Effect of vermicompost on the growth and yield of green gram (Phaseolus aureus Roxb.). (143)
Vermicompost was prepared from the initially decomposed pods of green gram (Phaseolus aureus Roxb.) using the earthworm Eudrilus eugeniae for 50 days. The effect of the vermicompost on germination efficiency, shoot length, root length, number of root nodules, fresh weight, dry weight, and yield performance of P. aureus were observed on the 25th, 50th, and 75th day. The chemical analysis showed a higher content of N, P, and K in the vermicompost of green gram pods (GGP) + cow dung mixture (1:1). Maximum growth and reproduction of E. eugeniae were also recorded in GGP + cow dung mixture. The germination efficiency of P. aureus was 93.33% in the vermicompost-applied pots compared to 84.17% in the control, i.e., biodigested slurry (BDS). The growth and yield performance of P. aureus in vermicompost were also significantly higher than the control.
