A study was done to see how well sunflowers and pigeonpeas grow together in a field. They found that planting sunflowers and pigeonpeas in certain row patterns can make them grow better and produce more. The best way to plant them together is in a 3:1 row proportion. This method gave the highest yield of sunflowers and pigeonpeas, as well as the most profit. Intercropping sunflowers and pigeonpeas in this way can be a good way for farmers to make more money from their land.
