Organic Inputs on Maize (Zea mays) Yield and Chemical Properties of Two Ultisols

Effects of organic inputs (OIs) on maize grain yield and chemical properties Ultisols were assessed at Msekera Misamfu Agricultural Research Stations in the medium high rainfall regions respectively Zambia. The OIs included biomasses leguminous species Cajanus cajan, Tephrosia vogelii, Crotalaria juncea, in-situ composted native grasses shrubs called fundikila, modified fundikila using Mucuna pruriens, cattle manure, with fertilizer as a control. After two crop growing seasons, manure significantly increased soil pH, while levels matter. At Msekera, total N by 300%. Misamfu, Cajanas cajan 35%. did not increase available P K both sites. In first season had higher mean (6075±368 kg/ha) than (3567±715 kg/ha). Maize yields for second differ from those season. lower combined (5405±242 (7426±430 A 70% decline occurred plots compared to Leguminous generally performed better Misamfu. sites, traditional OIs, cow OIs. We concluded that effects vary climatic conditions these need be considered when selecting use farmers.
