STUDY ON PERFORMANCE OF SELECTED VEGETABLES CULTIVATED ON ROOFTOP AND FARM CONDITIONS

Abstract

Our agricultural land is decreasing day by day. In modern days rooftop farming can provide solution to mitigate this problem. We can use our roof of building to cultivate crops and increase food demand. This experiment was conducted at the roof of third floor of Biotechnology Department and Agroforestry farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the period from October 2017 to March 2018 to study on performance of selected vegetables (cabbage, cauliflower and broccoli) cultivated on rooftop and farm conditions. Data on plant height, number of leaf, leaf length, leaf breadth, head height, diameter and weight of cabbage, cauliflower and broccoli were collected. The field and roof top experiment were conducted in RCBD design with three replications. MSTAT-C computer package was used for processing and analysis of data. The mean differences were adjusted by Least Significance Difference (LSD) test at 5% level of significance. In cabbage, cauliflower and broccoli, yield parameters value were increased with increasing days after planting .In cabbage cultivation, plant height, leaf number, leaf length, leaf breadth, head height, head diameter and head weight were 36.65 cm, 12.52 cm, 22.69 cm, 21.29 cm, 18.39 cm, 54.81 cm and 939.72 g respectively at 60 DAT but in farm condition it were 27.66 cm, 9.84 cm, 18.31 cm, 17.44 cm, 16.24 cm, 50.74 cm and 865.61 g respectively at 60 DAT. In cauliflower cultivation, plant height, leaf number, leaf length, leaf breadth, head height, head diameter and head weight were 43.19 cm, 12.32 cm, 32.21 cm, 22.31 cm, 18.04 cm, 54.85 cm and 888.85 g at 60 DAT but in farm condition it were 38.64 cm, 9.96 cm, 26.43 cm, 18.21 cm, 16.15 cm, 50.26 cm and 740.43 gat 60 DAT. In broccoli cultivation, plant height, leaf number, leaf length, leaf breadth, head height, head diameter and head weight were 42.98 cm, 10.44 cm, 29.67 cm, 21.69 cm, 17.60 cm, 51.85 cm and 816.48 g at 60 DAT but in farm condition they were 34.12 cm, 8.43 cm, 22.46 cm, 19.47 cm, 16.28 cm, 47.54 cm and 574.13 g. For all species plant height, leaf number, leaf length, leaf breadth, head height, head diameter and head weight were recorded in roof top condition. Also, the highest curd length, curd diameter and yield was produced by cabbage followed by cauliflower and broccoli produced in roof top condition. The yield components and yield of cabbage, cauliflower and broccoli were highest in rooftop and lowest in farm.
