Harvesting
Banana should be harvested at the physiological maturity stage for better post harvest quality. The fruit is climacteric and can reach consumption stage after ripening operation
Maturity indices
These are established on the basis of fruit shape, angularity, grade or diameter of the median figure of the second hand, starch content and number of days that have elapsed after flowering. Market preferences can also affect the decision for harvesting a slight or full mature fruit.
Removal of bunch
Bunch should be harvested when figures of second hand from top are 3/4 rounded with the help of sharp sickle 30cm above the first hand. Harvest may be delayed upto 100-110 days after opening of the first hand. Harvested bunch should generally be collected in well padded tray or basket and brought to the collection site. Bunches should be kept out of light after harvest, since this hastens ripening and softening.
For local consumption, hands are often left on stalks and sold to retailers.
For export, hands are cut into units of 4-16 fingers, graded for both length and girth, and carefully placed in polylined boxes to hold different weight depending on export requirements.
Post harvest operations
At collection site injured and over mature fruits are discarded and for local market bunches should be delivered through lorries or wagons. However, for more sophisticated and export market where the quality is predominant, bunches should be dehanded, fruits are cleared in running water or dilute sodium hypochlorite solution to remove the latex and treated with thiobendasole; air dried and graded on the basis of size of fingers as already stated, packed in ventilated CFB boxes of 14.5 kg capacity or as per requirement with polythene lining and pre-cooled at 13-15ºC temperature and at 80-90% RH.
Such material should than be sent under cool chain at 13ºC for marketing
Yield
The planted crop gets ready for harvest within 11-12 months of planting. First ratoon crop would be ready by 8-10 month from the harvesting of the main crop and second ratoon by 8-9 months after the second crop.
Thus over a period to 28-30 months, it is possible to harvest three crops i.e. one main crop and two ratoon crops. Under drip irrigation combined with Fertigation yield of Banana as high as 100 T/ha can be obtained with the help of tissue culture technique, even similar yield in the ratoon crops can be achieved if the crop is managed well.
