INFLUENCE OF ORGANIC AND INORGANIC NUTRIENT SOURCES ON THE PROXIMATE COMPOSITION OF SELECTED MALVACEAE VEGETABLES

Abstract

The experiment was carried out at Obafemi Awolowo University Teaching and Research farm located at longitude 4'33^o E and latitude 7'28° N, 224 meters above sea level, laid out in a split block design with three replicates including the organic, inorganic (NPK 20:10:10) and control plot. Crude fibre (5.92%) and Ether (3.79%) content of the organic fertilizer were significantly different from the NPK 20:10:10 (5.27%; 4.17%) and control (4.53%; 3.97%). NPK 20:10:10 significantly influenced Ether content (4.17%) when compared to organic fertilizer (3.79%) and control (3.97%). The influence of the nutrient sources differs for each vegetable, ranging from the crude fibre, crude protein and ether content, which were the nutritional quality parameters assessed.
