Roselle, N, Pulpable biomassAbstract
A field experiment was conducted during 1995 and 1996 to study the effect of nitrogen levels on yield of pulpable biomass (stalk) of 4 varieties of roselle (Hibiscus sabdariffa L.). With the increased dose of nitrogen, stalk yield was increased. Nitro- gen up to 160 kglha was found proportionate to the yield and further addition of nitrogen showed no significant result. Higher biomass was recorded in HS 7910 (15.8 tonneslha). Pulp yield unbleached 50 to 53% and bleached 45 to 47% was found comparable to the traditional raw materials like bamboo and pine.References
