The study looked at when to plant and how densely to plant Ejiangdou No.8 beans to get the most yield. They tested three planting times and densities and found that planting in mid-April gives the best results. The ideal density for these beans is having 3700 hills per 667 square meters, which gives a yield of 2098.87 kilograms. So, if you want the most beans, plant them in April and space them out just right.
