Purpose Passion fruit cultivation and utilization is fast emerging in Nigeria. Poultry farms are increasing with the corresponding increase in poultry manure production which is relatively affordable by farmers. Two experiments were conducted to evaluate the effect of placement method and time of poultry manure (PM) application on early growth and dry matter partitioning of […]
Purpose The main objective of the study was to evaluate the application of different doses of onion residue compost as mixtures with bovine manure as organic fertilizers for a round tomato crop planted in the field. Method The data were obtained experimentally in pilot fields. The experimental design was completely randomized, with 4 m2 plots […]
Purpose The deterioration of agricultural soil can be alleviated by maintaining an appropriate level of soil organic matter by using organic amendments such as compost and biochar. The aim of this study was to investigate the effects of olive waste-based compost, wood-based biochar and their combination on the chemical and microbial properties of loamy clay […]
Purpose Fish waste is a protein-rich source that can be used as a value-added product in the formulation of organic liquid fertilizers. This study carried out to investigate the utilizing potential of fruit wastes of Ananas comosus and Carica papaya that contain bromelain and papain as major proteases in order to hydrolyze fish waste proteins to […]
Purpose This study was carried out to assess the effect of integrating microbiological fortification with vermicomposting process on biofertilizing quality of vermicompost as well as improvement of the availability of nitrogen and phosphorus in the product. Method A mixture of cow dung and vegetable market waste (1:1) was used for vermicomposting with Eisenia foetida as […]
Purpose To evaluate the development of beans (Phaseolus vulgaris L.), variety of BRS Pontal, in protected environment, irrigated with different irrigation levels due to crop evapotranspiration (ETc) and concentrations of treated domestic wastewater. Method The experiment was carried out in a protected environment using an experimental design arranged in randomized blocks with a 3 x […]
Purpose Using the effective approaches for modifying the recycled wood as a novel bulky agent improves the quality of soil amendment. This study aimed to compare the stability and maturity of the soil amendments produced by the compostation of forest industrial waste and sewage sludge on seed germination. Method Three materials, namely sawdust, sewage sludge, […]
Purpose Compost production technology and use are known among Ghanaians farmers. However, the long composting period averaging three months has had adverse effect on adoption. The black soldier fly (Hermetia illucens) larvae (BSFL) feed voraciously and breaks down organic wastes fast. Addition of rice husk biochar (RHB) neutralises acidity and aerates the compost. Combined application […]
