| ABSTRACT The underground water reserves in the semi-arid region present high salinity levels. However, the scarcity of the resource compels the use of this water for several human activities, including agriculture. The aim of this work was to evaluate the use of brackish water for watercress cultivation (Nasturtium officinale) in a hydroponic NFT system (laminar flow of nutrients) and effects on water consumption, growth, yield and nutrient extraction by the plant. We studied six levels of salinity (0.2; 1.2; 2.2; 3.2; 4.2 and 5.2 dS m-1), in a completely randomized experimental design, with four replicates. Salinity was obtained by the addition of NaCl into the local water supply, being these waters used to prepare the nutrient solution and to replace the... |

| Resumo:O objetivo deste trabalho foi avaliar o desempenho produtivo do agrião d'água (Rorippa nasturtium-aquaticum) cultivado em solo sob diferentes telas de sombreamento e a pleno sol, em dois ciclos consecutivos (muda e rebrota). Os tratamentos consistiram do cultivo do agrião d'água sob telas de sombreamento preta 35%, prata 35%, vermelha 35%, branca/prata 20% e a pleno sol (controle), em delineamento de blocos ao acaso com quatro repetições. No primeiro ciclo de desenvolvimento do agrião d'água, houve incremento de até 59% na produção de massa fresca sob sombreamento. A massa fresca proveniente da rebrota do agrião d'água variou de 419 g m-2, a pleno sol, a 3.027,7 g m-2 sob a tela prata 35%. Houve incremento do tamanho das folhas e da altura do dossel... |

| ABSTRACT In view of the limitations on good quality water, the use of low-quality water in agriculture is seen as a suitable alternative. The aim of this study was to evaluate, in a protected environment, the production of broadleaf watercress in an NFT (Nutrient Film Technique) hydroponic system as a function of the use of brackish water and different circulation times for the nutrient solution. The experiment was carried out in the experimental area of UFC, in Fortaleza, Ceará, from December 2018 to March 2019 (two crop cycles). The treatments were distributed in a randomised block design in a 5 x 2 factorial scheme, five levels of water salinity (0.6, 1.6, 2.6, 3.6 and 4.6 dS m-1) and two circulation times for the nutrient solution (10 and 15 min),... |
