“…This shows that the 40% ETc and 120% ETc regimes are mainly related to the growth characteristics of the plant, while the controlled water deficit of 80% ETc has a direct influence on the yield of the IPA clone. These effects may be associated with the presence of more available water, favoring greater development and the emission of cladodes (Arba et al 2018). Although there is no strong association, the CTN influences the productivity of the forage cactus, mainly in the dry matter gain; a similar trend was observed by Neder et al (2013).…”

Forage cactus species exhibit distinct morphological characteristics, which have a relationship to yield and can be affected by different water conditions. The objective was to analyze, with the principal components analysis (PCA), the association between morphological and productivity variables in forage cactus clones in different water regimes. We cultivated, in Serra Talhada, Brazilian semiarid, the Miúda (MIU), Orelha de Elefante Mexicana (OEM) and IPA Sertânia (IPA) clones under four water regimes based on crop evapotranspiration – ETc (0%, 40%, 80% and 120% ETc). Between the years 2016 and 2018, morphological and crop productivity data were obtained. Two main components explained >82% of the total variability of the data, and the relationship between morphological and production variables depended on the clone and the water regime. The production of fresh and dry matter was more influenced by the morphological characteristics in the MIU and OEM clones. The IPA clone showed no correlation between the variables analyzed, regardless of the water regime. PCA can be used to understand the growth dynamics of plants and to identify the water conditions that act in the production of cactus clones, favoring better management in the cultivation of culture.

“…Considering the fruit chemical quality, all parameters measured did not vary in the function of the irrigation: irrigation did not decrease the quality. Another beneficial effect of irrigation is the intense increase of the shoot number emitted per cladode in the three varieties as reported in Arba et al (2018).…”

“…It occupies an important area of about 150 000 ha, but plantations are often poorly managed and usually not irrigated. Recently, high density plantations of cactus pear were established with drip irrigation in South Morocco, notably in the areas of Haouz, Tiznit and Guelmim (Arba et al, 2018). The plant has the reputation of low water demand (Nobel, 2002;Nobel & Bobich, 2002) and of rarely requiring irrigation in the Mediterranean region (Nobel, 2002;Inglese, 2010).…”

<p>Most plantations of cactus pear are not irrigated in Morocco and fruits are tiny. The impacts of irrigation during flowering (FLO) and fruit growth (FRG) on fruit yield and quality were monitored along two years on three varieties of cactus pear. In 2011, irrigation treatments were: T1 (0 mm), T2 (30 mm during FLO and 30 mm during FRG) and T3 (30 mm during FRG only). In 2012, irrigation treatments increased to 60 mm during FLO and FRG. The irrigation treatments were applied in 8 (T3) or 16 (T2) watering, once every three days. Interactions between varieties and treatments were significant for fruit yields and for yield components. In 2011, T2 and T3 irrigations had a negative effect on ‘Aissa’ and ‘Moussa’ (-2.8 kg/plant) and T2 had a positive effect on ‘Achefri’ (+2.7 kg/plant). Fruit quality was not affected by irrigation. In 2012, all the varieties responded positively to irrigation: ‘Achefri’ and ‘Aissa’ yielded very significantly more with T3 (plus 63 % and 30 % resp.) and ‘Moussa’ with T2 (+30 %). All irrigations increased fruit number and size. Irrigation had no significant effect on the fruit quality or slightly decreased the content of total sugars and titratable acidity</p>

“…Despite adapting to arid and semiarid environments (Arba et al 2018;Liguori et al 2013), the cactus is strongly influenced by environmental conditions . According to Nobel (2001), regions with an annual rainfall between 400 and 800 mm and an average air temperature between 16 and 2 °C, favour rainfed cultivation for the cactus.…”

Productivity, bromatological composition and economic benefits of using irrigation in the forage cactus under regulated deficit irrigation in a semiarid environment

The use of irrigation can improve the productivity and nutritional quality of the forage cactus in environments with a water deficit, resulting in profit to the producer. The productive performance, bromatological composition and economic benefits of using irrigation were investigated in this study with forage cactus clones regulated deficit irrigation (RDI). The study was conducted in an experimental design of randomised blocks, in a factorial scheme with subdivided plots. The plots consisted of water regimes based on the crop evapotranspiration (ETc) (rainfed, 40, 80 and 120% ETc). The cactus clones ['Miúda' (MIU), 'Orelha de Elefante Mexicana' (OEM) and 'IPA Sertânia' (IPA)] comprised the subplots. The total number of cladodes per plant, the fresh and dry matter yields and the bromatological composition were evaluated. Economic viability was assessed using the net revenue and benefit to cost ratio (BCR). The irrigation depths did not increase the yield of the clones. The OEM clone showed 276 and 343% greater fresh and dry matter production, respectively, when compared to the IPA clone; however, when compared with the MIU clone, it was 63%, both on a fresh and dry matter production. The water regimes had no effect on the nutritional quality of the cactus. Only IPA showed no profit during the first cycle (BCR < 1). It can be concluded that planting one irrigated hectare with the OEM and MIU clones offer economic returns starting from the first production cycle (18 months).
