| ABSTRACT The need to use strategies for using brackish water in agriculture, especially in semi-arid conditions, is evident. Based on this information, this study was developed with the aim of evaluating the consumption, efficiency and water content, as well as the dry mass of the arugula plants (cv. Broad Leaf) exposed to brackish nutrient solutions as a function of replacement strategies and circulation frequencies. The treatments consisted of six salinity levels of the nutrient solution (1.5, 3.0, 4.5, 6.0, 7.5 and 9.0 dS m-1) and two circulation frequencies (twice a day 8 a.m. and 4 p.m., and three times a day at 8 a.m., 12 p.m. and 5 p.m.). In Experiment I, the evapotranspiration line was replaced with the respective brackish water used in the... |

| ABSTRACT The analysis of plant response to the cationic variability of the waters, in addition to the osmotic component, is indispensable in the context of salt stress. Thus, between October 2017 and February 2018, in Recife, PE, Brazil (8° 1’ 7” S and 34° 56’ 53” W, and altitude of 6.5 m), the present study was carried out to evaluate the water relations of parsley plants (Petroselinum crispum), cv. Graúda Portuguesa, cultivated in brackish nutrient solutions (electrical conductivities of 1.7, 2.7, 3.7, 4.7, 5.7 and 6.7 dS m-1) prepared in waters with different cationic natures (NaCl, CaCl2, KCl and MgCl2). The experimental design was completely randomized, in a 6 x 4 factorial scheme, with five repetitions, and five plants per plot. Two experiments were... |
