Abstract
This study assessed the impact of nitrogen (N) and boron (B) fertilization on yield, nutrient composition, and nutrient uptake in Indian mustard (Brassica juncea) in Chitrakoot, Madhya Pradesh, India. A field trial featuring 13 treatments combined reduced nitrogen levels, nano-urea applications, and different boron doses, using a randomized block design with three replications. Treatment T12 [½ recommended nitrogen dose (RDN) + two nano-urea sprays + 1.25 kg B ha⁻¹] achieved the highest seed yield (1523.81 kg ha⁻¹), surpassing the control (100% NPK as per RDF) which yielded 958.73 kg ha⁻¹. T12 also had the highest nutrient concentrations 2.78% nitrogen, 0.482% phosphorus, and 0.74% potassium as well as the highest nutrient uptake, with nitrogen at 42.36 kg ha⁻¹, phosphorus at 7.34 kg ha⁻¹, and potassium at 11.28 kg ha⁻¹. These results indicate that combining nano-urea with boron, especially at elevated boron levels, can significantly improve yield and nutrient absorption in mustard, highlighting its potential for sustainable farming in semi-arid areas.
