The aim of this present investigation is to study the effect of foliar application of nano N and Zn on nutrient content and nutrient uptake by mustard (Brassica juncea L.) crop. The field experiment was carried out during October to March 2022 season at Instructional Farm, Rajasthan College of Agriculture, MPUAT, Udaipur which lies in agro-climatic zone IV-A of Rajasthan, India. The field was designed in a randomized block design having 10 treatments which were replicated thrice. The treatments include the various combination RDF and nano fertilizers of N and Zn. The application treatment T₆ (100% NPK Zn +1^st spray of Nano N and Zn at 30 DAS +2^nd spray of Nano N and Zn at 45 DAS) has significantly increased the nutrient content and nutrient uptake by mustard crop.
