POTENTIALITY OF VEGETABLE PRODUCTION ON ROOFTOP GARDEN AT DIFFERENT LOCATIONS OF DHAKA CITY

Abstract

The experiment was conducted at the roof of four residential area of Dhaka city which are located at Mohammadpur, Kolabagan, Adabor and Dhanmondi during the period from October, 2018 to August, 2019. The experiment was laid out in Completely Randomized Design (CRD) having single factors with four replications. There were 16 unit plots in the experiment location. The high yielding variety of BARI developed vegetables seed of bottle gourd, okra, pumpkin and the seedlings of cabbage, cauliflower, tomato, chili and eggplant were collected from Bangladesh Agricultural Research Institute (BARI). Plant height, stem diameter, number of leaves per plant, fruit length, fruit breadth, fruit weight of different vegetables in rooftop garden were significantly affected due to different locations in Dhaka city. Among the locations, per hectare production of cabbage was highest in Mohammadpur (34.50 ton/ha), highest amount of cauliflower production (40.70 ton/ha) was observed in Adabor. On the other hand, in case of per hectare tomato production, highest amount of yield was recorded in Mohammadpur (95.17 ton/ha). Similarly, per hectare chilli production was highest in Kolabagan (6.80 ton/ha). Highest amount of eggplant production was found in Mohammadpur (13.82 ton/ha). In case of okra, highest fruit weight per hectare (13.89 ton) was observed in Mohammadpur. Similarly, in case of bottle gourd, the highest fruit weight per hectare (61.85 ton) was observed from Dhanmondi. Besides this, the highest amount of pumpkin production (24.61 ton/ha) was also found in Dhanmondi. From the study, it is revealed that different locations have the potentiality to influence the yield of vegetables in the Dhaka city context as well as to increase total production per unit area of rooftop garden.
