Effect of vermicompost on the growth and yield of green gram (Phaseolus aureus Roxb.)

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, ro ot length, number of root nodules, fresh weight, dry weight, and yield perf ormance of P. aureus were observed on the 25th, 50th, and 75th day. The che mical analysis showed a higher content of N, P, and K in the vermicompost o f green gram pods (GGP) + cow dung mixture (1:1). Maximum growth and reprod uction of E. eugeniae were also recorded in GGP + cow dung mixture. The ger mination efficiency of P. aureus was 93.33% in the vermicompost-applied pot s compared to 84.17% in the control, i.e., biodigested slurry (BDS). The gr owth and yield performance of P. aureus in vermicompost were also significa ntly higher than the control.
