A pot culture experiment was designed to develop a humic acid enriched liquid foliar nutrient formulation from thermochemical digestate obtained from food waste to increase the cumulative yield of amaranthus. Hoagland nutrient solution at strengths 0%, 25%, 50%, 75 % and 100 % combined with KOH(2 M) humic acid extract obtained from thermochemical digestate at 0% 1%, 2% and 3% strengths were applied to transplanted amaranthus once in weekly intervals. The results showed that spraying 50 % Hoagland solution enriched with 2 % humic acid extract derived from rapid thermochemical digestate of food waste was superior in terms of cumulative yield, leaf to shoot ratio, plant height, leaf width and leaf length. Even though foliar application of 75% strength of Hoagland nutrient solution with 2% strength of humic acid and 100 % Hoagland nutrient solution with 2 % humic produced a slight increase in yield and yield attributes, the increase was insignificant when compared to foliar application of 50 % Hoagland nutrient solution combined with 2 % humic acid. It is concluded that the foliar application of 50 % strength of Hoagland nutrient solution enriched with 2% humic acid extract obtained from rapid thermochemical digestate will increase the yield, leaf to shoot ratio and overall productivity of amaranthus.
