Nano fertilizers are gaining much importance in agriculture as they are required only in lower quantity which will help farmers to reduce the cost incurred for cultivation and improve the crop output. An experiment was carried out during December 2020 to March 2021 to investigate the profitability in sesame cultivation due to soil application of organic nano NPK at Onattukara region in Kerala. Ten treatments were arranged in randomized block design and were replicated thrice. The treatments consisted of 2 levels of organic nano NPK (25 kg/ha and 50 kg/ha) with FYM and without FYM, combination of organic nano NPK (25 kg/ha and 50 kg/ha) and 50 per cent recommended dose of NPK with FYM and without FYM, soil test based recommendation of NPK and FYM along with absolute control. It was found that the soil application of organic nano NPK 50 kg/ha and FYM 5t/ha (T6) had significantly produced higher seed yield (712.5 kg/ha). Subsequently, higher gross returns (Rs. 2,13,750/-), net returns (Rs. 1,06,554/-) and BC ratio (1.99) for sesame was obtained for T6 treatment.
