O entrave para a expansão dessa cultura pelos pequenos produtores é a impossibilidade de utilizá-la para alimentação, por isso, a importância de estudos que aliem o consorcio desta espécie com alimentícias, garantindo segurança alimentar e melhoria da renda. Com objetivo de avaliar a produtividade e a contribuição dos racemos na produção de mamona foram desenvolvidos dois experimentos, na Fazenda Lavoura Seca da Universidade Federal do Ceará, Quixadá-CE, 2011. Os experimentos consistiram nos consórcios entre plantas de mamona cv. BRS Energia com feijão caupi cv. Setentão e o com milho BRS 206. Foram avaliadas a produção e participação dos racemos primário, secundário e terciário como também a produtividade total em bagas e em grãos. Os dados de produtividade foram submetidos à análise de variância e as médias comparadas pelo teste de Tukey (p &lt; 0,05). Nos consórcios de mamona com feijão caupi e com milho, os racemos secundário e primário tiveram as maiores participações na produção, respectivamente. O feijão caupi não afetou o rendimento da mamoneira, diferentemente das plantas de milho que reduziram a produtividade da mamona quando consorciadas.</span></p><!--[if gte mso 9]><xml> <w:LatentStyles
