Abstract

The effects of different staking methods, using 0-5000 stakes ha-1, on the yield and economics of producing white Guinea yam were studied in an area with over 3000 mm annual rainfall. Staking increased tuber yield 34-105% over unstaked yam. Yield in plots with two stands to a stake was the highest. Tuber yield and size were positively correlated with stake population ha-1. Weeds were controlled better in plots with several stands to a stake. Staking cost varied with the staking method, the costliest being the use of synthetic rope in a net arrangement. Staking six stands to one stake gave the highest net cash return ha-1 which was 136% of that given by unstaked yams. The results are discussed in relation to their practical use in increasing the profitability of yam production.
