FRUITS LEAFY

The study reviewed the effects of poultry manure (PM) on the growth and yield of selected fruit and leafy vegetables in Nigeria. With the increasing need for sustainable and eco-friendly farming practices, poultry manure has become an important organic nutrient source due to its high content of nitrogen, phosphorus, potassium, and essential micronutrients. It enhances soil fertility, improves structure and water-holding capacity, and promotes beneficial microbial activity. Findings from several experimental trials across different agro-ecological zones in Nigeria revealed that poultry manure significantly improved vegetative growth and yield parameters such as plant height, leaf area, number of fruits, and total yield. The optimal application rate generally ranged between 10–30 t/ha, depending on crop type and soil condition. Studies also indicated that integrating poultry manure with inorganic fertilizers such as NPK 15:15:15 produced superior results in nutrient availability and crop performance. In conclusion poultry manure is a sustainable, cost-effective, and environmentally friendly soil amendment capable of improving vegetable productivity anmaintaining long-term soil health in Nigeria.
