During 20011 2002 and 20021 2003 seasons. three biofertilizers namely
Biogen, Microbene and Nitrobene. each at 100 to 300 g f plant aside mineral N source
at the fixed rate of N l.e. 500g f plant were tested for their effect on growth and fruiting
of Grand Naine banana plants. Results showed that biofertilization with Blogen. Microbene and Nitrobene
each at 100 to 300 g 1 plant • In descending order was effective In enhancing growth
characters. laaf contents of N. P and K. bunch weight, weights of hand and finger •
pulp! peel ratio. total soluble solids % , total and reducing sugars % and in decreasing
the total acidity compared to unbiofertillztlon. There was unfavourable effects on
growth characters. yield and fruit Cjuality with Increasing the amount of biofertilizers
from 200 to 300 gI plant. Percentage of starch did not change with the present
treatments. It is necessary for biofertilizing Grande Naine banana plants with Biogen at
200g and 300 9 N in any mineral source I plant 10 improve the yield and fruit quality.
