African mahoganies can be an alternative for wood production in agroforestry systems and/or mixed-species plantations. In this study, we aimed to evaluate the growth, yield and stem form of Khaya grandifoliola C. DC. and Khaya ivorensis A. Chev. established in successional agroforestry systems and in mixed plantations of both species. A randomized block experiment was set up with the following treatments: (T1) mixed plantation of African mahoganies with elimination of regenerating community by herbicide application; (T2) mixed plantation of African mahoganies with selective management of regenerating community; (T3) agroforestry system including African mahoganies with elimination of regenerating community, through mowing operations (non-selective); and (T4) agroforestry system including African mahoganies with selective management of regenerating community. The results shown a higher growth rate of both Khaya species in T1, especially in relation to T2, possibly due to the more effective herbicide control of the dominant invasive species. The structural complexity, diversity and pruning regime of the regenerating plants in the T4 treatment possibly caused positive benefits in the Khaya trees growth. It is possible that Khaya trees captured part of the fertilizer intended for the food crops, although this effect is more pronounced for K. ivorensis. The stemwood volume stocks in T1 and T4 treatments were similar for both species. The total mean annual increments of volume at 58 months were: 3.3 m3 ha−1 year−1, 1.3 m3 ha−1 year−1, 2.2 m3 ha−1 year−1, and 2.8 m3 ha−1 year−1, for the T1 to T4, respectively. K. grandifoliola had higher height and DBH growth rates than K. ivorensis. However, K. ivorensis trees produced straighter stems, with desirable use to sawmilling MenosAfrican mahoganies can be an alternative for wood production in agroforestry systems and/or mixed-species plantations.
