“…This denotes that the formation and development of the peanut grains were compromised by the increases in salinity of the irrigation water. Production losses caused by increases in salinity were also found by Correia et al (2009) for peanut plants of the cultivar BR-1, and by Tagliaferre et al (2018) for cowpea plants. The use of the pulse irrigation method resulted in a grain fresh weight 25.3% higher than the use of continuous irrigation.…”

Pulse irrigation may be more advantageous for peanut crops than continuous irrigation, when using brackish water. However, studies on pulse irrigation with brackish water considering the environmental conditions of the Northeast region of Brazil using are incipient. Therefore, the objective of this study was to evaluate the effect of using brackish water for pulse and continuous dripping irrigations on the grain yield and production characteristics of peanut (Arachis hypogaea L.) crops. A completely randomized block design with four repetitions was used, in a 6*2 factorial arrangement consisted of six electrical conductivities of the irrigation water (EC; 0.2, 1.6, 2.8, 4.0, 5.2, and 6.4 dS m-1) set by adding NaCl to the irrigation water, which originally had 0.2 dS m-1, until reaching the respective EC; and two irrigation methods (pulse and continuous). The evaluated variables were fresh and dry weights of shoot, 10 grains, pods, grains, and production; number of pods and grains; and percentages of empty pods (EP%) and perfect grains (PG%). The addition of salt to the irrigation water negatively affected all variables studied, except for EP% and PG%. The lowest EP% were found for the pulse irrigation, which increased the pod and grain yields, regardless of the EC of the irrigation water. Under the conditions of the present study, the use of brackish waters with electrical conductivities of up to 2.98 dS m-1 is viable for peanut production.

“…Sá et al (2018) found morphophysiological changes in cowpea plants, with reduction in their photosynthetic rate, due to stomatal restrictions and damage to the photosynthetic apparatus. Thus, the production of photoassimilates directly infl uences the production performance of cowpea (TAGLIAFERRE et al, 2018).…”

“…Similarly, Oliveira et al (2015) found that the production of pods per cowpea plant under salt stress was reduced by 50% and that the number of seeds per pod (NSPO) decreased by 1.5 seeds per pod, for each unit increase in the electrical conductivity of irrigation water. According to Tagliaferre et al (2018), each unit increase in the electrical conductivity of irrigation water above the salinity threshold (3.3 dS m -1 ) lead to reductions of up to 25% in grain yield. Despite that, there is divergence in the reduction of cowpea production as a function of salt stress, caused by the different degrees of tolerance between varieties (DANTAS et al, 2002).…”

Cowpea suffers signifi cant production losses when subjected to salt stress, but the response varies among genotypes. The objective of this study was to evaluate the phenology and production of traditional cowpea seeds under saline water irrigation. The experiment was conducted in two stages, the fi rst one in a greenhouse to evaluate the phenology and production of cowpea genotypes and the second one in the laboratory to assess the viability and vigor of the seeds produced in the fi rst stage. The treatments resulted from the combination of two salinity levels of the irrigation water (0.5 and 4.5 dS m -1 ) and 14 traditional cowpea varieties (Boquinha, Ceará, Costela-de-vaca, Lisão, Canário, Pingo-de-ouro, Roxão, Branco, Canapum-branco, Canapum-miúdo, Baêta, Coruja, Paulistinha, and Sempre-verde) acquired from traditional farmers in the western region of Rio Grande do Norte, Brazil. Canário, Baêta, and Coruja varieties have a higher number of fl owers per plant and earlier fl owering. Salinity reduced the number of fl owers per plant, increased abortion in all traditional varieties and reduced production in the early varieties Branco, Canapum-miúdo, Baêta, and Coruja. Cultivation under saline water irrigation did not affect the viability of the seeds from the second generation of cowpea, but reduced the vigor of the seeds of the varieties Lisão, Pingo-de-ouro, Roxão, Branco, Canapum-branco, Canapum-miúdo, Baêta and Coruja. The traditional varieties Boquinha, Ceará, Costela-de-vaca, Canário, Paulistinha and Sempre-verde are indicated for the production of cowpea seeds under irrigation with saline water.

“…For Tagliaferre et al (2018), crops such as beans and onions cannot be grown in areas with saline problems, with their resistance being 1 and 1.2 dS m -1 respectively. Already for Granja et al (2019), although salinity reduces the vegetative growth and productivity of cowpea, it did not influence the qualitative aspects of fruits and seeds, causing a slight increase in the harvest index.…”

“…Soils with high clay content have a damaged structure and reduced natural porosity, reflected in the decrease in drainage and plant growth, in addition to making it difficult to leach salts present in the profile (PEDROTTI et al, 2015). For Tagliaferre et al (2018), the harm caused by salinity to plants is associated with the reduction of the osmotic potential of the soil solution, nutritional disorders, particular effects of ions or the combination of these factors.…”
