- Intervention effect Poultry manure alone increased vine length, branching, shoot dry matter and fresh shoot biomass versus NPK alone or no fertilizer.
- Intervention effect Combined poultry manure and NPK produced the highest storage root yield and carotenoid content.
- Intervention effect A manure and fertilizer mixture significantly reduced storage root decay.
- Intervention effect No vine cutting increased fresh shoot biomass relative to cutting at 16 or 17 WAP.
- Intervention effect No vine cutting reduced carotenoid content relative to cutting at 16 or 17 WAP.
- Intervention effect Cutting date had no effect on storage root yield.
- Observation White fleshed TIS 87/0087 had higher fresh shoot biomass and storage root yield than orange fleshed Umuspo 3.
- Observation Orange fleshed Umuspo 3 had higher carotenoid content than white fleshed TIS 87/0087.
