The present experiment entitled “Effect of foliar application of nano urea on yield attributes and yield of wheat (Triticum durum Desf.) in Malwa region of Madhya Pradesh.” was conducted during rabi season in year 2022-23 at Rajmata Vijayaraje Scindia Krishi Vishwa Vidyalaya, College of Agriculture, Indore (M.P.). The experiment was laid out in RBD (Randomized Block Design) with 8 treatments and three replications. The treatment consists of T1 (Control (only P2O5 and K2O applied)), T2 (Recommended dose of fertilizers (120-60-40 kg/ha of N, P2O5 and K2O)), T3 (Recommended dose of N fertilizers (Basal 60 kg/ha N + 2-spray of 2% Urea rest N top-dressed) with P2O5 and K2O), T4 (Basal 60 kg/ha N with P and K + 2-spray of 4% NU), T5 (Only P2O5 and K2O applied as basal + 60 kg/ha N top dressed + 2- spray of 4% NU), T6 (2-spray of 4% NU with P2O5 and K2O), T7 (2-spray of 4% NU without P2O5 and K2O) and T8 (High organic N (Neem cake) with 2-spray of 4% NU (no P2O5 and K2O)). The results showed that the Recommended dose of N fertilizers (Basal 60 kg/ha N + 2-spray of 2% Urea rest N top-dressed) with P2O5 and K2O treatment (T3) performed the best in terms of number of effective tillers/plant, length of ear head (cm), test weight (g), grain yield (kg/ha), straw yield (kg/ha), biological yield (kg/ha) and harvest index (%). This was followed closely by the treatment involving sequential application of Recommended dose of fertilizers (120-60-40 kg/ha of N, P2O5 and K2O) (T2) and Basal 60 kg/ha N with P and K + 2-spray of 4% NU (T4). The Control (only P2O5 and K2O applied) treatment (T1) consistently gave the lowest values for all the parameters measured. Overall, the findings suggest potential benefits of foliar nano urea application on wheat productivity in the study region

Nano Urea, Foliar Application, Wheat, Yield Attributes, Recommended NPK Dose, Basal NPK Application, Top Dressing, Malwa Region, Madhya Pradesh

Based on the results, foliar application of nano urea was found to improve yield attributes of wheat. Treatment T3, which received the recommended dose of nitrogen fertilizer along with foliar sprays of nano urea, recorded the highest number of effective tillers, ear head length, test weight, grain yield, straw yield and biological yield. However, these parameters were also improved under T2 and T4 treatments involving recommended NPK dose and basal nitrogen with nano urea sprays, respectively. In contrast, the control treatment T1 showed the lowest values. Therefore, the study concluded that foliar application of nano urea has the potential to enhance wheat productivity and yields in the study region
