The present investigation was conducted to study the effect of nano fertilizer in the growth yield and quality of okra (Abelmoschus esculenthus). The experiment was carried out at the instructional farm of ICAR- Krishi Vigyan Kerndra, Pathanamthitta, Kerala, during the year 2021. The experiment was laid out in randomized block design with three replications. Ten different treatments were carried out with different combinations of fertilizers. The result obtained with treatment T2 (Soil application of 50% recommended dose of fertilizers as conventional fertilizer + 50% recommended dose of nano N as foliar application, nano P&K as soil application) was recorded the best among in all combination of conventional fertilizer NPK and nano NPK in term of growth, yield attribute and quality parameters like plant height 120.21 cm, number of leaves per plant 83.99, number of branches per plant 3.62, days to first harvesting 46.97, pod length 12.72cm, pod width 1.65cm, number of pods per plant 29.23, average of pod weight 12.67g, pod yield per plant 370.39g, pod yield per plot 8.89kg, pod yield 131.69q ha-1and TSS 2.930Brix. The highest cost benefit ratio 3.59 was also observed in T2 (Soil application of 50% RDF as conventional fertilizer + 50% recommended dose of nano N as foliar application, nano P&K as soil application).
