“…It is important to highlight that the presence of organic matter in all treatments with salinity promoted greater K + increments when compared to soil without organic matter; however, the availability of this ion was directly affected by the increase in salinity, given the antagonistic effects promoted by the increase in the concentrations of Na + , Ca 2+ , and Mg 2+ , which reduce the availability of K + by displacing it from the cation exchange complex (Martínez et al, 2022). Similar results were presented by Rodrigues et al (2018), who evaluated the chemical attributes of a soil irrigated with saline water and found reductions in potassium concentrations in the soil as a function of the increase in irrigation water salinity up to 5 dS m -1 .…”

This study aimed to evaluate the influence of organic matter on the salt accumulation in three layers of soil cultivated with noni plants irrigated with brackish water, in open field and under partial shading conditions. The experimental design was in randomized blocks, arranged in a split-split-plot scheme with five replicates. The plots were constituted by the cultivation environments (open and shaded field), the subplots by the electrical conductivity of the irrigation water (0.3, 1.5, 3.0, 4.5, and 6.0 dS m-1), and the sub-subplots by the absence and presence of organic matter. At 110 days after application of the treatments, the electrical conductivity of the saturation extract and the potassium, sodium, calcium, and magnesium concentrations were determined in three soil layers (0-10, 10-20, and 20-30 cm). Partial shading reduced the total accumulation of salts and sodium in the soil compared to the open field. Increasing the electrical conductivity of irrigation water reduced potassium concentrations in the soil, but this effect is offset by the addition of organic matter, which releases potassium, calcium, and magnesium for plant nutrition. However, cattle manure increases sodium accumulation in the soil in treatments with the highest water salinity.

“…Similar results have been found by LESSA et al (2019), who have observed an increase in the salt level of the soil when using salt water to irrigate the sorghum crop. In addition, RODRIGUES et al (2018) have also reported similar results when verifying an increasing linear response of the electrical conductivity of the soil with the increase of the concentration of salts in the irrigation water.…”

O estresse salino prejudica o desenvolvimento inicial da cultura do amendoim. Contudo, seus efeitos possuem intensidade que dependem de outros fatores, como as espécies ou cultivar. Objetivou-se avaliar os efeitos do estresse salino no crescimento inicial de genótipos de amendoim. O experimento foi conduzido em estufa agrícola sob condições de vaso na Universidade da Integração Internacional da Lusofonia Afro-Brasileira em Redenção/CE. Os tratamentos foram: dois níveis de condutividade elétrica da água de irrigação (2,0 e 5,0 dS m-1); e cinco genótipos de amendoim (cultivar BR-1, Acesso 08, 28, 43 e 130). Foi implantado num esquema fatorial (2 × 5) sob delineamento inteiramente casualizado com cinco repetições. Aos 34 dias após a semeadura foram avaliadas as seguintes variáveis: número de folhas, altura de plantas, área foliar, diâmetro do caule, massa seca da parte aérea, condutividade elétrica do extrato de saturação do solo e o pH. A água de irrigação com condutividade de 5,0 dS m-1 reduz área foliar, altura de planta, diâmetro do caule, número de folhas e a matéria seca da parte aérea de genótipos de amendoim, cultivar BR-1, Acessos 08, 28, 43 e 130. Também eleva o pH e a condutividade elétrica do extrato de saturação, em relação à água de menor condutividade (2,0 dS m-1).

“…In the semi-arid region of Brazil, due to adverse climatic conditions, characterized by having in most of the year high temperatures, high evapotranspiration rates and low rainfall, distributed irregularly in space and time, the use of irrigation becomes indispensable for the agricultural exploitation. However, due to the high demand for good quality water, together with the need to produce food, the use of lower quality water in agricultural activities has become frequent (LIRA et al, 2015;MUNNS;GILLIHAM, 2015;RODRIGUES et al, 2018).…”

Yellow passion fruit is a fruit species widely cultivated throughout the Brazilian semi-arid territory, but its yield is affected by the quality of the waters of this region. In this context, the objective was to evaluate the gas exchange and production of passion fruit cv. BRS Rubi do Cerrado irrigated with waters of different cationic natures. The study was conducted in drainage lysimeters under greenhouse conditions in Campina Grande, PB, Brazil, in a randomized block design, and the treatments were eight cationic natures of irrigation water (S1 - Control; S2 - Na+; S3 - Ca2+; S4 - Mg2+; S5 - Na+ + Ca2+; S6 - Na+ + Mg2+; S7 - Ca2+ + Mg2+ and S8 - Na+ + Ca2+ + Mg2+) with three replicates. Plants in the control treatment were irrigated with water of low electrical conductivity (ECw = 0.4 dS m-1), while those of the other treatments were irrigated using water with ECw of 3.5 dS m-1. The treatments Na+ + Ca2+, Na+ + Mg2+ and Ca2+ + Mg2+ were prepared in the equivalent ratio of 1:1, and Na++Ca2++Mg2+ in the ratio 7:2:1, respectively. Water salinity of 3.5 dS m-1 reduced gas exchange, and stomatal conductance and transpiration were the most sensitive variables of passion fruit. The number of fruits of passion fruit cv. BRS Rubi do Cerrado decreased with water salinity, regardless of the cationic nature. The waters of calcic and calcic+magnesian nature caused the greatest deleterious effects on the production variables of passion fruit, at 259 days after transplanting.
