Growth and Yield Performance of Chili (Capsicum annuum L.) on Rooftop of Different Height of Buildings

Abstract

In urban agriculture, rooftop gardening is a remarkable part which is practiced to overcome the food crisis and climate change; if it is not economically viable on the basis of productivity, then rooftop garden will not enhance and sustain. So, a pot experiment was conducted during November 2021 to April 2022 on the rooftop of different height of buildings and Agroforestry research field at Sher-e-Bangla Agricultural University, Dhaka-1207 to study the productivity of chili (BARI Morich 3). The experiment was laid out in a Completely Randomized Design with four replications. The treatments of this experiment were T1= Control (Ground, 0.0 m), T2= Rooftop of three storied building (11.28 m), T3 = Rooftop of six storied building (21.34 m) and T4 = Rooftop of ten storied building (34.75 m). Results indicated that soil moisture content, plant height, stem diameter, number of (leaf, branch and fruit), fresh and dry weight of plant, single fruit (weight, length and diameter), fresh and dry weight of yield per plant were significantly decreased with the increased of building height (T1>T2>T3>T4) and air temperature, soil temperature and light intensity were significantly increased with the increased of building height (T4> T3> T2> T1). As gradually increased the height of building rooftop, sequentially decreased the growth, yield and yield contributing characteristics of chili plant. Although ground performed the best productivity, up to rooftop of three storied building can be selected as an appropriate height for chili (BARI Morich-3) cultivation to increase the rooftop gardening.
