“…Corroborating the results obtained, Karimi et al (2021) found that the concentration of Mn in grapevine leaves shows a decreasing trend in response to salt stress. The same was obtained by Silva et al (2021b) in 'Galia' melon plants grown in Neossolo Regolítico (Entisol) and Argissolo Amarelo (Ultisol), where leaf Mn contents decreased by 41% with increasing salinity of the irrigation water from 1.0 to 6.0 dS m -1 .…”

Watermelon is cultivated in practically all Brazilian states; however, there are still disagreements as to the best way to propagate it. In addition, the Northeast region, the main producing region in the country, is increasingly facing the scarcity of low-salinity water. Given this context, this study aimed to evaluate the morphophysiology and mineral contents of the watermelon crop subjected to irrigation water of different electrical conductivities, using seedlings or direct seeding. A randomized block experimental design with split plots was used, with four replications. The plot was formed by the electrical conductivities of the irrigation water (0.3, 1.5, 3.0, and 4.5 dS m-1) and the subplot by the planting methods - DS = direct seeding, TP1 = transplanting of the seedling produced with water of moderate salinity (1.5 dS m-1), and TP2 = transplanting of the seedling produced with water of low salinity (0.3 dS m-1). The highest biomass accumulation was obtained in the direct seeding method. Salt stress increases the intrinsic water use efficiency in watermelon plants. The TP1 and TP2 planting methods led to the highest contents of P and K in the leaf. The increase in the salinity level increases the content of S and reduces the content of Cu and Mn.

“…Silva et al (2021b) observed a linear reduction of 53% in the Cu content in melon plants when the salinity of the irrigation water increased from 0.5 to 5.0 dS m -1 . However,Ekbic et al (2017) found an increase in Cu content along with the level of salt stress in watermelon genotypes tolerant to salt stress, grown in a greenhouse.…”

The use of saline water is one of the major challenges of agriculture, as it can cause nutritional imbalances and thus reduce crop yield. This study proposes to examine the efficiency of potassium nutrition as a salt stress-mitigating agent in melon grown in a protected environment. The experiment was laid out in a randomized-block design with ten treatments in a 2 × 4 factorial arrangement represented by two melon cultivars (McLaren and SV1044MF) and four nutrient solutions (S1 - standard nutrient solution, 2.5 dS m-1; S2 - nutrient solution salinized with NaCl, 5.0 dS m-1; S3 - nutrient solution salinized with NaCl + 50% K, 6.5 dS m-1; and S4 - nutrient solution salinized with NaCl + 100% K, 7.5 dS m-1). Yield (average fruit weight, production, fruit diameter, internal cavity, and pulp thickness), quality (pulp firmness, total sugars, soluble solids [SS], vitamin C, pH, titratable acidity [TA] and SS/TA ratio) and nutritional (K, Na and K/Na ratio) variables were evaluated. Plants fertigated with standard nutrient solution showed the highest values for fruit weight (1,190.6 g), production (2,381.3 g per plant), fruit diameter (13.6 cm) and pulp thickness (2.6 cm). Cultivar McLaren produced heavier fruits (931.4 g) with larger diameter (12.4 cm) and pulp thickness (2.4 cm). The addition of NaCl to nutrient solution induced a reduction in the yield variables but did not influence fruit quality. The addition of extra K to salinized nutrient solution did not mitigate the deleterious effect of salinity on the yield of melon.

Irrigation with brackish water reduces watermelon yield in the Brazilian semiarid region, requiring the establishment of management strategies that reduce the negative impacts caused by salt stress. The objective of this study was to evaluate the morphophysiology and concentration of inorganic solutes in watermelon crops subjected to different electrical conductivities of the irrigation water, using hardened seedlings or direct sowing. The experiment was conducted in the Baixo Acarau Irrigated Perimeter, in the state of Ceara, Brazil. A randomized complete block design was used, with split plots and four replications. The plots consisted of four electrical conductivity levels of the irrigation water (0.3, 1.5, 3.0, and 4.5 dS m-1), and the subplots consisted of three planting systems: DS = direct sowing; TP1 = transplanting of seedlings produced with moderate-salinity water (1.5 dS m-1), and TP2 = transplanting of seedlings produced with low-salinity water (0.3 dS m-1). The following variables were analyzed: vegetative growth, leaf gas exchange, and inorganic solutes. The use of watermelon seedlings produced with moderate-salinity water does not result in higher salt tolerance during the vegetative growth stage. Na+, Cl-, and Ca2+ leaf concentrations increase as the salt stress level is increased, regardless of the planting method. However, plants from seedlings (TP1 and TP2) have higher Na+ and Cl- concentrations when subjected to high salinity levels. The direct sowing method resulted in better performance of growth variables, mainly under low salinity levels.
