Abstract:

Land recovery may expand the supply of usable land for food security. Immature soil is not conducive to plant growth and needs to be amended with organic matter and plant growth-promoting (PGP) microorganisms. The study evaluates the influence of biofertilizer combinations on the growth and yield of brinjal (Solanum melongena L.) cultivated using garden and rhizospheric soils from Raipur, Chhattisgarh. Soil samples were analysed for physio-chemical properties, and pot culture experiments were conducted using Azospirillum brasilense, Bacillus megaterium, and B. circulans, individually and in combinations, along with Phosphate-solubilising Bacteria (PSB), VAM, and NPK fertilizers. Significant improvements were observed in plant height like T3 (18.24 cm), closely followed by T12 (17.66 cm) and T9 (17.24 cm), branching like primary branches (20.56), while T3 (18.78) and T12 (18.14) recorded the highest secondary branches, fruit length, width, fruit number, and yield. Overall, these Results revealed the potentiality combination of particularly PSB + VAM + Azospirillum + Bacillus megaterium + B. circulans + NPK, which have consequence to enhance all measured biofertilizer parameters in the field of Agriculture and they can also be used as an alternative chemical phosphate fertilizer in Raipur, Chhattisgarh.
