Abstract

The use of chemical fertilizers for the growth of plants and other crops is harmful to the environment, causes pollution, time-consuming and is costly. The use of biological method to increase the yield of crops and plants is the best solution for this. The plant growth promoting rhizobacteria found near the rhizosphere region of the plants are able to increase the growth of plants by direct and indirect ways. The work here mentions the plant growth promoting rhizobacteria isolated from the rhizosphere region of wheat, sugarcane and maize. The isolated plant growth promoting rhizobacteria were checked for their ability for production of Indole-3-acetic acid, solubilization of potassium and zinc. The pot experiments were also carried to check the effect of plant growth promoting rhizobacteria on the growth of Sorghum bicolor and Zea mays plants. By studying the morphological characteristics and biochemical tests and comparing with Bergey’s Manual of Determinative Bacteriology, the isolates were identified to belong to the genus Alcaligenes, Gluconobacter and Saccharococcus and Acinetobacter sp. It is found out of eight prominent isolates, five isolates were able to produce Indole-3-acetic acid and three of the isolates were able to solubilize zinc and potassium. The isolates were found to increase the root and shoot length and also the percentage of seed germination was increased when compared with the control. The work is significant as this is biological approach for the growth of plants and crops and also it will be eco-friendly, economical, fast and having sustainable approach.
