Abstract: A field experiment was conducted on farmers field at Kautha, Tq. Kandhar, Dist. Nanded, Maharashtra during Kharif-2018 to find out the effect of foliar nutrition on leaf reddening of Bt (Gossypium spp.) cotton under rainfed condition. The experimental result indicated that among the various treatments application of 100 per cent RDF + foliar spray of DAP @ 1% + KNO₃ @ 1% + MgSO₄ @ 1% and micronutrient grade II @ 0.5% followed by 100% RDF + 19:19:19 @ 1%+ MgSO₄ @ 1% ₊ Micronutrient grade II @ 0.5% at critical growth stages helps in increase the leaf nutrient status, uptake of N, P, K, S, B, Fe, Mn, Zn, Cu and increases the yield of Bt cotton under rainfed condition.
