摘要

Bioproductivity of two contrasting watershed management system were evaluated in pot and field experiment to ascertain the effect of management and slope on the productivity of okra. The field studies were conducted on four slope gradients of watershed in an experiment arranged in a randomized complete block design (RCBD). The pot experiments were carried out on the soils of the two management practices (managed and unmanaged) and were arranged in a complete randomized design (CRD) with three replicates. NPK fertilizer 15∶15∶15 at the rate of 150kg/ha was applied as blanket treatment and okra used as test crop. The experiment was carried out on a sandy loam typic paleudult in Amawbia Anambra state southeast Nigerian. The data generated from the study were subjected to analysis of variance and significant mean differences were separated using least significant difference (LSD). The result of the study showed that natural environments of the four slopes in managed plots significantly increased the growth and yield parameters of okra than the unmanaged plots. Slope 4 (plain) of the managed watershed recorded statistically similar productivity with the unmanaged plots by virtue of their non-significant difference (P < 0.05) exhibited in most of the parameters assessed. The NPK fertilizer result indicated that the treatment boasted the productivity of both managed and unmanaged watershed ecosystem.
