In desalination process, besides the potable water, highly salty and pollutant water (brine) is generated, which can be used for producing crops since it is carefully monitored. In order to test this hypothesis, bell pepper plants, cv. 'Margarita', were grown in coconut fiber substrate under greenhouse and were irrigated with nutrient solutions prepared with tap water, brine from desalination plant, and its dilution with tap water at 75, 50 and 25%, giving a range of electrical conductivities of the nutrient solution (ECs) of 2.6, 3.1, 6.6, 10.0 and 12.2 dS m-1 after the dilutions and fertilizers addition. Completely randomized blocks design was used with 5 treatments (salinity levels of the nutrient solutions) and six replications. Leaf area, number of marketable fruit, total and marketable yield were reduced with ECs increase. The marketable yield of bell pepper 'Margarita' reduced 6.3% for each unitary increase of ECs above 2.6 dS m-1 (threshold salinity) and the results suggest that in hydroponic system, the reduction of marketable yield with increasing ECs is promoted by reduction of the number of fruits per plant instead of a reduction of fruit mean weight.

RESUMEN: Se usaron técnicas de análisis estadístico multivariado, para determinar la variación temporal y espacial de la calidad del agua en la zona costera de Santa Marta, donde se ubica un emisario submarino que descarga 1 m3/s de aguas residuales domésticas. La ANOVA de dos vías, los análisis de clúster y de componentes principales mas la interpolación de krigging, fueron considerados para este análisis. En la variación temporal se encontraron diferencias que marcan en el año dos periodos de tiempos heterogéneos, de diciembre a abril la concentración de los parámetros de calidad del agua es más alta. El resto del año (mayo, junio, agosto, noviembre, exceptuando el mes de julio donde se presentaron concentraciones altas), se registran concentraciones sensiblemente inferiores. En la variación espacial se reportan dos grupos de áreas en las cuales la calidad del agua es diferente, dicha diferencia está relacionada con la cercanía a la descarga del emisario submarino. | ABSTARCT: Multivariate statistical techniques were used to investigate the temporal and spatial variations of water quality at the Santa Marta coastal area where a submarine outfall that discharges 1 m3/s of domestic wastewater is located. Two-way analysis of variance (ANOVA), cluster and principal component analysis and Krigging interpolation were considered for this report. Temporal variation showed two heterogeneous periods. From December to April, and July, where the concentration of the water quality parameters is higher; the rest of the year (May, June, August-November) were significantly lower. The spatial variation reported two areas where the water quality is different, this difference is related to the proximity to the submarine outfall discharge.
