An experiment was conducted at Regional Horticultural
Research Station, Navsari Agricultural University, Navsari to
study the effect of bunch management and chemical treatments on
maturity, yield and quality of banana (Musa paradisiaca L.) cv.
„Grand Naine‟ during year 2014-15. Twelve treatment
combinations, consisting of three levels of hand management viz.,
7 hands per bunch (H ), 8 hands per bunch (H ) and 9 hands per
1 2
bunch (H ) and four chemical treatments viz., Control as no spray
3
(C ), Sulphate of potash (SOP) @ 1.5% (C ), GA @ 100 mg l-1
1 2 3
(C ) and Novel organic liquid fertilizer @ 2% (C ) was laid out in
3 4
factorial Randomized Block Design with three replications.
The banana bunches treated with hand management by
retaining the lower number of hands per bunch and sprayed with
sulphate of potash @ 2% shortened the maturity period of banana
cv. „Grand Naine‟. Number of fingers per bunch and fruit yield
were found maximum with more number of hands per bunch i.e. 9
hands per bunch. Chemical treatments were not affected the
number of fingers per bunch. Whereas fruit yield was found
maximum with GA 100 mg l-1 followed by Novel organic liquid
3
fertilizer @ 2%. Finger weight was maximum with 7 hands per
bunch with GA 100 mg l-1 of chemical spray. But overall fruit
3
yield was maximum with nine hands per bunch.
Pulp: skin ratio, total soluble solids, titrable acidity,
physiological loss in weight and shelf life of fruits were not
altered by hand management treatment as well as different
chemical spray in banana. There was improved in sugar content
and ascorbic acid content of fruit by spray application of GA 100
3
mg l-1. Hand management treatments were unaffected for the same.
An organoleptic evaluation of ripened banana fruit was found non-
significant by hand management treatment as well as chemical
spray on banana bunch. All interactions between bunch
management and chemical treatments failed to show any
significant effect for all above parameters.
On the basis of economics, nine hands per bunch and spray
application on bunch with GA 100 mg l-1 secured maximum net
3
realization i.e. Rs 82800/ha under paired row system of banana
planting.
From the above results, it can be concluded that maintaining
of 9 hands per bunch and spray with GA 100 mg l-1 on banana
3
bunch were found better for higher yield and net realization in
banana cv. „Grand Naine‟.
