Abstract: The present investigation was carried out at JNKVV, Jabalpur during summer season of 2019 to evaluate the performance of previously multiply of Pseudomonas(P) fluorescens at different temperature and pH value on nutrient content and their uptake by plant, nutrient availability and yield of maize (Zea mays L.). Treatments comprised of 16 isolated from fermentor under different temperature and pH (Temperature: 25, 28, 31, 34 0C and pH 6.7, 7.2, 7.7, 8.2) including two control FUI (fertilized + uninoculated) and UFUI (unfertilized + uninoculated). Results indicated that inoculation with different isolates had positive impact on total NPK content and their uptake by crop, NPK availability and yield of maize (grain and stover) comparing to FUI. The treatment combination T28+pH 7.2 (Temp 28 oC + pH 7.2) isolates significantly enhanced the grain and stover N (12.8 and 8.8%) and P (17 and 10.3%) content respectively, and the isolate of T31+pH 7.2 significantly increased K content in grain and stover (26.7 and 26.5%) respectively, over that of FUI. The treatment combination T28+pH 7.2 isolates significantly enhanced the total N and K uptake by plant (42.2 and 45.8%) respectively over that of FUI and the isolate of T31+pH 7.2 significantly increased total P content by plant (61.1%) over that of FUI. The treatment combination T28+pH 7.2 isolates significantly improvement in available N (16.0%), P (25.7%) and K (25.2%) content in soil after harvest of crop over that of FUI. The treatment combination T28 + pH 7.2 significantly increased the grain (24.9%) and stover yields (31.6%) of maize over that of FUI. This study demonstrates the application of P. fluorescens play a vital role for improving the NPK contents their uptake, nutrient availability and yield of maize.
