Studies on NPK Biofertilizer Consortia and their Influence on Maize (Zea mays L.) Seedling Vigour

Four local efficient biofertilizer strains namely, Gluconacetobacter G1 and Azospirillum ACD-15 as nitrogen fixers, Pseudomonas striata phosphorus solubilizing bacterium and a potassium were used in developing NPK consortia. Each consortia consisted of one the two fixing bacteria, phosphate (PSB) (KSB) bacteria five different formulations lignite, kaolinite, liquid, Na-alginate bentonite. These evaluated under in vitro on maize germination seedling vigour. Growth kinetics each strain was after their compatibility confirmed. The population four assessed at ambient conditions over 90 days. survival individual influence vigour to identify efficiency Among formulations, liquid supported significantly higher DAS. Liquid formulation recorded highest (94.25 per cent) (3850.43).
