Biofertilizer effect on growth of sugarcane (Saccharum officinarum L.) cultivated in Barak Valley, Assam Science

The aim of this study is to evaluate the effect of Azotobacter vinelandii, Paenibacillus polymyxa and Pseudomonas fluorescens isolated from rhizosphere of field-grown sugarcane in Barak Valley, Assam, as nitrogen biofertilizer on sugarcane plant growth under pot experiment condition. Four types of treatment i.e control with no inoculums (T0), Azotobacter vinelandii (T1), Paenibacillus polymyxa (T2), Pseudomonas fluorescens (T3) were used as biofertilizer. The difference in the growth among different treatment is found to be statistically significant at 5% significance level.
