摘要

Human labour was an important item in cocoon production starting from harvesting of leaves to nurse the worm throughout the day and night during the rearing period. It may be observed that total value of human labour was Rs.8419 (22.69% of total cost)for all farms. Total cost of silk cocoon production and gross returns per hectare were Rs.37103 and Rs.54298 for all farms. The cost of cocoon production has indicted an inverse relationship with that of farm sizes indicating that small farmers are better in containing the costs with their personal care. The MVP to opportunity cost ratio for all farms the cost of disinfectants was -1.82 which was highest and negative and suggests to reduce the expenditure on this input for realise more gross income.
