A study tested a weed-killing mixture on soybean plants to see how it affected weed growth and crop yield. Different doses of the mixture were compared to hand weeding and a weedy check. The highest dose of the mixture reduced weed growth the most, leading to better crop yield and profits compared to lower doses or hand weeding. The study found that using the right amount of the weed-killing mixture can help soybean plants grow better and produce more seeds.
