Farm Yard Manure (FYM) is a traditional and widely used organic fertilizer and soil conditioner in agriculture. It is composed of decomposed organic materials derived from farmyard waste, such as animal dung, plant residues, and other organic matter found on farms. The process of creating FYM involves collecting, piling, and allowing these organic materials to undergo natural decomposition over a period of time. This breakdown is facilitated by microorganisms like bacteria, fungi, and earthworms. This research primarily focus on improving the uniformity of manure distribution, enhancing operational efficiency, and ensuring environmental sustainability. The spreader was constructed using durable materials, including a mild steel frame and a stainless steel hopper with a 5 kg capacity. Key performance indicators such as spreading width, uniformity, operational efficiency, and labor savings were measured. The results indicated that the spreader significantly outperformed traditional methods and basic mechanized spreaders in terms of efficiency and uniformity of manure application. The use spinning disc ensured consistent discharge rates and reduced the risk of blockages. Factors affecting the discharge rate, such as manure characteristics (moisture content, particle size, and consistency), spreader design (hopper shape, discharge mechanism, and opening size), operational parameters (spreader and beater speed, hydraulic pressure), field conditions (terrain and soil type), and environmental factors (temperature and weather), were analyzed in detail. The study highlighted the importance of regular maintenance and calibration in achieving optimal performance. The economic analysis demonstrated that the investment in this advanced manure spreader is justified by increased crop yields and reduced labor costs. Additionally, the environmental impact assessment showed improved nutrient management and reduced emissions, contributing to sustainable agricultural practices. The developed farmyard manure spreader offers a robust solution for efficient and uniform manure application, addressing the needs of modern farming practices.
