Evaluation of selected microbial consortium formulations on growth of green gram (Vigna radiata L.)

Abstract

A Greenhouse investigation was carried out to evaluate the selected formulations (alginate based, fluid bed dryer based, lignite and liquid formulations) of Agriculturally Important Microorganisms (AIMs) viz., Rhizobium sp., Bacillus megaterium and Pseudomonas fluorescens on growth and nutrient uptake of green gram (Vigna radiata L.). The plant growth parameters such as higher plant height (21.63 cm), maximum number of leaves (11.33), total chlorophyll content (3.08 mg/gm of leaf), total nitrogen uptake (81.36 mg/plant), total phosphorus uptake (12.42 mg/plant) and total biomass content (5.20 g/plant) were recorded in plants receiving triple inoculants in liquid formulation. The present study revealed that the microbial inoculants in liquid formulation influenced more growth and nutrient uptake when compared to other test formulations used in the present study.
