The nutrient contents of a widely-consumed leafy vegetable produce – Telfairia occidentalis - using
poultry manure (PM) and mineral fertilizer (Nitrogen, phosphorus and potassium-NPK) application were
evaluated for comparison. PM at four levels (0, 5, 10 and 15 tonnes) and a standard rate of 90kg NPK per
hectare was applied. Leaves were harvested for immediate analyses at 15 weeks after planting to determine
the proximate composition, elemental nutrient composition, water-soluble vitamins and anti-nutrient contents.
Kinetics of vitamin degradation during drying of leaves at 50, 55 and 60oC and durations for 30 to 180 minutes
was investigated. Data obtained showed that proximate composition was significantly affected by treatments
