A field experiment was conducted to evaluate the effect of foliar application of nano urea applied in different concentrations and at different growth stages on yield and yield components of wheat (Triticum aestivum L) cv. “Phule Samadhan” under normal field (EC < 2 dSm-1) and saline-sodic field ((EC >4 dSm-1) over two seasons viz., Rabi, 2021 and Rabi, 2022 at Post Graduate Institute Research Farm, Department of Soil Science and Agricultural Chemistry, Mahatma Phule Krishi Vidyapeeth, Rahuri. The experiment was laid out in randomized block design with eight treatments and three replications for wheat crop. The results revealed that among the different treatments, application of 75% N through urea (soil application) + 25% N through two foliar sprays of nano urea first 40 % at 30 DAS (tillering) and second 60% at 60 DAS (flowering) was found beneficial for increase in total uptake of nitrogen, grain and straw yield of rabi wheat however; treatment consisting application of General Recommended Dose of Fertilizers (120:60:40 kg ha-1 N:P2 O5 :K2 O
