Recently, many alternative fuels have been developed from plant residues containing cellulose and lignin. This study aims to determine the important role of eco-enzyme and mycorrhiza in increasing the growth rate of sugar cane and sacha inchi on marginal land. Both of these types of plants are broadleaf plants with high ligine content so they have the potential to produce biofuels and are tolerant to be cultivated on marginal lands. The application eco-enzyme on inceptisols increased the vegetative growth of plants at 10 and 20 HST, and the number of leaves at 30 and 40 HST. Giving mycorrhizae at a dose of 40 g/plant can increase the absorption of some macro nutrients so that it can increase the growth of plant length, number of leaves, root fresh weight, root dry weight and root length of Sacha inchi plants on Inceptisol soil which is classified as marginal land. There was an interaction between the administration of 22.5 ml/l ecoenzyme and 40 g mycorrhiza which affected the number of leaves and root length of sacha inchi 40 HST. The application of eco-enzymes and mycorrhiza to sugarcane nurseries with the bud-chip system accelerated the growth of sugarcane bud-chips, while in untreated inceptisol soils the growth was very slow. At the beginning of growth there was no difference in the growth rate of the seedlings, but plant height at 4 WAP was the highest growth rate when mycorrhizal  7.5 g/plant applied (data not published). Eco-enzymes contain microorganisms that help the process of decomposition, transport of nutrients, and mycorrhizae as biofertilizers that can provide nutrients for plants. Both of these materials do very well in increasing crop yields and marginal land productivity.
