Abstract: Okra is one of the most important crops in Madhya Pradesh States. Okra production and yield maximization has not been attained due to lack of appropriate production practices such as optimum plant spacing and fertilizer use. Therefore, the research was conducted to assess the effect of sources of nitrogen and plant population, on growth and yield components of Okra (Abelmoschus esculentus (L). Moench). The treatments were factorial combinations of Six sources of nitrogen (Control, 100% N through urea (150:75:75 NPK/ha), 100% N through vermicompost, 100% N through FYM, 50% N through urea + 50% N through vermicompost and 50% N through urea + 50% N through FYM) four spacings (40 x 30 cm, 50 x 30 cm, 60 × 30 cm and 80 × 30 cm). The experiment was laid out in randomized block design factorial arrangement with three replications. Results indicated that, sources of nitrogen and plant population had significance influence on growth and yield components of okra. Maximum number of branches (2.93), number of leaves (15.95) and pod length (29.01 cm) was obtained from the interaction of sources of nitrogen through 50% N through urea + 50% N through vermicompost and 40 cm × 30 cm spacing. The highest fresh pod yield (46.14 t ha-1) and above ground biomass yield (119.34 t ha-1) was obtained from sources of nitrogen through 50% N through urea + 50% N through vermicompost and 60 cm × 30 cm spacing.
