Variety of Rangin Sagar banana cultivated new sucker own land that is called Lichi (first cut) in Shibpur, Charghat, Rajshahi district. The latitute and longitute were found to be 24°36´06? and 88°74´79? respectively. Banana were harvested within 13 months after planting. The maturity parameters of banana such as firmness (74.46-81.35 N), °Brix (3.4), angularity (45.75-52.67°), colour parameters (L*, h°, C* as 47.12-52.82, 117.12-119.99, 27.88 respectively) were recorded.
Two hundred twenty bunches from orchard at Shibpur, Chargha and 50 bunches of banana (local Rangin Sagar) from Banesshar assemble market under Rajshahi district were purchased on 28 October 2019. Hands of bunches were separated by BARI developed dehandling tool from 150 bunches of banana for removing the latex from the crown of hands and later packaging and loaded them in track in heap. Hands were cleaned, sorted (over and under size, crack, spot) and graded (chosen of 2, 3,4,5,7 hands from each bunch out of 7-9 hands). Carton of 20 kg, plastic crate of 15 kg and wooden box of 20 were used for packaging the banana hands. They were packed in all packages with wrapping of news print paper, cling paper and without wrapping. One hundred hands and same quantity of bunches were heaped in track. They were transported from Rajshahi to Gazipur on 28 October 2019. Traveling distance and traveling duration was recorded to be 220 km and 5 hours (3.00pm to 8.00 am). Weight, colour, firmness, °Brix, temperature, relative humidity, oxygen, carbondyoxide in package and banana heaps, decay, fruits damage due to loading, unloading and transportation, shelf-life and condensation of packages and all cost estimation were recorded.
Peel colour measurement:
The peel colour was measured using a chroma meter. An 8 mm diameter measuring head mounted on the meter was calibrated each time with a standard white plate. Colour measurements were recorded using Hunter L*, a* and b* scale (Hunter, 1975; Francis, 1980). The "L*" coordinate is a measure of lightness (white-black and ranges from no reflection L=0 to perfect diffuse reflection *L=100), the "a*" scale ranges from negative values for green to positive values for red and the "b*" scale ranges from negative values for blue to positive values for yellow. The L*, a* and b* values were converted to hue value and chroma (McGuire, 1992). The C* represented the vividness of colours with values ranging from 0=least intense to 60 =most intense. The h° is actual or perceived colour that used to classify the kind of colour, which vary continuously from 0° to 360 °. A h° of 0 ° corresponded to h° of 270.
Firmness of banana:
Banana firmness was measured using digital firmness tester equipped with an 8 mm diameter cylindrical stainless probes. Tester was checked each day before use. The plunger was made to work in and out (about ten times) to ensure that it was running smoothly. Firmness was expressed in Newton (N). Three readings were taken at three places on the surface of each fruit and the mean value was calculated.
