Growth performance and harvest index of sweet potato (Ipoma batatas, Lam) under integrated soil fertility management in Andosol and Nitisol soils

This dataset represent the raw data obtained following the cultivation of two sweet potato varieties (A white skin white-fleshed and a purple skin orange-fleshed) in two agroecological zones of Cameroon dominated by Andosol and Nitisol soils. The soil chemical composition plus that of the organic manures (Rice husk biochar, poultry litter, fast compost and Tithonia diversifolia leaf powder) is part of the data set. The growth parameters; primary  branch number, main stem length, petoile length, leaf area index, and harvest index components; adventitious roots, dry biomass, weight of small, medium and big roots, marketable and total yield were collected during the experimentation.
