Ipil-ipil {Leucaena leucocephala (Lam.) de Wit} is considered as an
outstanding tree because of its worldwide success as a highly nutritious forage
tree. Thisstudy is an attempt to determine suitable spacing formaximumbiomass
production. Widerspacing (60 cm x 60 cm) provided maximum seedling growth
(height 177.9 cm and collar dia. 15.3 mm) and biomass production (green weight
276.0 g/seedlingand dry weight 166.5 g/seedling) at the age ofnine months of the
seedlings. However, closerspacing (15 cm x 15 cm) produced significantly higher
biomass(greenweight 28.21 ton/ha and dry weight 11.68 ton/ha) on an area basis.
Small land holding farmers may rear their livestock by planting this legume and
harvesting under a ‘cut-and-carry’ system which will supply high quality forage
that uses to supplement low quality roughage such as crop residues.
