Productivity of Arabica Coffee in Brawijaya University's Agroforestry

DOI: 10.22161/ijeab.92.15

Abstract:
Agroforestry is an agricultural system that combines annual crops with various woody or annual plants. The research carried out in arabica coffee agroforestry of Brawijaya University’s forest with pines as shading plant. Differences in management mechanisms result in differences in arabica coffee production and environmental conditions in the four pine-arabica coffee agroforestry management models in UB forests. The research’s purpose is to analyze production and biodiversity of arabica coffee in UB forests. Based on the results, it can be concluded that different levels of cultivation management have a significant influence on productive branches, number of unproductive branches, branch length, number of clusters each branch, and harvest yield. The average harvest yield BMP treatment was 3473.39 g each plant. The total diversity index value of understorey plants in UB Forest's coffee and pine agroforestry ranges from 1.4 – 2 (the diversity index values obtained for each plot from LC, MC, HC, and BMP management were (1.4), (1.52), (1.73), and (2.02)) with the value of H'= 1 – 3.322 (Shannon-Wiener diversity index). This result indicated that vegetation especially understorey diversity is classified as moderate.
