Vegetal mulching can mitigate the harmful effects of salts present in irrigation water. This study aimed to evaluate the effect of irrigation water salinity and mulching on the growth and yield of beet crops. The experiment was conducted in a greenhouse at Redenção, Ceará State. The experimental design was completely randomized in a 2 × 4 factorial scheme, with five replicates, composed of two levels of electrical conductivity of irrigation water - ECw: tap water - 0.3 dS m-1 and saline solution - 5.8 dS m-1; and four types of mulching (rice hulls, carnauba bagana, crop residues, and a control treatment without soil cover). The use of vegetal mulching, mitigated the effects of irrigation with saline water on the variables plant height, leaf area, stem diameter, and tuberous root. The increase of the salt concentration in irrigation water negatively affected the number of leaves, length of the tuberous root, and yield. But, it increased the soluble solids in the beet crop.
Salt stress negatively affects the sense, the objective of this work was to evaluate growth and soil saturation extract parameters (EC and pH) in cowpea crop irrigated with saline water under different leaching fractions. The experiment was conducted in the experimental area of the Auroras Seedling Production Unit, which belongs to the Universidade da Integração Internacional da Lusofonia Afro used was entirely randomized, in a 5x2 factorial scheme, referring to five 15 and 20%) and two electrical conductivities of the irrigation water (0.3 and 4.0 dS m repetitions. The leaf area, aboveground and root dry mass were negatively affected with the increase of the leaching fraction, however, with less intensity with water of lower salinity. Increasing the leaching fraction increased the number of leaves, stem diameter, and pH, but more efficiently with the lower salinity water. The increase of the leaching fraction associated with increased the electrical conductivity of the
