Effect of sulphur, zinc and boron on growth and yield of mustard

Abstract

A field experiment was conducted during Rabi season of 2023-24 at Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences to determine “Effect of Sulphur, Zinc and Boron on growth and yield of Mustard”. The treatments consisted of three levels of Sulphur (15, 30 and 45 kg/ha), Zinc (5 kg/ha) and Boron (2 kg/ha) along with recommended doses of fertilizer and a control (80-40-40 kg N-P-K/ha). The results revealed that the significantly higher plant height (213.46 cm), higher plant dry weight (40.77 g), maximum number of siliqua/plant (213.8), maximum number of seeds/siliqua (17.73), higher test weight (5.78 g), higher seed yield (2.15 t/ha), and higher stover yield (6.03 t/ha) were recorded with treatment 9 (Sulphur 45 kg/ha + Zinc 5 kg/ha + Boron 2 kg/ha). The maximum gross return (183754.25 INR/ha), net return (129235.00 INR/ha) and B:C ratio (2.37) were also recorded with application of Sulphur 45 kg/ha + Zinc 5 kg/ha + Boron 2 kg/ha (treatment 9) was found to be productive as well as economically feasible.
