Screening of the selected formulations of a microbial consortium for their effectiveness on the growth of finger millet (Eleusine coracana L. Gaertn.)

Abstract

A Greenhouse investigation was carried out to screen the effectiveness of selected four formulations (alginate based, fluid bed dryer based, lignite and liquid formulations) of Agriculturally Important Microorganisms (AIMs) viz., Azotobacter chroococcum., Bacillus megaterium and Pseudomonas fluorescens on growth parameters of finger millet (Eleusine coracana L. gaertn.). As a result, the plant growth parameters such as higher plant height (38.93 cm), maximum number of leaves (9.67), total chlorophyll content (2.54mg/g of leaf), total nitrogen uptake (103.56mg/ plant), total phosphorus uptake (63.11mg/plant) and total biomass content (12.87g/plant) were recorded in plants treated with triple inoculants in liquid formulation. The present study revealed that the triple inoculants in liquid formulation contributed more to the growth attributes and nutrient uptake compared to the other test formulations used in the present study.
