Production of healthy seedling is a must for successful plant production. This paper deals with the evaluation of the effects of five different vermicompost applied at four different concentrations on seed germination and seedling quality of Solanum melongena var. arka keshav and mayalu in laboratory and greenhouse conditions. The experiments were conducted in a complete randomized design with twenty treatments and control per variety. Germination %, seedling length, seedling biomass, and seed vigour index (SVI) were measured at the end of the experiment. Vermicompost application improved all the parameters in both environmental conditions except seed germination that decreased with increasing vermicompost concentration. Vermicompost sample V2 and control produced the highest seedling quality in var. arka keshav and mayalu, respectively. Vermicompost had an inhibitory effect on seedling quality at laboratory condition in both varieties. Conversely, in greenhouse condition, vermicompost sample V1 yielded highest SVI of 1340.15 in arka keshav and 1225.66 in mayalu. Highest vermicompost concentration yielded the best quality seedling with SVI of 1219.88 and 1153.56 in var. arka keshav and mayalu, respectively. This suggested an important role of vermicompost concentration in growing media for enhanced seedling quality. The findings also suggested that favourable pH for developing seedlings of S. melongena is slightly acidic. The study firmly concludes that vermicompost differentially affects seedling growth and quality according to the concentrations and seed variety.
