The present investigation was aimed for improving growth and yield of crop using waste products of different activities and also useful in ecological stability of soil environment. The experiment was conducted in the organic farming plot of the Institute of Agricultural Sciences, BHU, Varanasi during kharif season of mungbean crop (Vigna radiata L.) in 2014. The field experiment was laid out in Randomized Block Design with 10 treatments and three replications. Application of graded level of biochar, carpet waste FYM and PGPR was found to significantly enhance the straw and grain yield of mungbean. Application of BC2, CW1 FYM1 and PGPR was found 60.17% higher over the treatment T1 (control).Grain and straw yield of mungbean significantly increased with the application of graded level BC, CW, FYM and PGPR. The available nitrogen content of soil ranged between 283.55 and 323.66kg ha-1, the minimum being in control (T1) and maximum in treatment T10 (BC2+ CW1+ FYM1 t ha-1+PGPR). Application BC in the soil resulted in increase soil EC, pH, OC but the increase was not significant. No interaction effects among BC, CW and PGPR were found to be non-significant in influencing the available phosphorus and potassium content of soil.
