This research evaluates the impact of vermicomposting using municipal solid waste (MSW) mixed with poultry litter (PL) or farmyard manure (FYM) on soil fertility and maize growth (Zea mays). At PMAS Arid Agriculture University in Rawalpindi, a greenhouse experiment was conducted using a completely randomized design (CRD). The treatments comprised combinations of municipal solid waste with poultry litter and farmyard manure, applied with and without half of the recommended NPK fertilizer rates. The study found that integrating vermicompost with lower NPK fertilization significantly improved soil characteristics. The organic matter content, the availability of nutrients, particularly nitrogen, phosphorus, and potassium, and the ability to distinguish between different amounts of micronutrients, including iron, zinc, copper, and manganese, were all improved. These soil improvements resulted in notable increases in maize growth metrics, such as plant height, root and shoot biomass, and overall yield. This study suggests a sustainable and efficient way to improve soil fertility and maize crop productivity by combining vermicompost with reduced NPK fertilizer rates, thus promoting integrated nutrient management techniques.
