseudomonas sp. On screening the isolate  recorded maximum phosphorus solubilization (60.00 µg ml-1), produced highest amount of IAA (36.07 µ mol ml-1) and GA (38.20 µ mol ml-1) which was significantly superior over all other isolates and thus can be exploited as biofertilizer. The isolate also showed ammonia and high siderophore production.
