Field experiments were carried out to study the effect of nanofertilzers on yield attributing characters and yield of okra (Abelmoschus esculentus L.) at the Agriculture Research Station, Binjhagiri, Chatabara, Institute of Agricultural Sciences, Siksha ‘O’ Anusandhan (Deemed to be University), Bhubaneswar, during February 2021-May 2021. The experiments were laid out in Randomized Block Design with three replications and fifteen treatments viz., Control (only FYM) T1,75% RDF (Conventional fertilizer in soil) T2, 100% RDF (Conventional fertilizer in soil) T3,75% RDF + IFFCO Nano Nitrogen (Foliar spray) @ 3 ml/l T4,75% RDF + IFFCO Nano Nitrogen (Foliar spray) @ 4 ml/l T5,75% RDF + IFFCO Nano Nitrogen (Foliar spray) @ 5 ml/l T6,100% RDF+ IFFCO Nano Nitrogen (Foliar spray) @ 3 ml/l T7,100% RDF+ IFFCO Nano Nitrogen (Foliar spray) @ 4 ml/l T8,100% RDF+ IFFCO Nano Nitrogen (Foliar spray) @ 5 ml/l T9,75% RDF+ Geolife N:P: K (19:19:19) @ 1 g/l T10,75% RDF+ Geolife N:P: K (19:19:19) @ 2 g/l T11,75% RDF+ Geolife N:P: K (19:19:19) @ 3 g/l T12,100% RDF+ Geolife N:P: K (19:19:19) @ 1 g/l T13,100% RDF+ Geolife N:P: K (19:19:19) @ 2 g/l T14, 100% RDF+ Geolife N:P: K (19:19:19) @ 3 g/l T15. The present study revealed that the maximum plant height (107.41 cm), was obtained with T3 +IFFCO Nano N(Foliar sprays @ 3 ml/litre), whereas maximum fruit length (14.26 cm) and maximum fruit weight(16g) was obtained with T3 + Geolife NPK(19:19:19) @2g/l. The maximum yield per plant (193.93 g) was recorded with T2 +IFFCO Nano N (Foliar sprays @ 4 ml/l).
