The present study entitled, “Impact of Integrated Nano and Non-nano urea on Nitrogen Efficiency and uptake in grain and straw in late sown wheat” was conducted at Samargopalpur farm of CCSHAU Regional Research station, Rohtak during the Rabi season of 2022-23 and 2023-24 The experiment was laid out in randomized block design with eight different treatment combination of integrated use of nano and non-nano urea on late sown wheat (DAS) replicated thrice. Based on the research investigation it was found that application of nano and non-nano urea. Results revealed that the treatment involving 50% recommended dose of nitrogen (RDN) through urea + 2 sprays of nano urea (T₆) exhibited superior NUE indices like agronomic efficiency and partial factor productivity. This implies that nano urea can integrated with conventional urea for improving nutrient uptake

The integrated use of nano and non-nano urea has been found to be significant in terms of nitrogen use efficiency and nitrogen uptake in grain and straw. The 100 % RDN through Urea + 2 foliar sprays of Nano Urea at 30 DAS and 50 DAS have significantly improved the available status of N, P and K. while in case of various nitrogen use efficiencies, the partial factor productivity and nitrogen harvest index was obtained with 50 % RDN through Urea +1 foliar spray of Nano Urea at 30 DAS. On the other hand, the 50 % RDN through Urea +2 foliar sprays of Nano Urea at 30 DAS and 50 DAS resulted into maximum agronomic efficiency under late sown wheat conditions
