550 In the spring at planting, broadcast recommended phosphate and potash fertilizer and 30 to 40 lbs nitrogen per acre and work into the soil. Broadcast the balance of nitrogen in two separate applications, one-half 90 days after planting and the remaining half 30 days later. Total nitrogen rate following a legume is 135 lbs nitrogen per acre.
551 This is a boron sensitive crop. Apply 1 lb boron per acre with the last nitrogen application. (Recommendation when soil test boron is less than 3.1 lbs per acre)
