Abstract: Corchorus olitorus and Celosia argentina are popularly consumed as vegetables in southwestern Nigeria because of their economic and nutritional importance. Therefore, pot experiments were conducted to compare the effect of poultry manure, cow dung, NPK 20:10:10 and urea fertilizers on growth, nutrients content and yield of Corchorus olitorus and Celosia argentina in Lagos southwest Nigeria. The recommended rates of NPK (400 kg ha^-1), urea fertilizers (200 kg ha^-1) and; poultry manure (10 t ha^-1) and cow dung (10 t ha^-1) were used as treatments. There was a control without any treatment. The two experiments were separately conducted in year 2010. The treatments were mixed with washed and air dried river sand. Compared with control, all the treatments significantly (p<0.05) increased plant height, number of leaves and dry matter yields of Corchorus olitorus and Celosia argentina. The Corchorus fertilized with NPK had the highest moisture content; poultry manure had the highest nutrient uptake while urea had the highest dry matter yields. Celosia argentina fertilized with poultry manure and cow dung recorded the highest moisture content, nutrient uptake while urea had the highest dry matter yields. The over all yield increase in relation to number of leaves of Corchorus olitorus are in order of NPK> poultry manure>cowdung>urea>control while increases in the leaves of Celosia argentina are in the order of poultry manure>NPK>cow dung>urea>control. Poultry manure, cow dung and NPK fertilizer serve as sources of nutrients for Corchorus and Celosia argentina. Poultry manure where available is better for the production of Corchorus olitorus and Celosia argentina.
