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 rice crop (Oryza sativa L.) in 2017. The field experiment was laid out in Randomized Block Design with 10 treatments and three replications. It is evident that there is increase in plant height from 79.37 to 99.60 in Control to T10. It was higher in treatment T10 (Biochar + carpet waste + FYM (2+1+1 t) ha-1 + PGPR) 99.60cm followed by T9 (BC1 + CW1 + FYM1 t ha-1 + PGPR) 96.53. Significant differences were found between the treatments after application of PGPR in plot. There was a significant increase in the chlorophyll content of the rice crop. The maximum chlorophyll content in rice leaf was found in T10 (Biochar + carpet waste + FYM (2+1+1 t) ha-1 + PGPR) i.e. 45.93 followed by T7 (BC1 + CW1 + FYM1 t ha-1 + PGPR).In treatment T2 ( BC1 + CW1 t ha-1) increase in chlorophyll over control was 2.20% , while T6 (PGPR) increased 12.77% and in T10 (Biochar + carpet waste + FYM (2+1+1 t) ha-1 + PGPR) increased 23.76%. Application of graded level of biochar, carpet waste FYM and PGPR was found to significantly enhance the straw and grain yield of rice. Application of BC2, CW1 FYM1 and PGPR was found 60.17% higher over the treatment T1 (control). Grain and straw yield of rice significantly increased with the application of graded level BC, CW, FYM and PGPR the increase was found 92.8% higher over control T1.It can be concluded that using of these organic sources has good impact on the soil health under long term.
