| Abstract | This study aimed to determine suitable Leucaena leucocephala cutting height and plant spacing for machine harvest under sandy saline soil for renewable energy to reduce field production cost. The experimental design was split-plot in Randomized Complete Block Design with 4 replications. The main plot was 3 levels of cutting height (5,10 and 15 cm. from the ground surface). The sub plot was 4 plant spacing ((50x50)x150, (75x75)x150, 50x200 and 100x200 cm.). The results showed that there was no difference in plant height among all treatment where the average plant height at 12 months was 344.46 cm. Furthermore the cutting height did not in fluent to dry matter yield of leucaena, while the (50x50)x150 cm. plant spacing promoted the highest (p<0.05) dry matter yield at 3,308.34 kg rai-1. Next, the leucaena wood from energy treatment had similar chloride (0.18%), ash content (1.78%) and heat value (17.93 MJ kg1) which pass the critical biomass fuel standard. Finally, the leucaena can be grown under saline soil with low cutting height and narrow double rows spacing for machine harvest. |
