| ABSTRACT A large number of studies on salinity in hydroponic systems have been carried out, but few of them have evaluated the interaction between salinity and nutrient solution temperatures. Two experiments were carried out in a randomized block design from January to February (Experiment I) and June to July 2018 (Experiment II). Experiment I consisted of treatments with five combinations, as follows: unheated (control) and heated nutrient solution (NS) at a temperature of 32°C using fresh water with an electrical conductivity (ECw) of 0.3 dS m−1, and unheated and heated NS at temperatures of 30 and 32°C using brackish water with an ECw of 6.5 dS m−1 in the main plots, with two coriander cultivars (Tabocas and Verdão) in the subplots, which were grown in... |

| ABSTRACT The present study used a hydroponic system with leveled channels, in order to evaluate coriander cultivation under different intervals of nutrient solution recirculation and the use of freshwater and brackish water. The experiment was carried out in a randomized block design with five replicates, in a 2 x 4 factorial scheme, from February to March 2014. Two levels of electrical conductivity (EC) of water (0.32 and 4.91 dS m-1) and four frequencies of nutrient solution recirculation (at intervals of 0.25, 2, 4 and 8 h) were evaluated. This experimental design was adopted in the evaluations performed at 10, 15 and 25 days after transplantation (DAT). Additionally, at 21 DAT subplots were established for the evaluation of plant position (initial,... |

| ABSTRACT An experiment was carried out in an adapted DFT (deep film technique) hydroponic system in PVC pipes to evaluate the growth, production and water consumption of coriander cv. ‘Verdão’, during June-July 2014. The experiment was carried out in a randomized block design with five replicates, in a 2 x 4 factorial scheme, totaling 40 plots. Two intervals of nutrient solution recirculation (0.25 and 2 h) and four levels of water electrical conductivity (ECw 0.26, 2.47, 4.91 and 7.0 dS m-1) were evaluated. At 25 days after transplanting (DAT), the reductions in plant height and in the shoot fresh and dry matter of the bunch were 2.95, 6.08 and 3.32% per unit increase of ECw (in dS m-1). Despite the reductions in growth and production, saline stress did... |
