Abstract:
ABSTRACT The deleterious effects of salt stress can be mitigated by the use of beneficial microorganisms. The aims of this study were to evaluate whether coinoculation with Bradyrhizobium and Trichoderma asperelloides alleviates salt stress in cowpea. The experiment was conducted in a greenhouse using pots filled with sterile soil. Seeds were sown and inoculated with Bradyrhizobium or coinoculated with Bradyrhizobium and T. asperelloides. At 15 days after sowing (DAS), the nitrogen-free nutritive solution was supplemented with 50 or 100 mmol L-1 sodium chloride (NaCl) to induce salinity. Unino

HIGHLIGHTS Saline stress did not affect the initial growth of the cowpea crop. The use of mulch provides better morphological results in the cowpea crop. Vegetal mulches as soil protection (sugarcane bagasse and bamboo straw) attenuated effect of salts on gas exchange of cowpea.

Abstract:
Cowpea provides the cheapest source of protein with an average range of protein content of 23–30%. However, cowpea growth, development, and yield are greatly affected by drought during flowering and pod filling in the sub-Sahelian areas. The best way to cope with this situation is to develop drought-tolerant cowpea varieties. The objective of this study was therefore to evaluate cowpea lines developed through mutagenesis using gamma radiation to assess their reaction under optimal and water-stressed conditions. The response of ten mutants-irradiated Moussa local was then evaluated in pots arra

Abstract:
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 abov

Abstract:
Purpose: To evaluate the effects of a phytoestrogen extract of cowpea (Vigna unguiculata) on malondialdehyde (MDA) and superoxide dismutase (SOD) levels, mitogen-activated protein kinase (MAPK) activity, as well as proliferation of fibroblasts in ovariectomized rat vagina. This is with a view to identify the optimal dose of a phytoestrogen supplement for use during the menopausal period of women.
 Methods: Wistar rats (Rattus norvegicus) were divided into five groups: negative control, ovariectomy, and ovariectomy groups treated with 1.25, 2.5, or 5 mg/kg of cowpea extract, respectively.

Genotypic variation in crop response to drought depends on agronomic, environmental and genetic factors, and only limited work has compared responses of crop species to water limitation. Twenty genotypes of peanut (Arachis hypogaea L.) and of cowpea (Vigna unguiculata (L.) Walp) were tested in lysimeters under well-watered (WW) and water-stress (WS) conditions during two seasons, a post-rainy season with high evapotranspiration and a rainy season with low evapotranspiration (ET), in order to assess: (i) variability in the agronomic response to stress within and between species across the seaso

ABSTRACT The objective of this work was to evaluate seeds of cowpea, cultivar BRS Tumucumaque, subjected to different water stresses induced by polyethylene glycol (PEG-6000) and mannitol and different salt stresses induced by NaCl and CaCl2 solutions. The water and salt stresses was evaluated in laboratory using completely randomized experimental designs in 2x6 factorial arrangements, with six osmotic potentials (0.0, -0.2, -0.4, -0.6, -0.8 and -1.0 MPa) and two stress inducers for each experiment, with four replications of 50 seeds.

Abstract:
Cowpea (Vigna unguiculata) is one of the world’s main crops, and it is a fundamental source of protein for semiarid regions population. In these regions, the use of high salts concentration water in irrigation systems is one of the major factors that contributes to reduced cowpea yield. One way to alleviate the negative effects of salinity is through the biostimulants application, which is a product that has beneficial substances to the plants metabolism. The aim of this study was to evaluate the application of biostimulant in cowpea cultivars under irrigation with saline water. The

The aims of this study were to study the biochemical metabolism alterations generated by saline stress in two cowpea cultivars: BRS Guariba (moderately tolerant) and BR3 Tracuateua (sensitive), and to investigate the action of brassinosteroid in attenuation of oxidative stress. The results for water content and damage index in cell membranes were similar. Plants with 24-Epibrassinolide hormone maintained their water content satisfactory and without any membrane extravasation, whereas, for plants with salinity these variables decreased considerably.
