The study was conducted on the assessment of artificial ripening practices by chemicals on the quality of tomato, banana and mango in selected area of Chapai Nowabgonj, Rajshahi, Jessore, Kustia and Modhupur. In these areas, the farmers and traders use different artificial ripening practices by chemicals for early ripening in mature/immature fruits and vegetables. In case of tomato, they use ethophane and ethrel in different doses having such brand name ripein-15, harvest, tomtom, riser, profit, perafix, ethrel, etc. Tomato is ripened within 6-8 days and shelf life is extended 25-30 days. In case of banana, the farmers use ripen-15, promote, profit, ethrel and calcium carbide for uniform and early ripening. It is riped within 2-3 days and shelf life is extended 1-2 days. Similarly, calcium carbide and ripen-15 are used in mango and it develop yellow colour within 2-3 days and also uneven ripening is observed in the fruit.

• To assess the current practices of various chemicals treatments used for ripening of tomatoes,,
bananas, mangoes, papayas, pineapples and jackfruits.
Physical survey were conducted in different areas of the country such as for mango Rajshahi, Chapai Nowabgonj and Meherpur, for banana Bogra, Modhupur and Kustia and for tomatoes Rajshahi, Chapai Nowabgonj, Jessore and Kustia. The farmers and traders were interviewed with a pre-selected questionnaire like usable different ripening chemicals, quantity of doses, shelf-life of treated fruits, development of fruit colour, storage of ripening fruits/vegetables and doses applying techniques, etc and collected information were recorded.

We can conclude from the above assessment of artificial ripening on the quality of tomato, banana and mango in selected areas, farmers and traders have no recommended doses of different ripening chemicals. It is necessary to standardize the doses and their residual effect of the ripening chemicals in the treated fruits/vegetables. So the assessment will be repeated for further study on other growing areas of chemically treated selected fruits and vegetable.
