More pounds of seed per acre are needed for the larger-seeded cultivars. Your seed company representative or seed dealer can provide specific recommendations. If rows are 48 inches wide, a double row of beans can be planted. Optimum area per plant for most bush bean cultivars is approximately 36 square inches. Do not operate the planter faster than 3 miles per hour.
Faster speeds result in seed injury and uneven stands.
Cultivation Shallow cultivation is best. Cultivate only as needed to control grass and weeds. To minimize the spread of disease, do not cultivate when plants are wet. To control weeds, several good herbicides are available, including Basagran, Dacthal, Dual, Prowl, and Treflan. Irrigation Irrigation is required for successful commercial production.
