Abstract: The number of leaves per plant increased with increase in poultry manure rate. Applications up poultry manure at all rates in the entire plots generated high weed yield that the control plots were significantly lower (p 0.05) than plots with poultry manure. Weeds were suppressed because the control plots were degraded and had low soil fertility. After the experiments, the plots with poultry manure were more fertile than the control plots. Thus, there were increases in soil N (0.84%), organic matter (3.93%) P (13.45ppm), while the exchangeable cations K (0.76), Ca (0.71) and Mg (0.63) Cmol (+) kg-1, respectively. The high organic matter percentage, with increase in the other soil chemical components, it is an indication that poultry manure has high potential of gradual nutrient release to the soil that can help to improve the fertility of a degraded soil; thereby sustaining yield under-continuous cropping system.
