Boron is critical to peanut quality. While boron fertilization may only occasionally improve peanut yields, it almost always is necessary for the prevention of “hollow heart” and other concealed disorders that severely reduce crop value. Peanuts need a constant supply of boron during all stages of growth, but especially so from flowering to harvest. Fertilizing with boron will help peanuts: Improve root nodule development for more nitrogen fixation and protein production Produce and retain more flowers and pegs Enhance calcium utilization Move sugars and protein from leaves to nuts Prevent “hollow heart”
