Results from 3-way ANOVA and Duncan's test of the effects of vegetable variety, (VV); fertilizer dose, (FD); fertilizer application time, (FAT): T1 at planting, T2 after planting; Telfairia occidentalis, TO; Solanum marcrocarpon, SM; Amaranthus viridis, AV; (0T-80T as fertilizer dosing treatments) on α-amylase inhibitory activity of vegetable leaf aqueous extracts.
