Abstract: The experiment was conducted at the roof of third floor of Biotechnology department of Sher-e-Bangla Agricultural University, Dhaka during October, 2017 to March, 2018. The two factorial experiments were laid out in Completely Randomized Design (CRD) with three replications. Here, three levels of nitrogen dose N0: 0 kg N ha-1, N1: 100 kg N ha-1, N2: 130 kg N ha-1 and three levels of phosphorous dose P0: 0 kg P2O5 ha-1, P1: 50 kg P2O5 ha-1, P2: 80 kg P2O5 ha- 1 were used in this experiment. Growth and yield contributing parameters significantly influenced by different doses of nitrogen and phosphorus fertilizers. The dose of N2 treatment gave the highest plant height (87.45 cm) and most of the growth parameters increased with increasing nitrogen levels up to N2 treatment. The dose of P2 treatment gave the highest plant height (79.45 cm) and most of the growth parameters increased with increasing phosphorus levels up to P2 treatment. The treatment combination N2P2 gave the highest fruit diameter (4.26 cm), fruit length (11.91 cm), yield of fruits plant-1 (200 g), average fruit yield plot-1 (0.81 kg), individual fruit weight (0.84 g) and average fruit yield (6.79 ton/ha). Based on the findings, it can be suggested that the combined use of 130 kg N ha-1 with 80 kg P2O5 ha-1 increased plant growth and fruit yield of chili in rooftop garden. It is apparent that growth and yield of Capsicum annuum may be increased by using nitrogen and phosphorus fertilizer except loses through leaching or other factors.
