Two high-fibre sugarcane varieties adapted for energy use in Guadeloupe
In Guadeloupe (French West Indies), studies (REBECCA project) were conducted to investigate the benefit of producing sugarcane as a dedicated energy feedstock using the entire dry shoot biomass (DSB).After a first selection from among 36 Poaceae, 10 sugarcane varieties were tested and compared to R579, the best local commercial sugarcane (CSC), (three replications, 40-m2 plots, volcanic soil) over 3 years in wet tropical conditions. Wet and dry biomasses as well as energy yield (EY, MJ/m2) were measured on stalks, tops, green and dead leaves. Two varieties (W181456, W179460) from WICSBS (Barbados) were very efficient and well-adapted. The DSB was 81 t/ ha/year and the low heating value of this DSB was 133 MJ/m2 after a 12-month cropping cycle. Dry/wet DSB was 0.36 (0.43 without tops). These varieties were cropped using the same practices as local CSC, but yields were higher: +33% for stalks and +71% for DSB). These two varieties could be considered as good feedstock for a biomass power plant but they need to be dried before being used. Growers, purchasers and agronomists are now informed of local potential yield and quality of the tested varieties.
