“…Results in Northern Africa diverged as well: in Mekele, Ethiopia, predicted productivity values from this method and the EPI model were 6.4 and 4.6 kg m −2 yr −1 , respectively, and in Agadir, Morocco, predicted productivity values were 5.3 and 4.0 kg m −2 yr −1 , respectively. Reported values in these regions thus far are well below the numbers predicted by either method (Arba, Benismail, & Mokhtari, 2002; Arba, Falisse, Choukr‐Allah, & Sindic, 2017; Boujghagh & Bouharroud, 2015; Gebretsadik, Animut, & Tegegne, 2013), suggesting that significant gains in yield may be achieved through fertilization and increasing planting density in these areas. In Northeast Brazil, yields predicted by the two methods were similar and were well above reported values in the region, which averaged 0.7 kg m −2 yr −1 and showed very high variability (Menezes, Simoes, & Sampaio, 2005).…”

Crassulacean acid metabolism (CAM) crops are important agricultural commodities in water-limited environments across the globe, yet modelling of CAM productivity lacks the sophistication of widely used C3 and C4 crop models, in part due to the complex responses of the CAM cycle to environmental conditions. This work builds on recent advances in CAM modelling to provide a framework for estimating CAM biomass yield and water use efficiency from basic principles. These advances, which integrate the CAM circadian rhythm with established models of carbon fixation, stomatal conductance and the soil-plant-atmosphere continuum, are coupled to models of light attenuation, plant respiration and biomass partitioning. Resulting biomass yield and transpiration for Opuntia ficus-indica and Agave tequilana are validated against field data and compared with predictions of CAM productivity obtained using the empirically based environmental productivity index. By representing regulation of the circadian state as a nonlinear oscillator, the modelling approach captures the diurnal dynamics of CAM stomatal conductance, allowing the prediction of CAM transpiration and water use efficiency for the first time at the plot scale. This approach may improve estimates of CAM productivity under light-limiting conditions when compared with previous methods.

“…It has good nutritional value so that it used as food and as sources of antioxidants (Asma et al, 2017). Additionally, it plays an important role in feeding ruminant species in arid and semi-arid areas (Arba et al, 2002). Cactus pear fruit has medicinal properties especially in traditional systems from time immemorial (Leem et al, 2016 andGouws et al, 2019).…”

field experiment was conducted during 2018 and 2019 seasons on El-shamia cactus pear plants orchard about eight years old, grown in sandy soil under drip irrigation system from a well located in Abu Ghaleb area, "Cairo-Alexandria desert road" about 50 km from Cairo, Egypt. The aim of study was the evaluation of the effect of cattle manure soil application rates; i.e. 20, 30 and 40 kg/plant and humic acid at 3 rates; i.e. 0, 10 and 20 g/plant as well as their interactions on growth, cladodes nutrients content, yield and fruit quality and investment ratio of cactus pear plants. Resulted showed that increasing cattle manure rates induced a progressive enhancement of the growth, cladodes nutrients content, yield and fruit quality. Moreover, humic acid at 20 g/plant surpassed the other two tested rates in enhancing the previously mentioned studied traits. Furthermore, cattle manure and humic acid as well as their combinations had positive effects on net profit and investment ratio. Finally, it is preferable to apply cattle manure at 40 kg/plant combined with humic acid at 20 g/plant to enhance growth, yield and fruit quality as well as cladodes nutrients content of El-shamia cactus pear. Besides, cattle manure at 30 kg/plant combined with humic acid at 20 g/plant attained the highest value of total revenue per feddan, net profit per feddan and investment ratio. The effects of cattle manure and humic acid as well as their combinations were cumulative and the second season was better than the first season in productivity and net profit as well as investment ratio.

“…In Morocco, cactus pear culture plays a prominent role in the rural populations. It is a source of food for humans and feeds for livestock and an appropriate crop for land rehabilitation in the arid regions (Arba et al, 2002). This drought-tolerant crop has various agro-inustrial uses such as cosmetics and pharmaceutical products (Barbera et al, 1995).…”

Genetic diversity and relationship among a set of 18 cactus pear genotypes, with different degrees of resistance to cochineal scale insect (Dactylopius opuntiae), was estimated using eight simple sequence repeat (SSR) markers. The genotypes used belong to four Opuntia species (O. engelmanii, O. ficus indica, O. robusta, and o. dillenii). The analysis revealed a total number of 56 alleles (Mean = 7) and an average genetic diversity index of 0.76 with genetic distances ranging from 0.00 to 1.00 at eight microsatellite loci in 18 Moroccan cactus pear genotypes. All microsatellites used were found to be highly informative, with mean polymorphic information content (PIC) estimated at 0.72. Genetic relationship estimated using the neighbor-joining (NJ) method and the principal coordinate analysis (PCoA), showed that the 18 genotypes were successfully assigned to four clusters, separated according to their taxonomy distribution and their levels of resistance to D. opuntiae. The results of this study demonstrated that the Moroccan cactus pear genotypes evaluated are highly divergent and that these genotypes will be useful for future crossing programs to improve the genetic diversity in Opuntia for resistance to D. opuntiae.
