The effect of vinyl mulched cultivation on storability of garlic and onion were studied comparatively. Low temperature storage loss of garlic from vinyl mulched field were less than those of no mulch field, while ambient temperature storage losses were similar to each other under various storage condition. In March next year, the losses of the vinyl mulched and the no mulch from Seosan were 76.66 % and 78.99 % for unsealed, 47.13 % and 47.22 % for sealed in 0.05mm P.E. respectively in ambient temperature door wall warehouse, while they were 44.70 % and 45.90 % for unsealed, 28.52 % and 30.38 % for P.E. sealed respectively in low temperature warehouse. The decrease of pyruvic acid content of no mulch Seosan garlic was less than the others. At the end of March, Seosan garlic contained more pyruvic acid of 67.8 micro moles/g and 66.0 micro moles/g respectively for unsealed and P.E. sealed, which decreased only by 6.5 % and 9.0 % from the initial contents. In the case of onion, storage losses of vinyl mulched were also less than those of the no mulch. The losses of the mulched and no mulch were respectively 65.66 % and 69.21 % in door wall warehouse and 17.60 % and 19.48 % in low temperature warehouse. Pyruvic acid contents in March, next year were about 8 micro moles/g, decreased by 9-10 % from initial contents, without significant defferences between the mulched and no mulch
