Efficacy of AMF and PGPR Inoculants on Maize (Zea mays L.) Plant Growth and Their Rhizosphere Soil Properties

Field trial was carried out using microbial inoculants through arbuscular mycorrhizal fungi and plant growth-promoting rhizobacteria. The inoculants were applied individually and also different combination in Zea mays. L (Maize), and plants were grown in the Department of Microbiology experimental garden, Bharathidasan University, Tiruchirappalli, Tamilnadu, India. In this context, the microbial equilibrium influence on the growth and development of maize plants is studied for every 15-day period of harvest up to 75 days. The dual inoculation treatment (T4 and T5) significantly increased microbial biomass and NPK accumulation in soil, and these dually inoculated plants displayed higher specific activity than their comparable to control. From all the treatments, comparatively the combined treatment of (T6) showed an active maize growth through the periodic analysis of chlorophyll, carbohydrate, protein, metabolite synthesize like phenol and flavonoids. It is concluded that T6 has a stimulatory effect on mycorrhizal root colonization and also improve the maize plant growth and soil properties.
