Purpose: Foeniculum vulgare (fennel) is one of the most important medicinal and aromatic plants well known for its essential oil and fruit value. The research on adding vermicompost and sheep manure to the soil is an important area of applied agricultural research in sustainable development. The objective of our study was to compare the fixed and […]
Purpose The study investigated the efects of poultry and goat manures on the kinetics of potassium fxation and release in some sandy loam and loamy soils of Ogun State, Nigeria. Methods The treatments consisted of poultry and goat manures applied at 25 g and 100 g/5 kg soil set in completely randomized design with three replicates. Potassium fxation […]
Purpose In soil-based nursery media, topsoil, poultry droppings and sawdust conventionally provide anchorage, nutrients and aeration, respectively. Considering poultry droppings’ scarcity and sawdust’s inertness nutrient-wise, more readily available organic wastes should be explored as substitutes. Here, we evaluated the effect of such substitution on media fertility, aimed at seeking alternatives to the conventional practice. Methods […]
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 […]
