Purpose This study aimed to achieve successful composting and aeration rate and to optimize the carbon:nitrogen (C:N) ratio to provide favourable conditions for the process. In the current experiment, investigation were made on variations in physico–chemical properties, i.e., temperature, ammonia and carbon dioxide emissions, pH, electrical conductivity (EC), organic matter (OM) and seed germination index […]
Purpose This experiment was initiated to evaluate the efect of flter cake and bagasse ash on the productivity of wheat under greenhouse conditions. Methods Six levels of flter cake and bagasse ash each separately and control check were arranged in a completely randomized design with three replications. Results At 100 tons/ha, both inputs resulted in the […]
Purpose In the present study, efect of earthworm-processed MSW was seen on biochemical, physiological, and yield responses of Abelmoschus esculentus L. Methods Plants were grown on diferent amendment ratios of municipal solid waste vermicompost (MSWVC). Pot experiments were conducted by mixing MSWVC at 0, 20, 40, 60, 80, and 100% ratios to the agricultural soil. […]
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 Waste management is one of the significant challenges facing Nigeria’s agricultural sector. To manage this problem, the conversion of agricultural wastes to biochar is a practical solution.Methods In this work, the chemical composition of biochar from rice husk and sugarcane bagasse, two predominant agricultural wastes, commonly generated in Nigeria was studied. These wastes were […]
Purpose Wheat straw is an agricultural waste which can be used as a cost effective animal feed. However, high hemicellulose and phytic acid content in wheat straw prevents it as a primary feed choice. Utilization of wheat straw in solid-state fermentation may result in wheat straw valorization and enzyme production. In this study, phytase production […]
Purpose Diferent agricultural substrates were evaluated for growth and productivity of cucumber under pot culture for kitchen gardening. Methods Several agricultural substrates such as leaf compost, compost, perlite, and coconut compost were used in with silt in several combinations. Seeds were sown in plastic pots of 9-L capacity and flled with growing substrates in various […]
Purpose Stevia rebaudiana residues composting is studied and optimized using a central composite experimental design Methods The influence of controllable composting variables [moisture (40–70%), aeration (0.05–0.30 Lair min−1 kg−1), and time (0–50 days)] on the temperature history and the properties of the compost (pH, organic matter) produced to determine suitable composting conditions. Mass balance and emitted […]
Purpose In this study, vermicomposted tannery wastes were applied in the organic cultivation of sweet pepper in a greenhouse. The effects of this organic matter addition on plant development and on the distributions of Cr(III) and Cr(VI) in plant tissues and organs were assessed. Methods In a greenhouse, organic sweet peppers were cultivated adding vermicomposted […]
Purpose This study aimed to investigate the efect of time interval between sowing and amendment with non-digested and digested poultry manure and their combinations with urea on the germination of three wheat cultivars (Slambo, Acsad, and Karim) in the desert soil. Methods The cultivars were sown on four diferent dates, i.e. directly, 10, 20 and […]
