A study was done to see how adding different amounts of sulphur and boron to sunflower plants affects their growth and yield. They tested two levels of sulphur and two ways of applying boron on sunflowers. The results showed that sunflowers treated with 50 kg/ha of sulphur and 0.2% boron spray had the tallest plants, the most leaves, and the biggest stem girth. These plants also produced the most seeds, had the highest test weight, and yielded the most seeds per hectare. Overall, this treatment gave the best economic returns compared to the other treatments.
