Effects of Maize-Straw Biochar and NPK Fertiliser on Groundnut (Arachis Hypogaea L.) Yield and Soil Loss During Harvesting
Information on the effects of biochar on soil loss associated with groundnut harvesting remains limited. Hence, a 3 × 3 factorial field experiment arranged in a Randomised Complete Block Design (RCBD) with three replications, consisting of three rates of maize-straw biochar (0, 3 and 6 t ha⁻¹) and NPK 15:15:15 fertilis...
