A field experiment was conducted on medium black soil to study the evaluation of nano fertilizer in Bt. cotton (Gossypium hirsutum L.) under rainfed condition at Dry Farming Research Station, Junagadh Agricultural University, Targhadia, Gujarat, during kharif- 2017-18 to 2020-21. The experiment comprising of six treatments viz., T1. 80 kg N ha-1 through urea, T2. 1/10 (8 kg N ha-1) RDN through nano fertilizer, T3. 1/5 (16 kg N ha-1) RDN through nano fertilizer, T4. 1/2.5 (32 kg N ha-1) RDN through nano fertilizer, T5. Backbone polymer fragment liquid only as T2, T6. 80 kg N ha-1+ 10 tonne compost ha-1 + 500 kg castor cake ha-1 with four replications laid out in randomized block design. In pooled results, on growth and yield attributers viz., number of monopodia, sympodia and balls per plant and ball girth at maturity, root, stem, leaf, open ball growth rate and crop growth rate was found significant during all the four years, whereas partitioning percentage was found non-significant during all the four years. Similarly, seed cotton and stalk yield of Bt. cotton was found significant during all the four years. Maximum net realization (Rs. 109147 ha-1) was obtained under application of 80 kg N ha-1 through urea, followed by under application of 80 kg N ha-1 + 10 tonne compost ha-1 + 500 kg castor cake ha-1(Rs. 104025 ha-1) and 1/2.5 (32 kg N ha-1) RDN through nano fertilizer
