Abstract


This study aims was to analyze physiological responses, growth and production of corn based on agarwood agroforestry, and to analyze the effect of corn cultivation on the growth of agarwood stem diameter. This study used factorial experimental design, with 2 treatments and 3 replications, the first treatment was corn planting systems (monoculture and agroforestry), and corn varieties. This study uses two varieties of corn (local varieties and commercial varieties). Each treatment combination consisted of 24 plants, so that ± 288 maize plants were obtained. The results showed that there was a decrease in the growth of corn grown in monoculture and planted with gaharu. Maize grown in agarwood land showed stunted growth, indicated by the low value of plant height, number of leaves, and stem diameter and significantly different from plant height, number of leaves, and diameter of corn stems grown in monoculture. Tissue test results showed that the absorption values of N, P, K, Na, and Mg elements were not different, either corn in monoculture or corn fields planted in agarwood land.
