And after removing diseased and male plants 1500 plants remain per hectare. Approximately 1200 kg of latex can be obtained from these 1500 plants. If price of latex is Rs. 40 per kg there is profit of Rs. 48,000 per hectare only from latex. Besides this approximately Rs. 60,000 can be obtained by marketing the fruits. Earning from latex and fruits Rs.1, 08,000. Production of fruits and latex can be obtained upto two years thus there is a profit of Rs. 70,000. Considering total expenditure (approximately) Rs. 38,000 there is profit of Rs. 35,000 per year. Thus papain production is profitable.
