Resumo: | Irregularity or shortage of rainfall in semi-arid regions forces farmers to use low-quality water to irrigate crops. The present study aimed to assess the water-use efficiency and post-harvest quality of ‘Sugar Baby’ mini watermelon in response to different electrical conductivities of the nutrient solution [2.5 (control), 3.5, 4.5, 5.5 and 6.5 dS m-1], in a floating hydroponic system. The experimental design was completely randomized, with four replicates. The water consumption, production and water-use efficiency were evaluated, as well as qualitative and physico-chemical variables of the fruits. The total water consumption of the plants during the crop cycle varied between 43 (6.5 dS m-1) and 54 (2.5 dS m-1) L plant-1 among the treatments, with water-use efficiency of 0.031 kg L-1. The greatest reductions due to the nutrient solution salinity were observed for the rind thickness and fruit mass (8.80 and 5.69 %, respectively, per unit increase in dS m-1). The salinity of the nutrient solution did not influence the soluble solids content and fruit maturity index, but it had a negative effect on the pH and titratable acidity.

Objetivou-se avaliar a eficiência do uso de água e qualidade pós-colheita de minimelancia ‘Sugar Baby’, em resposta a diferentes condutividades elétricas da solução nutritiva [2,5 (controle); 3,5; 4,5; 5,5; e 6,5 dS m-1], em sistema hidropônico floating. O delineamento experimental foi o inteiramente casualizado, com quatro repetições. Avaliaram-se o consumo hídrico, produção, eficiência do uso de água e variáveis qualitativas e físico-químicas dos frutos. O consumo hídrico total das plantas durante o ciclo variou entre 43 (6,5 dS m-1) e 54 (2,5 dS m-1) L planta-1 entre os tratamentos, com eficiência do uso de água de 0,031 kg L-1. As maiores reduções pela salinidade da solução nutritiva foram observadas para espessura da casca e massa dos frutos (8,80 e 5,69 %, respectivamente, por incremento unitário em dS m-1). A salinidade da solução nutritiva não influenciou o teor de sólidos solúveis e índice de maturação dos frutos, porém teve efeito negativo sobre o pH e a acidez titulável.
