間作栽培可提升耕地的利用率，並可有效控管作物的生長。本研究以不同玉米和大豆品種進行單間作，以瞭解不同品種間作對作物生長和產量之影響。試驗中發現，以甜玉米和黃豆間作時，可明顯促進甜玉米生長，平均單株穗重為325公克，相對於甜玉米單作，提升77.3%；糯玉米與黑豆間作下，糯玉米之單株平均穗重為323公克，與糯玉米單作相比提升35.4%，但以黃豆或黑豆與玉米間作，無論是在單株平均莢數或單株平均莢重，都與單作無顯著差異。顯示間作栽培對玉米產量有顯著增加的效果。綜合試驗結果可知，玉米與大豆間作時會因品種之差異而影響產量，其中以甜玉米和黃豆間作對玉米生長與產量效果最佳。

Intercropping can improve arable land utilization and effectively controls the crop growth. In this study, varietal effects on growth and yield of maize in maize-soybean intercropping system were investigated. Results revealed that intercrops between sweet maize and soybean significantly increased sweet maize yield, with ear weight of 325 g which was increased by 77.3% than that in single-cropping system. Similarly, intercropping between waxy maize and black soybean led to an ear weight of 323 g in waxy maize which was increased by 35.4% than that in single-cropping system. However, intercropping between soybean or black soybean and maize did not show a significant difference in pod number per plant and pod weight per pod of soybeans compared to single-cropping system. Our results showed that intercropping was advantageous for maize yield. In conclusion, the maize-soybean intercropping may have apparent impact on the grain yield of maize due to varietal difference. In particular, sweet maize-soybean intercropping can effectively increase growth and yield of sweet maize.
