Abstract
A field experiment was conducted in year 2022 in Rabi season at Rajaula Agriculture farm, Mahatma Gandhi Chitrakoot Gramoday Vishwavidyalaya Chitrakoot, Satna (M.P.). Experiment was laid out in randomized block design with thirteen treatment combinations, varying levels of nano-urea and boron application, alongside a standard 100 % NPK as per RDF treatment as the control. Results showed significant differences in seed and oil yield across treatments. The highest seed yield of 1523.81 kg/ha was achieved with T12 (½ RDN + two nano-urea sprays + 1.25 kg B), a notable improvement over the control (T0) at 958.73 kg/ha. Oil content ranged from 13.1% to 35.6%, with the highest in T12, which also produced the maximum oil yield of 542.48 kg/ha. The lowest oil content (13.1%) and oil yield (190.47 kg/ha) were observed in T11 (½ RDN + one nano-urea spray + one water spray + 1.25 kg B). Treatments incorporating nano-urea and higher levels of boron showed the most pronounced increases in both oil content and yield, suggesting a synergistic effect of these nutrients on mustard productivity. Statistical analysis confirmed significant improvements in yield and oil quality with combined boron and nano-urea applications, indicating that T12 is the optimal treatment for maximizing mustard production under similar agro-climatic conditions.
