Harp-N-Tek Products
Harp-N-Tek™ Enhanced Fertilizer Blend 18-18-18 increased peanut yields by an average of almost 180 pounds per acre in replicated small plot trials.
It’s the exclusive Harpin Protein that makes Harp-N-Tek™ Enhanced Fertilizer blends supercharge the nutrient uptake in peanuts. Harpin Protein has been combined with a traditional balanced nutrient and micronutrient formulation, and the result is a new dimension in peanut crop performance.
Harp-N-Tek turns on the plant’s growth and stress-defense systems, which enhances the plant’s ability to absorb and translocate the nutrients made immediately available in the formulation. More nutrient uptake is better because it means more vigorous cellular activity, growth, fruiting, and stress tolerance.
Harp-N-Tek 18-18-18 is a dry, water soluble formulation available in 25 pound bags. Harp-N-Tek 18-18-18 is applied as foliar spray that is used as needed based on production goals and the crop’s needs. Used at bloom stage, Harp-N-Tek 18-18-18 improves uptake of nutrients and fruit set. The average peanut plant blooms around 600 times but only sets fruit 10% to 11% from those blooms, so this is a critical stage for a boost from Harp-N-Tek 18-18-18.
As a tank mix partner, Harp-N-Tek 18-18-18 is compatible with most crop protection products used on peanuts. It should be added to the tank first.
