The present study was carried out to evaluate the effect of nitrogen on growth and yield of chili (Capsicum annuum L.) under rooftop conditions. The single factorial experiments were laid out in Randomized Complete Block Design (RCBD) with three replications. Four levels of nitrogen N0: 0 kg N ha-1, N1: 90 kg N ha-1, N2: 110 kg N ha-1 and N3: 130 kg N ha-1 were used in this experiment. Growth and yield contributing parameters significantly influenced by different doses of nitrogenous fertilizers. The dose of N2 gave the highest plant height (80.97 cm) and most of the morphological parameters increased with increasing nitrogen levels up to N2. The treatment N3 gave the highest fruit length (4.93 cm), yield of fruits plant-1 (165.33 gm), average fruit yield plot-1 (0.66 kg), individual fruit weight (1.97 g) and average fruit yield (5.533 kgha-1). Based on the present results, it can be suggested that use of 130 kg N ha-1 increased plant growth and fruit yield of chili in rooftop garden.
