“…A fim de verificar a produção de forragem e respostas estruturais do clone de palma forrageira OEM sob diferentes lâminas e frequências de irrigação Pereira et al (2021) verificaram que a lâmina de água de 77% da evapotranspiração da cultura eleva a produtividade de forragem, podendo ser adotado a frequência de irrigação de 7 a 28 dias. Amorim et al (2017) observaram que quando há presença de cobertura morta no solo a palma eleva a taxa de acúmulo de matéria seca, com redução no ciclo da cultura, em comparação ao cultivo sem uso de cobertura, adicionalmente, verificaram-se modificações nas fenofases com aplicação de lâminas de irrigação.…”

O sucesso do agronegócio no setor pecuário, depende da oferta de forragem para os animais, especialmente em zonas semiáridas, onde as características climáticas e a baixa disponibilidade de alimento podem dificultar a atividade. Diante disso, o uso de práticas agrícolas que melhorem a resiliência agrícola dos cultivos e possibilitem a oferta de forragem durante todo o ano para os animais torna-se imprescindível. Dentre tais práticas, destacam-se: o uso de espécies adaptadas as condições climáticas, escolha da configuração de cultivo, a densidade de plantio e orientação de cultivo. Nesse contexto, duas culturas que merecem destaque em ambientes quentes e secos são palma forrageira e sorgo forrageiro, ambas apresentam elevada eficiência no uso dos recursos, com produtividade satisfatória, além da existência de trabalhos que evidenciam os benefícios na associação dessas culturas na dieta alimentar dos animais. Dessa forma, na presente revisão, objetivou-se analisar as melhorias produtivas e estruturais das culturas da palma e sorgo sob adoção de práticas de resiliência agrícola. Os achados desta revisão, podem servir como subsídios para o planejamento da produção de forragem, ao tempo em que sugerem que a adoção de práticas adequadas (i.e. irrigação, consorciação, orientação de cultivo e densidade) e suas combinações no sistema de produção permitem um melhor aproveitamento dos recursos naturais e, com isso, maiores acúmulos de biomassa, constituindo-se em fatores determinantes para o êxito na produção.Palavras-chave: configuração de cultivo, densidade e orientação de plantio, Opuntia stricta, Nopalea cochenillifera, Sorghum bicolor. Agricultural resilience in intercropped forage cactus-sorghum cultivation in a semi-arid environment: A review A B S T R A C TThe success of agribusiness in the livestock sector depends on the supply of fodder for animals, especially in semi-arid areas, where climatic characteristics and low food availability can hamper activity. Therefore, the use of agricultural practices that improve the agricultural resilience of crops and make it possible to offer fodder throughout the year for animals becomes essential. Among such practices, the following stand out: the use of species adapted to climatic conditions, choice of cultivation configuration, planting density and cultivation orientation. In this context, two crops that deserve to be highlighted in hot and dry environments are forage cactus and forage sorghum, both have high efficiency in the use of resources, with satisfactory productivity, in addition to the existence of studies that show the benefits in the association of these cultures in the diet animal feed. Thus, in this review, the objective was to analyze the productive and structural improvements of palm and sorghum crops under the adoption of agricultural resilience practices. The findings of this review may serve as inputs for the planning of forage production, while suggesting that the adoption of appropriate practices (i.e. irrigation, intercropping, cultivation and density guidance) and their combinations in the production system allow for a better use of natural resources and, with this, greater accumulations of biomass, constituting determining factors for success in production.Keywords: cultivation setting, density and orientation planting, Opuntia stricta, Nopalea cochenillifera, Sorghum bicolor.

“…The literature shows results of photosynthesis evaluations and other important characteristics of gas exchange in cactus pear under irrigation (Alves et al, 2020), as well as studies on the effects of irrigation depths and frequencies in different cactus pear varieties on growth (Pereira et al, 2015;Dantas Neto et al, 2020), soil water balance (Pereira et al, 2017), structural characteristics, and forage biomass production (Pereira et al, 2021). In addition to water availability, the way water is applied, through different irrigation systems, can influence the volume of moist soil, modifying root growth and root biomass production, which will reflect on the biomass production capacity of the forage crop, as studies (Shao et al, 2008;Edvan et al, 2013) confirm the beneficial effects of soil moisture on the development of the root system and plant productivity.…”

The objective was to evaluate the effect of different irrigation systems and harvest frequencies on the cultivation of cactus pear. The study was conducted in the semi-arid region, in the municipality of Russas, CE, Brazil. The experiment was a split plot randomized block design, with four replications. Plots were represented by irrigation systems (surface drip, microsprinkler, Micro Spray Jet, and conventional sprinkler) and subplots by harvest frequencies (6, 9, 12, and 18 months). Cactus pear biomass production characteristics were evaluated. Most of the productive characteristics evaluated were influenced by harvest frequency and irrigation system. The harvest frequency of 12 months combined with conventional sprinkler system resulted in a total dry biomass production of 16,400 kg ha −1 . The conventional sprinkler system showed the highest number of second-order cladodes (4.9 cladodes plant −1 ). The conventional sprinkler and Micro Spray Jet systems showed the highest values for various structural characteristics. For water use efficiency (WUE), the highest value was found at the frequency of six months (8.46 kg ha −1 mm −1 ). Regarding the effects of irrigation system on WUE, the highest values were observed with the conventional sprinkler system (8.20 kg ha −1 mm −1 ). The harvest frequency of 12 months combined with the conventional sprinkler system presents better results in the evaluated productive characteristics, mainly the cactus pear production by area.

Climate change significantly impacts agriculture and forage production, requiring the implementation of strategies toward increased water and energy use efficiency. So, this study investigated the yield of forage cactus (Opuntia stricta (Haw.) Haw) under different irrigation depths using brackish groundwater (1.7 dS m−1), whose management was based on reference evapotranspiration (ETo) estimated by the Hargreave–Samani (HS) and Penman–Monteith (PM) equations. The research was conducted in Independência, Ceará, Brazil, under the tropical semi-arid climate. A randomized block design in a 2 × 5 factorial scheme was employed, varying the ET0 estimation equations (HS and PM) and irrigation levels (0; 20; 40; 70; and 100% of total required irrigation—TRI). Growth, productivity, and water use efficiency variables were evaluated at 6, 12, and 18 months after treatment initiation. The economic analysis focused on added value, farmer income, and social reproduction level. The results showed no isolated effect of the equations or their interaction with irrigation depths on the analyzed variables, suggesting that irrigation management can be effectively performed using the simpler HS equation. Furthermore, there was no statistical difference between the means of 100% and 70% TRI as well as between 70% and 40% TRI for most variables. This indicates satisfactory crop yield under deficit irrigation. Dry matter productivity and farmer income at 12 months resulting from complementary irrigation with depths between 40% and 70% of TRI were significantly higher than under rainfed conditions. The 70% depth resulted in yields equivalent to those at 100% TRI, with the social reproduction level being achieved on 0.65 hectares in the second year.
