Cultivating a biodiverse ecosystem through the intercropping of corn and beans in an agroforestry system (AS) can be a strategy for sustainable and weather-resilient production. However, the reduction in solar radiation availability may pose a challenge to the success of this agricultural practice. The objective of this study was to determine the potential effects of solar radiation transmittance in an AS on the growth and production of corn and beans in both sole-crop and intercropped conditions. We conducted experiments using a randomized complete block design in a three-factorial arrangement (2 × 6 × 2) for corn and a two-factorial arrangement (2 × 5) for beans. The treatments included different cultivation environments (AS and full sun), corn cultivars (BRS 015FB, BRS 019TL), and plant arrangements. The plant arrangements involved both corn and bean cultivars (BRS Paisano) in monoculture and intercropped configurations with one and two rows of each species interspersed (1:1; 2:2). We assessed plant growth, yield, and biological efficiency indices for the crops. The results indicate that AS, with its reduced solar radiation, promotes greater plant height and leaf area in both corn and bean plants but results in lower productivity compared to full sun. Among the corn cultivars, BRS 019TL exhibited the highest productivity. However, in years with severe droughts, the use of intercropping with BRS 015FB shows greater land use efficiency within the AS. Furthermore, corn can be successfully intercropped with beans without a loss in production, while beans are best cultivated as a monoculture.

通过在农林复合系统（AS）中间作玉米和豆类来培育生物多样性生态系统可以成为可持续和耐候生产的一项战略。然而，太阳辐射可用性的减少可能会对这种农业实践的成功构成挑战。本研究的目的是确定 AS 中太阳辐射透射率对单作和间作条件下玉米和豆类生长和生产的潜在影响。我们使用随机完全区组设计进行实验，玉米采用三因子排列 (2 × 6 × 2)，豆类采用二因子排列 (2 × 5)。处理包括不同的栽培环境（AS 和全日照）、玉米品种（BRS 015FB、BRS 019TL）和植物布置。植物布局涉及玉米和豆类品种（BRS Paisano）的单一栽培和间作配置，每个品种散布一排和两排（1:1；2:2）。我们评估了作物的植物生长、产量和生物效率指数。结果表明，由于减少了太阳辐射，AS 可以提高玉米和豆类植物的株高和叶面积，但与全日照相比，其生产力较低。在玉米品种中，BRS 019TL 的生产力最高。然而，在严重干旱的年份，使用 BRS 015FB 间作在 AS 内显示出更高的土地利用效率。此外，玉米可以成功地与豆类间作，而不会造成产量损失，而豆类最好作为单一作物种植。
