“…On the other hand, effect of the intercropping was only noted on forage cactus canopy width (p < 0.05) (Figure 1) and there was no alteration in most features of the cladode, demonstrating that, in this configuration of cultivation, the sorghum crop did not affect forage cactus features. Nevertheless, Silva et al (2013) cite that forage cactus response may vary according to the intercropping.…”

“…The literature reports intercropping of forage cactus with various other vegetable crops (Silva et al, 2013), and the most common is the rainfed forage cactus sorghum configuration (Farias et al, 2000). Nonetheless, the efficiency of intercropping systems with this species, in comparison to its mono cultivation, depends on the secondary crop and on management (Silva et al, 2013).…”

A B S T R A C TThe effects of the forage cactus sorghum configuration and different irrigation depths on the growth, water use and efficiency of the forage cactus production system were investigated in this study. The experiment was conducted in the municipality of Serra Talhada, Pernambuco State, Brazil, between the years 2012 and 2013. Forage cactus was distributed in randomized blocks with factorial scheme and four replicates, in split plots (5 x 2), with five irrigation depths (0, 8.75, 17.5, 26.25 and 35% of the reference evapotranspiration, ET 0 ) and two cropping systems (forage cactus monocropping and forage cactus sorghum intercropping). Crop evapotranspiration was calculated through soil water balance. The ratio between crop and reference evapotranspiration, and land use and water use efficiencies, were estimated. Irrigation depths and the intercropping affected only forage cactus canopy width and cladode biomass. The ratio between crop and reference evapotranspiration increased with the increase of irrigation depths, while the highest water use efficiency based on dry matter occurred at irrigation depths higher than 1,096 mm year -1 in the intercropping (21.8 ± 6.8 kg ha -1 mm -1 ). Irrigation depths did not affect land use efficiency (0.83). Water depths from 1,096 to 1,202 mm year -1 are recommended in the forage cactus sorghum system. Crescimento, consumo de água e eficiência do consórcio palma-sorgo sob diferentes lâminas de água R E S U M OOs efeitos da configuração palma-sorgo e de diferentes lâminas de irrigação sobre o crescimento, consumo de água e eficiência do sistema de produção da palma foram investigados neste estudo. O experimento foi conduzido em Serra Talhada, PE, entre os anos de 2012 e 2013, com a palma disposta em blocos ao acaso, quatro repetições, em parcelas subdivididas (5 x 2) de cinco lâminas (0, 8,75, 17,5, 26,25 e 35% da evapotranspiração de referência) e dois sistemas de cultivo (palma exclusiva e consórcio palma-sorgo). A evapotranspiração real da cultura foi calculada por meio do balanço de água no solo. Estimou-se a razão evapotranspiração real e de referência, além das eficiências do uso da água e da terra. As lâminas de irrigação e a adoção do consórcio afetaram apenas a largura do dossel e a biomassa dos cladódios da palma forrageira. A razão evapotranspiração real e de referência aumentou com o incremento da lâmina de irrigação, enquanto as maiores eficiências do uso da água com base na massa seca ocorreram nas lâminas de água superiores a 1.096 mm ano -1 no consórcio (21,8 ± 6,8 kg ha -1 mm -1 ). As lâminas de irrigação não afetaram a eficiência do uso da terra (0,83). No sistema palma-sorgo, recomendam-se lâminas de água entre 1.096 e 1.202 mm ano -1 .

“…On the other hand, the adoption of mulching, despite being important in the production systems of various agricultural crops (Kumar & Dey, 2011), has not yet been reported for this plant. Intercropping of forage cactus with other crops is more common, but under rainfed conditions (Silva et al, 2013).…”

A B S T R A C TThe present study evaluated soil moisture (θ) in forage cactus plantations under resilience practices such as irrigation, mulching and intercropping with sorghum. The experiment was arranged in a randomized block design with five water availability conditions (0, 8.75, 17.5, 26.25 and 35% of the reference evapotranspiration), and three planting systems: forage cactus exclusive system (PE), forage cactus with mulch (PC) and intercropping between forage cactus and sorghum (PS). Water content was measured until a depth of 0.60 m. Meteorological data were recorded between June 2012 and June 2013. Water content was not affected by different resilience practices and the variation coefficient was low to medium (4.0 to 22.1%). The temporal variation of soil moisture was more affected by the changes in rainfall, while the physical properties (soil density, porosity and grain size) were decisive in the vertical variation. It was concluded that periods with rainfall events favor the alternation of practices to improve forage cactus resilience (irrigation, mulch and intercropping).Umidade do solo em lavouras de palma forrageira com práticas de melhoria da sua resiliência R E S U M ONo presente estudo a umidade do solo (θ) foi avaliada em lavouras de palma forrageira sob práticas resilientes, tais como irrigação, cobertura morta e consórcio com a cultura do sorgo. O experimento foi disposto em blocos ao acaso com parcelas de cinco condições de disponibilidade hídrica (0, 8,75, 17,5, 26,25 e 35% da evapotranspiração de referência) e subparcelas de três sistemas de cultivo: palma exclusiva (PE), palma com cobertura morta (PC) e consórcio palma-sorgo (PS). O monitoramento da umidade do solo foi feito até a profundidade de 0,60 m. Dados meteorológicos foram registrados entre junho de 2012 e junho de 2013. A umidade do solo não foi afetada pelas diferentes práticas para melhoria da resiliência e o coeficiente de variação foi de baixo a médio (4,0 a 22,1%). O aumento das lâminas de água, cobertura morta e as camadas mais profundas do solo promoveram menores variabilidades da θ. A variação temporal da umidade foi mais afetada pelas alterações da precipitação enquanto as propriedades físicas (densidade do solo, porosidade e frações granulométricas) foram decisivas na variação vertical. Conclui-se que períodos com ocorrência de eventos de chuva favorecem a alternância de práticas de melhoria da resiliência da palma forrageira (irrigação, cobertura morta e consórcio).
