Abstract
The effectiveness of newly developed organic and organomineral fertilizer (OMF) in improving nutrient availability soil physicochemical properties and performance of maize (Zea mays), pepper (Capsicum annum) and amaranthus (Amaranthus cruentus) was studied in experiments carried out at Akure in rainforest zone of Nigeria. Soils at sites of experiment were low in organic matter, N and P. Application methods of OMF were also studied in relation to performance of amaranthus. OMF, organic and NPK fertilizer (NPK) at 300 kg/ha increased soil and plant N, P, k, Ca, Mg and yield of maize, pepper and amaranthus. The 3.0 t/ha OMF gave highest maize cob and grain weight, whereas NPK gave highest number of pepper fruits. Increase in maize grain weight given by NPK and 3.0 t/ha OMF were 130% and 390% respectively. Increase in number of pepper fruits given by OMF, organic and NPK were 56%, 50% and 91% respectively. Fresh matter and leaf yield of amaranthus were increased by OMF applied by spot, ring and broadcast methods. Broadcast gave highest values of yield parameters, soil and plant nutrients content and highest soil moisture content.
