Resumo: | Cactus pear is an alternative for animal feed in the semiarid region, and its productive characteristics can be improved with little irrigation. The objective of this work was to assess the agronomical performance and water use efficiency (WUE) of two cactus pear cultivars subjected to different irrigation water depths and define the best material genetic material for irrigated conditions in the semiarid region of the state of Minas Gerais (MG), Brazil. The experiment was conducted in Montalvânia, MG, during one year (2017-2018) using six treatments consisting of irrigation water depths based on the reference evapotranspiration (ET0) (without irrigation, 15%, 30%, 45%, 60%, and 75% ET0) and two genetic materials (Opuntia ficus-indica Mill. cv. Gigante, and Nopalea cochenillifera Salm-Dyck cv. Miúda). A randomized block design was used, in a with split-plot arrangement consisting of irrigation treatments in the plots and genetic materials in the subplots, with four replications. Growth evaluations were carried out from the third month after planting to the end of the growing cycle. Production variables and WUE were evaluated at the harvest. The irrigation water depths affected the growth variables, significantly (p<0.05). The water depths of 40% to 50% ET0 provided higher fresh and dry matter yields; the cultivar Miúda showed better performance than the Gigante. The WUE was affected by the irrigation water depths; the cultivar Miúda was the best option for the crop. |

A palma forrageira é uma alternativa para alimentação animal na região semiárida, sendo possível aprimorar suas características produtivas com um mínimo de irrigação. Objetivou-se analisar o desempenho agronômico e a eficiência de uso da água (EUA) de duas cultivares de palma forrageira submetidas a diferentes níveis de irrigação, bem como definir qual o melhor material genético para condições irrigadas no semiárido mineiro. O experimento foi conduzido em Montalvânia-MG durante um ano (2017-2018) envolvendo seis tratamentos de lâminas de irrigação correspondentes a frações da evapotranspiração de referência (ET0) (T1, sem irrigação; T2, 15%; T3, 30%; T4, 45%; T5, 60% e, T6, 75% da ET0) e dois materiais genéticos (Gigante - Opuntia fícus-indica Mill. e Miúda - Nopalea cochenillifera Salm-Dyck). Utilizou-se o delineamento em blocos casualizados em esquema de parcelas subdivididas, em que as parcelas foram os tratamentos de irrigação e as subparcelas foram os materiais genéticos, com quatro repetições. A partir do terceiro mês após o plantio e durante um ciclo de cultivo efetuaram-se as avaliações de crescimento e, na colheita foram avaliadas as variáveis de produção e a EUA. Constatou-se que as lâminas de irrigação influenciaram significativamente (p<0,05) as variáveis de crescimento. As lâminas de 40 a 50% da ET0 proporcionaram maior produtividade de matéria verde e matéria seca e a cultivar Miúda superou a ‘Gigante’. A EUA foi influenciada pelas lâminas de irrigação, sendo a cultivar Miúda a melhor opção para o cultivo.
