Simultaneous cultivation of agricultural and forest species may result in changes in plant community interactions, generating microclimatic changes within the understory and then modifying growth and yield characteristics of the intercropping systems. Thus, this study aimed to assess the radiation use efficiency, growth and yield of bean and soybean cultivated in succession under two arrangements of agroforestry and full sun. To these ends, two field experiments were conducted in Southern Brazil: bean in‐season and soybean off‐season. Absolute and relative growth rates, net assimilation rate, leaf weight ratio, leaf area ratio, specific leaf area, radiation use efficiency and yield of bean and soybean were assessed. The solar radiation flux was modified by plant arrangement and tree canopy characteristics. Shading affected growth and yield characteristics and the radiation use efficiency of the studied crops. From the results obtained in this study, it is possible to recommend crop bean cultivation in agroforestry systems. However, for soybean, due to the reduced yields obtained in agroforestry systems, further research should be conducted in order to study more spaced arrangements and crop insertion in the early years of agroforestry, in order to enable its insertion in agroforestry systems in Southern Brazil.

阳光充足和农林业系统中的豆-大豆演替：对辐射利用效率，生长和产量的影响

同时种植农业和森林物种可能会导致植物群落相互作用的变化，在林下产生微气候变化，然后改变间作系统的生长和产量特征。因此，本研究旨在评估在农林业和全日照两种安排下连续种植的豆类和大豆的辐射利用效率，生长和产量。为此，在巴西南部进行了两个田间试验：四季豆和淡季大豆。评价了绝对和相对生长率，净同化率，叶重比，叶面积比，比叶面积，辐射利用效率以及豆类和大豆的产量。太阳辐射通量通过植物布置和树冠特性进行了修改。遮荫影响了研究作物的生长和产量特性以及辐射利用效率。从这项研究中获得的结果，有可能推荐在农林业系统中种植豆类作物。但是，对于大豆而言，由于农林业系统中的单产下降，应进行进一步的研究，以便在农林业的早期研究更多的行距安排和农作物的插入，以便使其能够在巴西南部的农林业系统中插入。
