The negative water balance in the Canary Islands makes it nessesary to recycle for agriculturalñ treated wastewater. This paper studies the absorption by the plant of the N content of the treated wastewater and the effect on yiels in comparison with mineral fertilizers dissolved in distilled water in a quantity equivalent to the content of the water under study. In the conditions of our assay and taking into account greater irrigation dose, the yield results as dry matter weight and $ N absorbed by the plants, never were significatively lower than those obtained with equivalent dose of mineral fertilizers though the N concentration in the treated wastewater were not sufficient to provide enough N to the culture.
