An experiment was conducted during rabi 2020-21 at the SVPUA&T, Meerut, Uttar Pradesh, to study the Effect of foliar application of nano and non-nano fertilizers on growth and nutrient use efficiency of Indian mustard [Brassica juncea (L.) Czern & Coss]. The investigation was carried out in randomized block design with three replications and 12 treatments of nutrient management practices viz., Control, N-P-K & S (120-40-40 & 20 kg/ha), 100% NPK & S + Zn 5 kg/ha, 100% NPK & S + Bio-stimulants, 100% NPK & S + Nano Zn, 75% NPK & S + NPK Consortia seed treatment, 75% NPK & S + Nano N, 75% NPK & S + Nano N + Nano Zn, 75% NPK & S + NPK Consortia seed treatment + Nano Zn, 75% NPKS + NPK (18:18:18), 75% NPKS + NPK (18:18:18) + Bio-stimulants and 75% NPK & S + Zn 5 kg/ha + Bio-stimulants + Nano N + Nano Zn. The highest growth parameter viz., plant height (216.16 cm), dry matter accumulation (102.7 g/plant) were recorded with treatment 100% NPK & S + Nano Zn whereas, the highest nutrient use efficiency was recorded with treatment 75% NPK & S + Zn 5 kg/ha + Bio-stimulants + Nano N + Nano Zn.
