  1. Means of the LAIs, dry aboveground biomass and extinction coefficient with the same letter are not significantly different at 5 % (p > 0.05) level based on Duncan multiple comparisons of means. The LAIs reported were taken 86 and 49 DAP in 2013 and 2013/2014 seasons respectively while the dry aboveground biomass were taken 84 DAP in the two seasons. The extinction coefficients reported are means from replicates
