Selection of Carrier Materials to Formulate Bioinoculant Package for Promoting Seed Germination

Abstract

Biofertilizers are a novel technique for Indian agriculture that has the potential to address many of the shortcomings of chemical-based technology. Plant growth-promoting (PGP) traits such as IAA, P-solubilization, ACC deaminase, NH3, HCN, EPS, siderophore synthesis, and biofilm formation have been demonstrated in two salt-tolerant PGPR, BST YS1 42 (Bacillus cereus) and CHR JH203 (Bacillus marisflavi). They are most commonly utilized to make carrier-based compositions. This study aimed to evaluate how different carrier-based formulations of salt-tolerant PGPR performed in seedlings of pea and maize plants. The chosen PGPR was mass replicated in the lab and put into seedlings via a variety of carriers, including charcoal powder, dry pea peel powder, tea leaf powder, hay+2%peptone, and cowdung powder. The influence of bio inoculants on seedling growth of Pisum sativum and Zea mays seedlings was investigated. There was a substantial variation in seedling germination in both pea and maize. The result was different depending on the type of carrier materials utilized in the bioformulation process. The results showed that seedling germination was better with the bioformulation made with charcoal and tea leaf powder. As a result, we believe it might be used to alleviate abiotic stresses in a cost-effective and environmentally friendly manner.
