“…Sorghum-cactus pear intercropping showed higher water use efficiency under severe drought because of lower evapotranspiration, which resulted in improved biomass production (Lima et al 2018). Similarly, Diniz et al (2017) reported that sorghum was dominated by cactus pear in intercropping indicating a higher competitive capacity of cactus pear compared to sorghum. However, in intercropping overall biomass was increased in comparison to monocultures due to lesser exposed ground area which improved moisture conservation under the high temperatures.…”

Cereal-legumes intercropping is among the most economical and effective agronomic strategies to boost forage biomass production, nutritional quality and monetary returns. This review synthesizes the research findings on how intercropping affects productivity, quality, competitiveness and economic viability of sorghum-legumes mixed, row and strip intercropping systems under varied pedo-climatic conditions. Though component crops show yield reductions in row (additive and row-replacement series), mixed (seed blended crops) and strip intercropping systems, in general overall productivity per unit land area increases to a great extent. The significantly higher resource capturing with better utilization efficacy by intercrops in temporal and spatial dimensions helps explain their greater productivity. In addition, forage intercrops result in improved nutritional quality as legumes contain protein in double quantity than cereals.

“…The WUE values of the intercropped were higher than the monoculture with irrigation depths from 1096 mm. In terms of income, Diniz et al (2017) found that increasing irrigation depths increased forage production in the forage cactus-sorghum intercropping, due to the benefits of forage sorghum cultivation.…”

“…Nevertheless, one of the main ways of assessing whether a syndicated system is more viable than a monoculture is to use competitive indices, which show how the components of a intercropping utilize the resources available in the agroecosystem. Among the main competitive indices we can mention: land use efficiency (LUE), relative density coefficient (RDC), competitiveness ratio (CR), aggressiveness (A) and system productivity index (SPI) (Sadeghpour et al, 2013;Yilmaz et al, 2015;Diniz et al, 2017). Diniz et al (2017) concluded that the forage cactus-sorghum intercropping obtained higher biological efficiency and competitive ability than the exclusive systems of both crops.…”

The same authors observed that the intercropping LUE obtained a value of 1.51, indicating that the exclusive system would need 51% more land to have similar yield.…”

Water scarcity, climatic conditions and low availability of fodder produced in Caatinga are some of the main problems faced by farmers in the Brazilian semiarid region. Therefore, the objective of this paper is to review some agricultural resilience practices that aim to increase forage production in the Brazilian semiarid. Several studies have shown that the use of fodder plants tolerant to this type of environment is essential to improve the production of ruminant feed. Among these, we highlight the forage cactus, which is rich in water, energy and minerals and highly tolerant to water deficit. Millet, in turn, is another plant that adapts to this environment, presenting better nutritional characteristics, besides being a more fibrous vegetable, and can be associated with cactus in the diet of the herds. This association can be done through the intercropping, which allows the simultaneous cultivation of two or more species in the same area, aiming at the most efficient use of available natural resources. The use of irrigation events with minimal and regular water use in cactus crops has been shown to be a very promising practice. However, the scarcity of this resource in semiarid regions, adding to this increasing salt concentrations in the springs, requires proper management. Additionally, other agricultural resilience practices, such as mulching, can directly contribute to reducing the need for irrigation, conserving soil moisture, decreasing soil thermal amplitude, improving its chemical, physical and biological properties, contributing to improved agricultural yields.

“…and Opuntia spp. ), can contribute to increases in biomass yields in agricultural areas, improving the use efficiency of local natural resources (Diniz et al, 2017). The forage cactus stands out as a forage alternative in semiarid regions due to its high potential of phytomass production and energy value, richness of non-fibrous carbohydrates, ruminant acceptability, large water reserve and easy propagation (Pereira, Leite, Cavalcante, & Lucena, 2018).…”

Forage cacti can contribute to increases in biomass yields in agricultural areas, improving the use efficiency of local natural resources. Forage cactus stands out as a forage alternative in semi-arid regions due to its high potential of phytomass production and energy value, large water reserve and easy propagation. The objective of this study was discriminate as morphometric characteristics of Nopalea cochenillifera cladodes in relation to Little and Giant Sweet clones. This research was conducted from March 2016 to July 2019. The design used was randomized blocks with five replicates using the forage cactus clones Little and Giant Sweet of Nopalea cochenillifera (L.) Salm-Dyck. The experimental unit was an area of 126.0 m2 (12.6 x 10.0 m). Study sample is composed of 1018 cladodes (581 of Little Sweet clone) and (437 of Giant Sweet clone), randomly collected. Variables evaluated were the cladode length, width, thickness, area weight. T-tests, Pearson correlation coefficients, discriminant analysis and canonical variables analysis were used to evaluate, compare and discriminate the morphometric characteristics of forage cactus clones. The Giant Sweet clone presented the highest means for the variables length, width, area and weight. Fisher's discriminant function verified a 99.41% hit rate to differentiate groups of forage cactus clone. The hit rate for Little Sweet clone was of 98.97%, while for Giant Sweet clone was of 100.00%. With two canonical variables the explanation rate of the morphometric characteristics for the behavior of forage cactus clones is higher than 90%. Morphometric characteristics of cladodes can be used as parameters that help in the identification of Nopalea cochenillifera clones with high discriminatory power.
