摘要

An experiment was conducted for three consecutive years to investigate the effect of poultry manure (PM) application on soil physical properties, performance parameters and nutrient uptake of cocoyam (Xanthosoma saggitifolium) in two locations in Southwest Nigeria. The treatments consisted of five tillage methods and five levels of poultry manure (0, 2.5, 5.0, 7.5 and 10 t ha 1) arranged as a factorial experiment using randomized complete block design (RCBD) with three replicates. Soil temperature and bulk density were reduced as application rate of PM increased from 0 to 10 t ha 1 ,while porosity and moisture content increased. Leaf N and P increased with rate of PM up to 10 t ha 1 and leaf K, Ca, Mg, cormel and corm yield increased up to 7.5 t ha 1. The r values between leaf N, P, K, Ca, Mg, cormel plus corm yield and PM were 1.00, 1.00, 0.62, 0.55, 0.61, 0.51, respectively. The PM significantly increased soil physical properties, nutrient uptake, growth and yield of cocoyam. It is recommended at application rate of 7.5 t ha 1 for optimum performance of cocoyam.
