Agroforestry system has been recently developed by the community to meet their needs. However, many people do not understand yet to select suitability plants on the agroforestry land. This research aims to determine the land suitability of agroforestry components in Pangli sub-district, Sesean District, Toraja Regency. This research carried out in the way comparing the requirement of plants and characteristic at land. Plants in research location were Robusta coffee, cocoa, banana, mangos-teen, Buangin (pine-mountain), sugar palm, Betung bamboo, and Elmerilla Ovalis. The result of the research indicated that the land suitability of plants was moderately suitable (S2) to marginal suitable (S3). Limitation factors that limit plant growth are predominantly rainfall and also temperature, but both of these limiting factors are difficult, and they cannot be repaired.

Agroforestry can become one of the solutions in the land management system to overcome problems arising from the land-use change. The study purposes were to know the technical form of agrisilviculture management system and to know the productivity of the agrisilviculture system. Data of agrisilviculture management systems were obtained from observation results, interviews, questionnaires, and literature study, which then being analyzed descriptively with a qualitative approach. This study was conducted in Timusu Village, Liliriaja District, in Soppeng Regency. In total, 15 farmers were selected as respondents. Data on the productivity of agriculture systems were obtained from interviews and vegetation surveys. The land area classified into three categories, such as the land area less than 0.6 Ha, 0.6 to 1 Ha, and more than 1 Ha. The data were analyzed quantitatively. The results showed that the agrisilviculture management system in Timusu Village consists of land preparation, seedling procurement, planting, maintenance, and harvesting. The average amount of agrisilviculture productivity in the land area classification of more than 1 Ha was equal to Rp 23.167.389/Ha/year, the land classification of 0.6 to 1 Ha was Rp15.333.366/Ha/year, and land area classification of less than 0.6 was Rp18.455.483/Ha/year

Changes in land use from forests into agricultural land raises many problems such as land to be limited so that people use agroforestry patterns as sources of income. This study aims to determine the pattern of agroforestry management and calculate the contribution of agroforestry to the total income of farmers. This research is located in Landi Kanusuang Village, Mapilli Polewali District, West Sulawesi. The method of data was done thought using purposive sampling on 30 respondents and making a plot sample size of 20mx50m as much as 10 plots. Data is processed and analyzed with descriptive and quantitative methods. The results showed that the composition of the type of agroforestry system consists of 8 types of plants with agroforestry system where the vertical structure of the agroforestry garden stands 3 strata. Strata A with a height of > 15 m, Strata B with a height of 5-15 m and strata C with a height of 1-5 m. In addition, the average income was Rp. 18,831,743.743/year with agroforestry contribution to the total income of farmers of 76.14%.
