Title A name given to the resource Produtividade de raízes de mandioca consorciada com milho e caupi em sistema orgânico Yield of cassava roots intercropped with corn and cowpea in an organic system Creator An entity primarily responsible for making the resource Raul de Lucena Duarte Ribeiro, Dejair Lopes de Almeida, Antonio Carlos Pries Devide, Teresa Losada Valle, Cristina Maria de Castro, José Carlos Feltran Description An account of the resource Foram avaliados sistemas orgânicos de produção de mandioca 'de mesa', em Seropédica (RJ). O experimento constou dos seguintes tratamentos: monocultivo de mandioca (cv. IAC 576-70) e consórcios com milho experimental (cv. Eldorado), caupi (cv. Mauá) e milho+caupi. O manejo orgânico foi padronizado e toda a área experimental irrigada durante o período de permanência do milho no sistema. Do milho, foram colhidas espigas verdes (imaturas) e a parte aérea acamada na superfície do solo. O caupi foi incluído como adubo verde e cortado na floração, sendo mantidos os resíduos na superfície do solo. Ambos os consortes ocuparam as entrelinhas da mandioca, de modo alternado, semeados após a primeira capina da cultura principal. A cultivar IAC 576-70 mostrou-se adaptada ao manejo orgânico, com produtividade de raízes de padrão comercial próxima a 31 Mg ha-1. Não houve diferenças significativas entre o monocultivo e os três tipos de consórcios testados. A inclusão do milho representou potencial de renda adicional ao produtor, colhendo-se, em média, 18.125 espigas ha-1, o que correspondeu a 5,1 Mg ha-1. Os resíduos provenientes da roçada do caupi proporcionaram um aporte de biomassa fresca de 12 Mg ha-1, com uma expressiva contribuição em nitrogênio (cerca de 44 kg de N ha-1). A fabácea (leguminosa) cobriu por completo as entrelinhas da mandioca, demonstrando seu potencial de controle à erosão e a ervas espontâneas. O consórcio triplo mostrou-se vantajoso tendo em vista que a receita obtida com a venda do milho verde justificaria os custos da irrigação, além dos benefícios da inclusão do caupi e da não interferência dos consortes na produtividade da mandioca.Organic systems were evaluated for cassava root production directed to human comsumption in natura, at Seropédica-RJ. Treatments consisted of: cassava ('IAC 576-70') in single cropping and its intercropping with corn ('Eldorado'), cowpea ('Mauá') or corn plus cowpea. The organic management was standardized and the experimental area was submitted to artificial irrigation during the period of stay of maize in the system. 'Green' (immature) corn ears were harvested at the 'point' required for fresh marketing and the shoot placed on the ground. The cowpea was included to function as green manure being cut at flowering with residues left on the soil surface. Corn and cowpea were sown between cassava rows, in an alternate design, following the first weeding of the main crop (cassava). The cultivar IAC 576-70 showed suitability with respect to organic management, yielding approximatelu 31 Mg ha-1 of marketable roots. No significant differences were detected between cassava single cropping and any of the intercropping tested systems. Thus, corn crop has considerable potential for additional income to the growers. Yield of 'Eldorado' corn averaged 18.125 ears ha-1 correspponding to 5,1 Mg ha-1. Residues coming from cowpea cutting brought about an input close to 12 Mg ha-1, which meant an expressive contribution in nutrient elements, especially nitrogen (about 44 kg N ha-1). The legume crop, in addition, completely covered cassava inter-rows demonstrating its potential for controlling erosion and weeds. The triple intercropping becomes advantageous considering that corn harvesting would justify irrigation and that inclusion of cowpea meant benefitial effects to the system and did not interfere on cassava yield.
