Abstract

Poor quality and low productivity of ginger rhizomes made the product uncompetitive on the extra-regional market. This study tested the components that could produce rhizomes of similar quality to the Hawaiian grade. Three field experiments were carried out to evaluate fertilizer formulations, fertilizer rates with organic manures and system of cultivation, and system of cultivation and plant density. Organic manure increased overall yield by 25% and exportable grade ginger by 500%. Closer intra-row spacing produced higher yields in both systems of cultivation. Furrow cultivation maximized total rhizome yield and exportable grade ginger with a 50% reduction in fertilizer requirement of 500 kg. ha '). Furrow cultivation improved the exportable grade yield of ginger but not overall yield. The addition of phosphate to the 15-08-24 NPK did not improve yields. A combined technology of 25 cm intra row spacing, organic manure, furrow cultivation and NPK fertilizer (15-08-24) at 500 kg. ha'1 was compared to the existing technology on 2000 m2 plots. Exportable grade ginger increased by 300%, and cost of production fell from EC $1.31 kg to EC $0.57kg"' (US $1.00 = EC $2.70).
