Conversion of forest land into monoculture maize farming is one of the causes of reduced carbon storage, whereas planting forest land through maize agroforestry has the potential to increase carbon storage. The objective of the study was to measure and compare the biomass value and carbon storage of several strains of corn planted in agroforestry patterns with corn planted in monoculture patterns. This study used a randomized block design with two experimental blocks and each repeated three times. Sampling of maize was done by purposive sampling by taking six best strains based on vegetative parameters from 20 strains tested in the field. Measurement of maize carbon storage value was conducted using a slightly modified loss on ignition method. The results showed that maize biomass ranged from 0.80-4.69 tons/ha in the agroforestry block and ranged from 2.09-6.54 tons/ha in the monoculture block. The highest biomass value was found in the SC4 strain in the agroforestry block, while in the monoculture block it was found in the DC52 strain. The highest percentage of carbon was found in the panicle. The highest carbon storage was found in the seeds in the agroforestry block and stems in the monoculture block. The highest total carbon storage of maize in agroforestry block was found in SC4 strain at 2.48 tons/ha and DC52 strain at 3.18 tons/ha in monoculture block. The total carbon storage of trees and SC4 maize in the agroforestry block was 27.14 tons/ha. The biomass and carbon storage values of maize grown in agroforestry blocks were lower than those of maize monoculture blocks, but became higher when combined with the biomass and carbon storage values of trees.
