Department of Tropical Crop Science, Agricultural University Wageningen, The Netherlands aut Woody legumes as live support systems in yam cultivation [Elektronische Daten] II. The Yam -Gliricidia sepium association [Arnoud Budelman] This paper describes the effect of Gliricidia sepium, used as live support system on the development and tuber yield of Water Yam (Dioscorea alata). The leguminous perennial was planted in rows 3 m apart. The in-row distance between the trees was 1 m. In the alleys 2 rows of yam were planted, 1 m apart, with an in-row distance of 0.5 m. The aim of the experiment was to separate the effect of the leaf mulch produced by the trees, which was used to green-manure the yam crop, and the effect on the tuber yield that stems from the presence of the live stakes. Using Gliricidia sepium trees as live support more than doubles the yield per unit of area of yam; 8.8 ton ha−1 (yam sole-cropped, control) against 20.7 ton ha−1 (yam-tree association). Staking explains slightly more of the yield increment than the mulch factor. The trees and the mulch derived create more favourable conditions for development of the yam plant, while the capability of the trees to extract nutrients from soil layers that can not be reached by the yam roots is demonstrated. It is proposed to select and breed yam cultivars directly in relation to suitable live support systems. Such integrated tree-annual crop systems potentially provide substitutes for the practice of shifting cultivation.
