The effects of the application of a macronutrient foliar spray combined with micronutrients and growth regulators (Unifol) on peanut grown in a soil with high fertility were investigated. A control without fertilizer and a soil fertilization (250 kg/ha) with NPK 9-30-16 were also established. Other treatments were as follows: Unifol fertilizer (18-12 16) applied 23 days after germination: Unifol (18-12-6) applied at the beginning of flowering; Unifol (18-12-6) applied during flowering, and Unifol (18-12-6) applied 23 days after germination plus Unifol (7-23-7) at the beginning of flowering. No significant differences were found amongst treatments, but certain treatments showed higher productivity e given Unifol fertilizer (18-12-6) applied 23 days after germination plus Unifol (7-23-7) at the flower anthesis. In this treatment, the number of pods, weight of seeds and production of seeds were higher. Best production of forage occurred in the treatment receiving soil fertilization.
