The researchers studied how different levels of boron and sulphur affected the growth and yield of yellow mustard plants. They tested 9 treatments with varying amounts of these nutrients and found that the best combination for plant height and dry weight was 30 kg/ha of sulphur + 3 kg/ha of boron. For crop growth rate, 30 kg/ha of sulphur + 2 kg/ha of boron was most effective. The highest yields in terms of number of silique/plant, length of silique, test weight, number of seeds/silique, stover yield, and seed yield were achieved with 30 kg/ha of sulphur + 3 kg/ha of boron.
