Results revealed that the total amount of available biomass from the system ranged from 8.76 to 10.50 t/ha/year. The highest amount of biomass for recycling was recorded from 2/3rd level of fertilizer dose (10.50 t/ha/year) under model I and the compost produced ranged from 5.4 to 8.4 t/ha/year and the highest was under 2/3rd level of fertilizer dose. The amount of nutrient contribution by recycling the compost in the garden ranged from 41.36 to 54.94 kg N, 32.69 to 42.55 kg P2O5 and 66.25 to 85.38 kg K2O per ha per year. The results also indicated that there was increasein the yield of main and component crops over the years. Yield of arecanut, citrus and pepper were higher at 2/3rd recommended level of fertilizer coupled with organic biomass recycling in the form of compost. However, banana yield was higher at full dose of recommended fertilizer.enarecanutbiomasscompostHDMSCSrecyclingyieldArticle
