Abstract: An experimental field trial was conducted during the Rabi season, 2020 in Crop Research Farm (CRF), Agronomy Department, Naini Agriculture Institute, SHUATS, Prayagraj, Uttar Pradesh, entitled “Effect of boron and zinc levels on growth and yield of yellow mustard (Brassica campestris L.)”. The trial was laid out in Randomized Block Design having nine treatments and three replications. Two factor i.e. boron and zinc having two levels, boron (1&2 kg/ha) and zinc (5&10 kg/ha) consisted along with RDF as NPK and S each at 80:40:40:40 kg/ha respectively. The results revealed that the maximum number of siliqua per plant (86.07), no. of seed per siliqua (40.27), test weight (3.85 g), seed yield (1.95 t/ha), stover yield (2.96) and harvest index (39.70%) was obtained in the treatment T2 (RDF + 1 kg B/ha). The maximum total cost of cultivation (27931.00 Rs/ha) obtained in the treatment T9 (RDF + 2 kg B/ha + 10 kg Z/ha). The maximum gross return (96560.00 Rs/ha) obtained in the treatment T2 (RDF + 1kg B/ha). The maximum net return (69739.00 Rs/ha) and B: C ratio (2.6) obtained in the treatment T2 (RDF + 1 kg B/ha) respectively.
