Abstract: A field experiment was conducted at Demo field, Krishi Vigyan Kendra, Theni during 2018 to evaluate the impact of organic and inorganic sources of fertilization on growth and yield of okra (Abelmoschus esculentus L. Moench). Brinjal variety CO 3 was used as a test variety during the study. The experiment was conducted in a randomized block design with eight treatments replicated thrice. The treatment details are as follows,T1 - 100% NPK, T2 - 125% NPK, T3 - 75% NPK + FYM + PSB, T4 - 75% NPK + FYM + Azotobactor, T5 - 75% NPK + FYM + Azotobactor + PSB, T6 - 50% NPK + FYM + PSB, T7 - 50% NPK + FYM + Azotobactor, T8 - 50% NPK + FYM + Azotobactor + PSB. Nitrogen was applied at the rate of 125%, 100%, 75% and 50% kg/ha as per recommended dose of fertilizer. As per the treatment, remaining nitrogen was supplied through FYM (FYM = As per treatment, PSB = Azotobactor = 2 kg/ha). The biometric observation viz., growth attributes like plant height (cm), number of leaves per plant, number of branches per plant, number of flowers per plant and yield attributes like pod length, number of pods per plant, pod weight (g), yield (kg ha-1) were recorded. Among the different treatment application of 75% NPK + FYM + Azotobactor + PSB (T5) produced significantly higher plant height (30.95cm), number of leaves per plant (18.73), number of branches per plant (7.09), number of flowers per plant (11.1) and pod length (cm), number of pods per plant (10.75), pod weight (g), yield of 750 kg ha-1compared to other treatments. Over all, from the experimental results, it could considered that application of 75% NPK + FYM + Azotobactor + PSB as a better option for achieving higher productivity and profitability of Bhendi.
