“…O feijão-guandu (Cajanus cajan (L.) Millsp.) pertencente da família Fabaceae, é uma leguminosa com ciclo anual ou semiperene de porte arbustivo (Araújo et al, 2019). Esta cultura é de suma importância para os países tropicais e subtropicais, sendo os principais situados no continente africano e asiático.…”

“…O feijão-guandu é muito utilizado como adubação verde, com o intuito de fornecer matéria orgânica e nitrogênio par o solo. Esta leguminosa apresenta sistema radicular profundo e ramificado, o que possibilita a restauração química dos solos degradados, a partir da fixação biológica de nitrogênio e solubilização do fósforo ligado ao solo, além de permitir a sobrevivência da cultura em regiões com baixa disponibilidade hídrica (Verslype et al, 2015;Araújo et al, 2019;Sewsaran et al, 2019).…”

The low forage productivity in the Brazilian semi-arid is linked to water scarcity and climatic conditions, these abiotic disturbances affect the development of livestock and the local economy. Seeking to circumvent the situation, the use of forage species adapted to climatic conditions is of paramount importance, such as forage cactus, a crop rich in nutrients, much appreciated by animals, but lacking in fiber and protein, making it necessary to use other forage plants like sorghum, millet, pigeon pea and forage sunflower, both species have high levels of fiber and protein, and with this, they complement each other and enable the production of more balanced diets for herds. However, the higher yield of crops is observed with the implementation of resilient practices such as irrigation, adoption of mulch, intercropping, which promotes more sustainable systems with high forage potential. In this review, the objective was to evaluate the use of different agronomic practices to increase the productivity and sustainability of forage cactus crops and crops of regional appeal to the Brazilian semi-arid region. It is concluded that the sustainable intensification of agricultural crops, through complementary irrigation, mulch, intercropping with forage cactus, and plant species adapted to the Brazilian semi-arid region, can promote an increase in forage production without adverse effects on ecosystems.

“…Soil salinity is a worldwide problem that affects approximately 10% of all soils and half of the irrigated areas in the world (Kamran et al, 2020;Singh, 2021). Salinization is a process that occurs in poorly managed soils, usually with poor drainage conditions, indiscriminate use of fertilizers, low-quality water used for irrigation, or natural causes due to the weathering of rocks, which have high levels of soluble salts (Aderaldo et al, 2020;Araújo et al, 2019). A soil is considered saline when it has an electrical conductivity greater than 4 dS/m (40 mM) (Jesus & Borges, 2020).…”

Cowpea, Vigna unguiculata (L.) Walp, is a very important Fabaceae in the diet of families in the northeast region of Brazil. This plant species is among the different cultures affected by the root-knot nematode. In this region, in addition to phytonematodes, another condition that affects cowpea productivity is salinity, one of the main abiotic limiting factors. The cultivar Pitiúba, however, has good adaptability to salt stress conditions. However, information on the behavior of root-knot nematodes in an environment with high levels of salinity for this crop is still scarce. Based on the above, the objective of this work was: 1) to evaluate the hatchability of J2 of Meloidogyne enterolobii in 100mM NaCl solution; 2) evaluate the motility and infectivity of J2 of M. enterolobii in saline solution at the levels of 0, 25, 50, 75, 100, 125, 150, 175, 200, 300, and 400mM; 3) to investigate the impairment of the development of M. enterolobii in cowpea Pitiúba under irrigation with NaCl solution at 100mM. It was found that J2 hatching, motility, and infectivity of juveniles of M. enterolobii were not affected by the levels of salinity tested in vitro. In Pitiúba, irrigation with 100 mM saline solution considerably affected the development of juveniles of the pathogen in the roots.
