Abstract:
Two intensive bitter gourd cultivated area, Dhaka and Norshingdi districts were selected
for conducting the study, The data obtained for different characters were statistically
analyzed to find out the significance of the different farmers practices and chemical used
by the respondents' farmers on yield contributing characters, yield, economics return and
arthropod diversity in bitter gourd. In Dhaka district, the highest sample farmers
(33.00%) practiced FR1 and the lowest sample farmers (6.67%) practicing FP5 On the
other hand in Norshingdi district, the highest sample farmers (40.00%) practiced PP1 and
the lowest sample farmers (6.67%) practiced FR4. Fruit infestation by number and by
weight varied for different FPs. In Dhaka district, the lowest fruit infestation by number
and by weight was observed in FR5 (8.46% and 7.94% respectively) while it was the
highest by number and by weight (10.25% and 11.08% respectively) in FR1. In
Norshingdi district, the lowest fruit infestation by number and by weight was observed in
FR5 (8.061/6 and 8.13% respectively) while it was the highest by number and by weight
(11.08% and 10.49% respectively) in PP,. Considering the BCR for different farmers
practices in Dhaka district, it was maximum in FR, (2.28) while it was minimum (2.06) in
FP1. On the other hand in Norshingdi district, the BCR was maximum in FP, (2.10),
while it was minimum (1.85) in FR1. Similarly chemical used by respondent farmers in
Dhaka district, the highest sample farmers (33.33%) used IC2, while the lowest sample
farmers (6.67%) used IC4. On the other hand, in Norshingdi distric
respectively) while it was the highest by number and by weight (10,88% and 10.02%
respectively) in IC1. In terms of total fruit yield in Dhaka district, it was the highest in IC,
(23.92 i/ha), while it was the lowest (21.25 i/ha) in IC1. In Dhaka district, the BCR for the
combined use of different chemical was maximum in IC, (2.04), while it was minimum
(1.86) in IC1. On the other hand in Norshingdi district, the BCR was maximum in IC,
(2.06), while it was minimum (1.83) in IC1 .
