Title A name given to the resource RICE CULTIVATION IN AN EBBTIDE SYSTEM IN THE MARANHÃO LOWLANDS, SOUTHEASTERN PERIPHERY OF AMAZONIA A CULTURA DO ARROZ EM SISTEMA DE VAZANTE NA BAIXADA MARANHENSE, PERIFERIA DO SUDESTE DA AMAZÔNIA Creator An entity primarily responsible for making the resource Marcelino Silva Farias Filho, Altamiro Souza de Lima Ferraz Júnior Description An account of the resource  Agricultural production in the Maranhão State, southeastern periphery of Amazonia, Brazil, is predominantly smallholder-based and uses slash-and-burn technology. Nevertheless, other environmentally less aggressive land use systems are also relevant for food production, especially the so-called ebbtide system, in the Maranhão lowlands. This paper describes and evaluates ebbtide production, within the landless settlement project “Diamante Negro/Jutaí”, located in Monção and Igarapé do Meio, municipalities of the Maranhão lowlands. Our farmer-based assessment consisted of interviews with 14 farmers and in loco observations. Furthermore, an agroecological assessment was conducted, based on participative field experimentation, with 15 local farmers. The main factors causing rice productivity losses are related to hydric stress situations and rodents (Arvicola sapidus). The productivity and milling yield of improved rice varieties did not differ statistically. KEY-WORDS: Rice; Maranhão lowlands; smallholder agriculture; ebbtide production.    A produção agrícola do Maranhão advém, em grande parte, da agricultura familiar, no tradicional sistema de corte e queima. Entretanto, outros sistemas agrícolas menos agressivos ao ambiente figuram no Estado, como mantenedores da produção de alimentos. Dentre eles, a agricultura de vazante, desenvolvida na Baixada Maranhense, assume posição de destaque. A pesquisa caracterizou e avaliou esse sistema de produção. Foram realizadas observações de campo, nas diversas localidades pertencentes ao Assentamento Diamante Negro/Jutaí, cujo território abrange áreas dos municípios de Monção e Igarapé do Meio, na Baixada Maranhense. A avaliação do sistema, sob a ótica do agricultor, foi realizada com base na aplicação de questionários a 14 agricultores e observações in loco. A avaliação do sistema, do ponto de vista da Agroecologia, foi feita a partir de experimentação participativa, com quinze agricultores das comunidades analisadas. As principais perdas observadas na cultura do arroz estão relacionadas com o estresse hídrico das plantas e com o ataque de roedores (Arvicola sapidus). A produtividade e o rendimento de engenho dos genótipos inseridos não diferiram estatisticamente. PALAVRAS-CHAVE: Arroz; Maranhão; agricultura familiar; agricultura de vazante.
