A Pot culture experiment was carried out at Agriculture Research Institute, Rajendranagar, To study the impact of Nano Nitrogen in combination with zinc (soil application or foliar spray) on yield, in paddy crop. The soils employed in net house experiment were selected based on low, medium and high zinc availability classes obtained from the zinc analysis data of surveyed samples. They are low (0.4 mg kg-1), medium (0.71 mg kg-1) and high (1.30 mg kg-1). The results revealed that the highest dry matter at Panicle initiation, Grain and Straw yield were observed in the treatment applied with hundred percent recommended dose of nitrogen through NCU granules along with RDPK and soil application of 25 kg zinc sulphate ha-1 resulted in an increase in grain and straw yields by 23 & 24 % over basal application of 1/3rd of 100 % RDN through NCU granules along with RDPK coupled with Nano nitrogen sprays (each at MT & PI stages in rice) and soil application of 25 kg zinc sulphate ha-1
