Abstract

On farm trials were conducted to compare dry matter yields and nutrient uptake of selected tropical cover crops and biochar application on different Samoan inceptisols. Consequent improvements in corm yield of two cultivars Samoa 1 and Samoa 2 were determined. Plant analyses showed that the N and P contents of erythrina was grossly higher than mucuna cover. Yet, Mucuna pruriens resulted in the highest nutrient buildup over the six month fallow period. Yield data suggests that mucuna with low rates of complete fertilisers can help maintain optimum taro yields under the shortened fallow durations. However, it appears that the yield responses of the taro crop to fallow treatments are site-specific.
