I am student pursuing my bachelors degree in Agricultural and Food Engineering at IIT Kharagpur, India’s premier research organization. I am working on developing a fruit picking machine for mango. I have studied the already existing machines in India. I am interested to know the economics involved in picking mangoes. I am seeking answers to the question like How many trees on an average are there in one acre land. What is the average no. of fruits on a tree. how many labours are employed for picking in one acre per day. What is the labour wage. How long is harvesting season. And what is the preferred mode of picking, Hand picking or by pole. Any/All suggestions are welcome.
