A study was conducted in India to see how different amounts of Sulphur, Zinc, and NPK fertilizer affected the growth of Yellow Mustard plants. They found that a combination of 45 kg Sulphur and 5.5 kg Zinc per hectare resulted in the tallest plants and the most branches. The plants also had the highest dry weight when treated with this combination. These results were significant at different stages of plant growth, showing that Sulphur and Zinc can positively impact the growth of Yellow Mustard plants. Further research is needed to confirm these findings in similar conditions.
