PRODUCTION OF SWEET POTATO (Ipomoea batatas (L.) Lam) IN AGROFORESTRY SYSTEM: CASE STUDY OF AN EXPERIMENTAL UNIT IN SANTARÉM, PARÁ, BRAZIL

Abstract

Agroforestry systems (AFS) play a key role in recovering degraded areas and restoring fragmented landscapes, enabling the diversification of species that can be cultivated simultaneously. In this context, the introduction of short-cycle crops, such as sweet potato (Ipomoea batatas (L.) Lam), in agroforestry systems is a viable and affordable option for income generation due to low production costs and the relatively short cycle of this crop. A species of the Convolvulaceae family, sweet potatoes are recommended for hot climates. In this scenario, the present study aims to evaluate the production of sweet potatoes in different agroforestry arrangements. The experiment was conducted at the Experimental Farm of the Federal University of Western Pará in Santarém, State of Pará, Brazil. Sweet potato was cultivated in agroforestry systems in a completely randomized design, with three plots in each treatment (full sun, African mahogany reforestation, and teak reforestation). The results showed that, in the specific conditions of this study, sweet potato did not adapt to cultivation in shaded areas. The highest production was in full sun, where the consortium with forest species still does not provide shading for cultivation. These findings highlight the importance of considering the specific characteristics of sweet potato and its sunlight needs when planning and implementing agroforestry systems. Understanding these results contributes to making informed decisions regarding the development of cultivation and management strategies aiming to optimize sweet potato production in agroforestry systems.
