Fruit maturity and harvest
- Under favorable conditions, banana starts flowering in 9-12 months and
- Fruits matures in about 4-5 months depending upon varieties, climate etc.
- Banana are harvested at 3/4th maturity stage for distant markets or for chips making purpose while, for local markets are harvested at full maturity.
- The following are the indications of maturity of banana.
- Drying of top leaves.
- Changing of fruit colour from green to light green.
- The floral ends of fruits are shed with slight hand touch at apices.
- Fruit become plumpy and angles are filled & disappear.
- One or two fruits ripe at the basal end (yellow colour).
- Harvested when Starch content of the fruit (22-25%).

Yield:
- Yield of banana varies with variety and production practices.
- Tall cultivars usually yield 15-20 tones/ha.
- Cavendish group varieties yield about 40t/ha,
- Whereas the hill banana/cooking varieties yield about 11-15 tones/ha.
Â
Post-harvest management:
- Banana can be stored at about 13°C with the Relative Humidity of 85-95 % for 3 weeks and is ripened in a week at 16.5-21.0°C.
- The fruits should not be stored / shifted under refrigerated condition.
- The storage life can be increased by keeping the fruits in high concentration of carbon dioxide and low concentration of oxygen.
- Also storing in sealed polythene bags containing ethylene absorbent like potassium permanganate.
- Shrink film wrapping or Waxol (12 %) treatment can extend shelf life up to 3 weeks.
- Bananas are not usually allowed to ripen on the tree.
Â
Ripening of Banana
- Smoking has to be done with straw leaves & cow dung in a closed chamber for 18-24 hours in summer and 48 hours in winter and later shifted to ventilated room for uniform ripening.
- The exogenous application of 100 ppm ethylene gas in an enclosed chamber for 24 hrs. for will produce uniform color and ripening.
