Determining the Influence of Boron and Sulphur on Growth, Yield and Nutrient Uptake of Mustard (Brassica juncea L.)

A field experiment was carried out during the rabi season of 2021-22 at the Crop Research Farm, Department of Agronomy, Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj to study the response of Indian mustard [Brassica juncea (L)] to different levels of sulphur and boron. The experiment was comprised of 9 treatments with including all the combination of three sulphur levels (0, 10 and 20 kg/ha) and three levels of boron (0, 2 and 4 kg/ha). Results revealed that the highest plant height, plant dry weight (g/plant), crop growth rate (g/m2/day), relative growth rate (g/g/day), Number of siliqua per plant, Number of seed per siliqua, test weight (gm), Seed yield (q/ha), Stover yield (q/ha) were recorded with combination Boron (2 kg/ha) + Sulphur (20 kg/h) and application of (control) recorded maximum harvest index (%). Maximum gross return, net return and B:C ratio were also recorded with application of Boron 2 kg/ha + Sulphur 20 kg/ha.
