A study has been undertaken during 1994-95 to analyze the cost structure al
ong with the size and productivity relationship in sericulture for differen
t districts of West Bengal. Cost of labour(both in moriculture and rearing)
is found to be the most important item and expenditure towards labour util
ization is comparatively higher for rearers having marginal land holding an
d causing negative net return for this group too. While establishing the si
ze and productivity relation, it is observed that though differences are th
ere, net return is optimized at mulberry land holding of 0.50 acre in most
of the districts at the existing production pattern.
