As manuring with compound fertilizers in large cocoa nurseries can be labour intensive two nursery trials were established in Sabah to evaluate the potential of using slow-release fertilizers (SRF) in reducing application frequency. As one-off application for short periods of nursery retention (3-4 months) all four SRF's i.e. Nurseryace Kokei Triabon and Fertimel gave cocoa growth equal to compound fertilizer. Over a longer retention period of six months only Fertimel at 1 tablet per bag continued to support good cocoa growth. As split (1 1) applications over a six month period Kokei Fertimel and Triabon were superior to Nurseryace and equal to 12 applications of compound fertilizer for most of the characters assessed. In addition Triabon consistently produced large stem girths ideal for early budgrafting and superior root-mass than the compound fertilizer treatment. Furthermore repeated application of compound fertilizers induced a moderately high incidence of zinc and iron deficiencies which was negligible in SRF plots

Abstract

As manuring with compound fertilizers in large cocoa nurseries can be labour intensive two nursery trials were established in Sabah to evaluate the potential of using slow-release fertilizers (SRF) in reducing application frequency. As one-off application for short periods of nursery retention (3-4 months) all four SRF's i.e. Nurseryace Kokei Triabon and Fertimel gave cocoa growth equal to compound fertilizer. Over a longer retention period of six months only Fertimel at 1 tablet per bag continued to support good cocoa growth. As split (1 1) applications over a six month period Kokei Fertimel and Triabon were superior to Nurseryace and equal to 12 applications of compound fertilizer for most of the characters assessed. In addition Triabon consistently produced large stem girths ideal for early budgrafting and superior root-mass than the compound fertilizer treatment. Furthermore repeated application of compound fertilizers induced a moderately high incidence of zinc and iron deficiencies which was negligible in SRF plots
