Field experiment was carried out at the Teaching and Research Farm of Kwara State University, Malete, Ilorin, to evaluate the effect of compost, organomineral, and inorganic fertilizers on the growth and yield of Amaranthus caudatus as well as its residual effects. Amaranthus was grown with compost Grade B (unamended compost), organomineral fertilizer Grade A (compost amended with mineral fertilizer), and NPK 15-15-15 and no fertilizer (control). All the treatments except control were applied at the rate of 100 kg N/ha. The results indicated that the Amaranthus yield of 18.9 t/ha produced from Grade A was significantly () higher than 17.6 t/ha obtained from NPK fertilizer. Residual effect of Amaranthus growth parameters such as plant height, number of leaves, and yield values obtained from Grade A was also significantly () higher than that of NPK, compost, and control values. Thus, organomineral fertilizer could be used in cultivation of Amaranthus caudatus in Ilorin and in similar type of soil in similar agroecology.
