Management practices can affect the phenology and, consequently, the harvest time and crop production level of forage cactus. This study aimed at evaluating the effect of irrigation depths and cropping systems on the phenophases and cutting time of the forage cactus Opuntia stricta (Haw.) Haw. The experimental design was a randomized block with split plots and four replications. Irrigation depths based on reference evapotranspiration (8.75 %, 17.5 %, 26.25 % and 35 % ETo) and a control (0 % ETo) made up the plots, while cropping systems (exclusive cropping, exclusive cropping on mulch and forage cactus-sorghum intercropping) were distributed in the subplots. Cladode emission morphogenesis was used to define the phenological phases, while the extrapolation of the monthly dry matter accumulation rate was applied to obtain the cutting time. The use of irrigation depths significantly increased the phenophase II (higher emission of second-order daughter cladodes), decreasing the phenophase III, associated with third-order daughter cladodes. The phenophase III was lower in the exclusive cropping on mulch and forage cactus-sorghum intercropping systems, when compared to the exclusive cropping system. The ideal cutting time for irrigated forage cactus is 19 months, regardless of the cropping system. The exclusive cropping on mulch and forage cactus-sorghum intercropping systems significantly increased the monthly forage dry matter accumulation rate, with an earlier cutting time for the forage cactus-sorghum intercropping system (17 months).

“…Para as palmas Miúda e OEM, nesta pesquisa, até os 16 meses parece não ter atingido a fase de estabilização do crescimento da planta, o que também está de acordo com os resultados apresentados por Farias et al (2000) que avaliaram frequências de corte em palma forrageira cultivada em dependência da chuva (dois e quatro anos de intervalo para o corte) e verificaram maiores produções para a palma cortada com intervalo de quatro anos, quando foram conservados os artículos primários. Quando o corte foi realizado conservando--se os artículos secundários foi obtida semelhante produção de forragem nas diferentes frequências de corte.…”

“…O menor intervalo para o corte da palma é importante para obtenção de alimentos em menor tempo aos rebanhos (Almeida, 2011). Por outro lado, de acordo com Farias et al (2000) maiores produções de palma podem ser obtidas em intervalos de corte maiores.…”

Índice de área de cladódio. Nopalea sp. Opuntia sp. resUMoA palma forrageira, recebendo aporte adicional de água, pode se constituir em alternativa alimentar para os rebanhos da região semiárida brasileira, entretanto são escassas as informações sobre as respostas produtivas e estruturais dos genótipos, assim como do intervalo de cortes da planta. Esta pesquisa teve o objetivo de avaliar as características produtivas e estruturais de genótipos de palma forrageira em diferentes intervalos de corte. O delineamento experimental foi em blocos completos casualizados com parcelas subdivididas tendo os genóti-pos dispostos nas parcelas e os intervalos de corte nas subparcelas, com quatro repetições por tratamento, totalizando 48 unidades experimentais. O experimento foi realizado no período de maio de 2014 a setembro de 2015, com três genótipos de palma forrageira, a orelha de elefante mexicana (OEM) (Opuntia stricta (Haw.) Haw.), IPA 20 (Opuntia ficus indica (Mill)) e a miuda (Nopalea cochenillifera Salm. Dyck) e intervalos de corte de 4, 8, 12 e 16 meses após o plantio. A OEM aos 16 meses apresentou maior massa de forragem (t de matéria seca/ha e matéria verde/ha) em comparação com a miuda e IPA 20 nos diferentes intervalos de corte, tendo ainda maior taxa de acúmulo de forragem e melhor eficiência de uso da água. A miuda teve maior número de cladódios e cladódios mais leves. A OEM juntamente com a miuda apresentaram maiores índices de área de cladódio a partir de oito meses após o plantio comparada à IPA 20. Os genótipos assim como o intervalo de corte afetam as características produtivas e estruturais da palma forrageira. The spineless cactus receiving additional water may constitute alternative food for the flocks of the Brazilian semiarid; however, the information about structural and productive responses of genotypes, as well as the cutting intervals are scarce. This research aimed to evaluate the productive and structural characteristics of genotype at different cutting intervals. The experimental design was a randomized block with split plot (genotypes in the plots and cutting intervals in the subplots), with four replicates per treatment, totaling 48 experimental units. The experiment was conducted from May 2014 to September 2015, with three genotypes of cactus, the orelha de elefante mexicana (OEM) (Opuntia stricta (Haw.) Haw.) IPA 20 (Opuntia ficus indica (Mill.) and miuda (Nopalea cochenillifera Salm. Dyck) and at a cutting interval of 4, 8, 12 and 16 months after planting. The OEM at 16 months presented greater forage mass (t dry matter/ha and green matter/ha) compared to the miuda and IPA 20 at the different cut intervals, with a greater rate of forage accumulation rate and better water use efficiency. Miuda had more and lighter cladodes. The OEM together with miuda presented greater cladode area index from eight months after planting compared to IPA 20. The genotypes as well as the interval of cuts affect the productive and structural characteristics of spineless cactus. additional keYwordsCladode area ...

“…The practice of dense cultivation makes it possible to achieve greater forage production by area; however, the costs of establishment of plantation also are larger, and the cultural practices become more diicult and do not allow cultivation with other crops [59]. It is worth mentioning that spineless cactus extracts large amounts of nutrients from the soil.…”

The term "spineless cactus" is used in Brazil to designate cultivars of Opuntia icus indica Mill and Nopalea cochenillifera Salm Dyck. The spineless cactus was consolidated in Brazilian semiarid as a strategic fundamental food resource in several production livestock systems, constituting a plant with enormous productive potential. Thus, the spineless cactus has been widely cultivated and used for several decades, by enabling the animal feeding in critical periods of year because of its characteristics, morpho-anatomical and physiological (CAM), which makes it tolerant to long droughts, being a crop that presents high productivity in droughts conditions, when compared to other forages. Nevertheless, the spineless cactus is a crop relatively picky about soil and climate characteristics of region, presenting greater growth in fertile soils, as well as in regions where nightime temperatures are cool and the air humidity is relatively high. Although the crop be adapted to long droughts periods, many times it's necessary to perform irrigation in its production system, mainly in regions of low rainfall, for to supply its water needs, thus ensuring productivity and survival of crop. Therefore, the knowledge of characteristics of plant, as well as of appropriate management techniques to crop, is essential for the good performance of spineless cactus.
