Effect of fertilizer on biochemical composition, and antioxidant properties of white‑fleshed sweet potato (Ipomoea batatas L.) flour

This study evaluated the impact of different fertilizer treatments on the proximate composition and antioxidant properties of flour from two white-fleshed sweet potato varieties (PCS and LCCS). The tubers were cultivated in the Sayo district of the Kellem Wollega Zone, Ethiopia. A two-factor experimental design with three blocks was employed, incorporating six treatments: eluate (T1), digestate (T2), compost (T3), a digestate-compost mixture (T4), a negative control (T-), and a positive control
