The study conducted for two consecutive summer seasons in 2019 and 2020 at the Gemmeiza Agricultural Research Station, Gharbia Governorate, Egypt, investigated the effects of soil enhancers such as compost, agricultural sulfur, potassium humate, and spray whey on tiger nut on plant growth and production. The experiment included eight treatments: control, foliar spray of whey, compost applied alone and in combination with foliar spray for whey, agricultural sulfur applied alone and in combination with foliar spray for whey, and potassium humate applied alone and in combination with foliar spray for whey. The results showed that soil amendments and foliar sprays of whey significantly improved plant characteristics, with T4 and T6 being the most effective. The interaction between potassium and whey spray significantly increased plant parameters, such as shoot dry weight, nutrient uptake, yield, and tuber quality. Treatment T7 recorded the highest values for moisture, fat, and total titratable acidity, followed by compost alone.Therefore, it is suggested that tiger nut plants could be cultivated as a source for protein, oil, and milk while simultaneously incorporating soil enhancers and whey protein as an organic foliar spray for the cultivation of organic crops.
