Abstract
An experiment was conducted at Kizibbani Research Station, Zanzibar, Tanzania to study the effects of various agronomic practices on the performance of water yam (Dioscorea alata). Staked plants on ridges, holes, and mounds spaced 1 m apart were applied with faryard manure (FYM) at (25 t/ha) or triple phosphate (46% P2 O5) at 50 kg/ha. Gliricidia stems were used for all staked treatments at one month after planting (MAP). Harvesting commenced at 11 MAP. There was signifiant difference (P = 0.05) among the treatment means.
All staked treatments yielded more than unstaked ones.
The highest yield (2.75 kg/ plant) was from staked/ridge/FYM treatment.
Lowest yield per plant (0.63 kg) was observed with the unstaked + mound + FYM treatment.
Highest percentage loss due to non staking was realized in mounds + FYM, while lowest percentage loss due to non staking was observed when yam was planted in holes without fertilizer application.
This work confirmed that staking is essential to maximise yield in yam.
FYM is also most suitable because of its residual effect and slow release of its nutrients.
