Rhizobacterial Inoculation Effect On Yield Contributing Parameters Of Maize (Zea Mays)

Abstract

Increasing prices of synthetic fertilizers are posing a grave threat to world’s agriculture. The use of alternate ways to
minimize the use of synthetic fertilizers without compromising yields is the fundamental objective of today’s
research. Use of beneficial microbes in agriculture is among the methods to minimize the risk. To address the
problem two trials were conducted to investigate the effects of plant growth-promoting rhizobacteria (PGPR) on
percent germination, vigour, and other parameters of pot-grown maize. In these trials, four bacterial strains,
including P. aeruginosa, P. putida, E. mori, and E. asburiae. P. aeruginosa, P. putida, E. mori, and E. asburiae were
the microorganisms used. The results of the first investigation revealed that seed Inoculation greatly increased the
germination of maize seed and the vigour of maize seedlings. In the second experiment, bacterial inoculation
followed by a considerable rise in the dry weight of the shoots, as well as the surface area of the leaves. The findings
revealed that inoculating seeds with rhizobacteria had an additional encouraging influence on the growth and
development of the plants than other treatments. Seeds Inoculation with rhizobacterial strains resulted in
considerable increase in plant height, fresh biomass, dry biomass, and leaf area of the maize plants in this
experiment, as demonstrated in results.
