ABSTRACT:

A pot experiment was carried out at the Greenhouse, Faculty of Agriculture complex, Kogi State University, Anyigba to investigate the effect of poultry droppings (100g, 200g, 300g,400g and control) on the growth of Amaranthus on a contaminated soil. A completely randomized block design (RCBD) with five treatments (four rates of poultry manure and control) was replicated four times. Treatment means were separated using Least Significant Difference (LSD) where necessary. Poultry manure had a significant influence on growth parameters such as number of leaves, stem girth, height and leaf area of amaranth. The poultry manure increased the level of nutrient concentration and heavy metals in the soil, but had no positive influence on the number of heavy metals found in the amaranth (biomass), as the heavy metals increased with increase in the rates of poultry manure. The application of 200g of organic manure (poultry droppings) gave the optimum result on the growth of Amaranthus on a contaminated soil.
