Growth of guanandi and cassava and arrowroot production in agroforestry systems
Journal Title: Revista Verde de Agroecologia e Desenvolvimento Sustentável - Year 2019, Vol 14, Issue 2
Abstract
In the Paraíba do Sul Valley, between the states of Rio de Janeiro and São Paulo, the replacement of the Atlantic Forest for coffee cultivation has degraded soils and watercourses. Growing forest species can help restore this environment. The guanandi (Calophyllum brasiliense Cambess.) is a native forest species with great potential for economic exploitation of wood. Its cultivation in agroforestry system - AFS can become more advantageous due to its moderate growth. The objectives of this research were to compare the growth of guanandi in monoculture and agroforestry diversification in simple and biodiverse AFSs, as well as to evaluate the performance of cassava (Manihot esculenta Crantz.) and arrowroot (Maranta arundinacea L.) in these systems, in cycles with high rainfall and water scarcity. The biodiverse AFS was added with pigeon pea, banana, juçara palm and arboreal diversity. Agroforestry systems did not affect the growth of guanandi, which increased the circumference of chest height in simple AFS after three years of conversion. Cassava and arrowroot food crops presented performance compatible with the planting density used in AFSs, with significantly higher yields in simple AFS. Arrowroot has withstood environmental stress on both AFSs and does not require replanting, naturally occupying the understory. Simple AFS is a system for farmers interested in obtaining the maximum yield of annual crops in association with the forest species. The biodiverse AFS is appropriate to diversify agricultural production and restore the environment concomitantly.
