| Popis: | The efficacy of a liquid formulation of “PGPR mix-I″ amended with 15 mM treahoalose, and a talc based formulation of the same were tested for plant growth promotion in amaranthus crop in sterilized soil under glass house conditions. The seven treatments included 100% NPK as per Kerala Agricultural University recommendation as chemical fertilizer alone, talc based or liquid formulation of PGPR mix–I each alone and with 100% and 50% NPK, control with additive without plant growth promoting rhizobacteria and absolute control. Liquid formulation of PGPR mix–I was found to be equally effective as talc based formulation of PGPR mix–I along with 100% NPK chemical fertilizers in enhancing yield and other biometric parameters of amaranthus. Application of PGPR mix–I under 50% supply of NPK as chemical fertilizers was found to be on par with chemical fertilizer alone at 100% dose. Our results indicate that a saving of 50 percent of chemical fertilizer supply is possible by application of the improved formulation of PGPR mix-I in amaranthus. |
