Abstract
This study focus on the assessment of mineral and organic fertilization on WF in a fertirrigated melon crop under semiarid conditions with a low water quality. During successive years, a melon crop (Cucumis melo L.) was grown under field conditions. Different doses of ammonium nitrate were used as well as waste compost derived from the wine-distillery industry, which is relevant in this area. Grey WF was estimated in both type of fertilizers using Castellanos et al. [3] methodology. The results showed that in the case of inorganic fertilization gray WF experiment a huge increase when the optimum dose were exceeded. Meanwhile, in the case of organic fertilization, even the doses exceeded the optimum, the increase gray WF was significantly lower. The discussion of these results will be presented based on the mineralization rate and N content of irrigation water.
