Resumo: | We aimed with this study to help maximizing cassava production for subsistence in indigenous communities at the Brazilian Pantanal, by introducing minimal changes to the usual indigenous way of cultivation aiming to reduce human labor in weed management in this crop. For that, we tested distinct intercrops and phosphate sources, taking the Babassu Indigenous Village, located in Miranda‑MS, Brazil, as a reference. The experiment involved the intercrop of cassava with pigeon pea (Cajanus cajan), jack‑bean (Canavalia ensiformis) and millet (Pennisetum americanum) and the source of phosphate fertilizer (mycorrhizal inoculants, P2O5 and without fertilization / mycorrhizal inoculum). Soil samples were collected to study the soil seed bank of spontaneous species. We adopted the phytosociological method to assess the absolute level of infestation, its composition density, frequency, dominance and importance value, and diversity coefficients of Simpson and Shannon-Weiner, as well as the Shannon Evenness Proportion (a sustainability coefficient) for all treatments. Areas were also grouped by similarity of plant species. Cultivation of cassava for subsistence in indigenous areas also selects certain spontaneous species, and management should focus in removing mostly by hand those established in the crop row; the damage to the crop may be higher in years of high abiotic stresses. There is no effect of phosphate supply source (P) in the level or composition of spontaneous species. There is clear evidence that the continued cultivation of cassava for subsistence in indigenous areas of the Brazilian Pantanal is sustainable over time, mainly when intercropped with other food species. |

Probamos consorcios de cultivos y fuentes de fosfato, teniendo como referencia la Aldea Indígena Babaçu, ubicada en Miranda-MS, Brasil. El experimento involucró al consorcio de yuca con gandul (Cajanus cajan), frijol de cerdo (Canavalia ensiformis) y mijo (Pennisetum americanum) y fuente de fertilizante fosfatado (inoculantes micorrízicos, P2O5 y sin fertilización / inóculo micorrízico). Se recolectaron muestras de suelo para estudiar el banco de semillas. Adoptamos el método fitosociológico para evaluar el nivel absoluto de infestación, su densidad de composición, frecuencia, dominancia e valor de importancia y los coeficientes de diversidad de Simpson y Shannon-Weiner, así como el índice de uniformidad de Shannon (un coeficiente de sostenibilidad). Las áreas también se agruparon por similitud de especies. El cultivo de yuca para subsistencia en áreas indígenas también selecciona ciertas especies espontáneas, y el manejo debe enfocarse en remover principalmente a mano aquellas establecidas en la línea de cultivo; el daño a los cultivos puede ser mayor en años de alto estrés abiótico. No hay efecto de la fuente de suministro de fosfato (P) sobre el nivel o la composición de las especies espontáneas. Existe una clara evidencia de que el cultivo continuo de yuca para la subsistencia en las áreas indígenas del Pantanal brasileño es sostenible en el tiempo, especialmente cuando se intercalan con otras especies alimentarias.Objetivamos maximizar a produção de mandioca para subsistência em comunidades indígenas do Pantanal Brasileiro, e verificar sua sustentabilidade ecológica, introduzindo mudanças mínimas no modo de cultivo indígena usual. Para tanto, testamos consórcios de cultivos e fontes de fosfato, tendo como referência a Aldeia Indígena Babaçu, localizada em Miranda-MS, Brasil. O experimento envolveu o consórcio de mandioca com feijão-guandú (Cajanus cajan), feijão-de-porco (Canavalia ensiformis) e milheto (Pennisetum americanum) e fonte de fertilizante fosfatado (inoculantes micorrízicos, P2O5 e sem fertilização / inóculo micorrízico). Amostras de solo foram coletadas para estudar o banco de sementes do solo de espécies espontâneas. Adotamos o método fitossociológico para avaliar o nível absoluto de infestação, sua composição densidade, frequência, dominância e valor de importância, e coeficientes de diversidade de Simpson e Shannon-Weiner, bem como a proporção de uniformidade de Shannon (um coeficiente de sustentabilidade) para todos os tratamentos. As áreas também foram agrupadas por similaridade de espécies. O cultivo de mandioca para subsistência em áreas indígenas também seleciona certas espécies espontâneas, e o manejo deve se concentrar em remover principalmente à mão aquelas estabelecidas na linha de cultivo; os danos à cultura podem ser maiores em anos de alto estresse abiótico. Não há efeito da fonte de suprimento de fosfato (P) no nível ou composição das espécies espontâneas. Há evidências claras de que o cultivo continuado de mandioca para subsistência em áreas indígenas do Pantanal brasileiro é sustentável ao longo do tempo, principalmente quando consorciado com outras espécies alimentares.Research, Society and Development2021-01-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1207010.33448/rsd-v10i1.12070Research, Society and Development; Vol. 10 No. 1; e56010112070Research, Society and Development; Vol. 10 Núm. 1; e56010112070Research, Society and Development; v. 10 n. 1; e560101120702525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/12070/10864Copyright (c) 2021 Germani Concenco; Michely Tomazi; Rodolpho Freire Marques; Sudeep Chandra; Vaishali Chandola; Thais Stradioto Melo; Laryssa Barbosa Xavier da Silvahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessConcenco, GermaniTomazi, MichelyMarques, Rodolpho Freire Chandra, SudeepChandola, VaishaliMelo, Thais Stradioto Silva, Laryssa Barbosa Xavier da 2021-02-20T21:19:23Zoai:ojs.pkp.sfu.ca:article/12070Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:33:44.808912Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
