BACTERIA ISOLATED FROM CULTIVATED SOIL AFTER LIMING PROMOTE SEED GERMINATION AND SEEDLING GROWTH OF CROP PLANTS
Abstract
Bacteria isolated from soil after liming, including strains like Acinetobacter junii and Serratia marcescens, were found to possess significant PGP capabilities. These activities included phosphate solubilization, production of indole-3-acetic acid (IAA), and nitrogen fixation. In laboratory tests, seeds of wheat, chickpeas, and rice treated with these bacteria exhibited significantly improved germination rates and greater root and shoot growth compared to untreated seeds. For example, Acinetobacter junii was shown to increase wheat germination by up to 99%.
