Commercial farmers in Chitwan are unaware of optimum spacing and fertilizer dose which limits the performance and yield of okra [Abelmoschus esculentus (L.) Moench]. An experiment was conducted to assess the response of okra to different levels of nitrogen 60, 90 and 120kg.ha-1 and 30×30, 45×30 and 60×30cm2 spacing under plastic mulched condition in Bharatpur-16, Chitwan from March to May 2018, using Ramdomized Complete Block Design (RCBD) with 3 replications. A hybrid variety of okra (Venus plus) mostly employed by farmers in Chitwan was used. Data were collected from ten randomly selected plants from the central rows in each plot and growth parameters were analyzed of various yield related parameters taken. The tallest plants were for 120kg.ha-1N and for the 30×30cm2 spacing. Pods from the interaction of 90kg.ha-1N for spaced at 45×30cm2 had the widest, the heaviest and the longest. Pods per plant were greatest for plants receiving 120kg.ha-1N spaced at 60×30cm2. Yield was best and cost:benefit (BC) ratio was most favorable for 90kg.Nha-1 treatment and for plants spaced at 45×30cm2. Overall data indicates that the nitrogen dose of 90kg.ha-1N with a spacing of 45× 30cm2 showed the most effective result statistically and economically.
