This research work aims to determine the level of maximum tolerance to salinity in the irrigation water of the spinach crop, without affecting its yield and quality. To determine this level of salinity, physical tests were performed (fresh weight, dry weight, size of the plant and roots); likewise, chemical tests to measure the concentration of foliar elements, soil salinity and water. The experimental phase in the field was 70 days, the plant growth cycle. The seeds were germinated in storehouses, and then transplanted into pots with sandy soil. 12 treatments were applied to the plants with water of different salinity levels, according to the water needs of the crop: 0.76 (T1); 1.3 (T2), 2.2 (T3); 3.5 (T4); 4.6 (T5); 5.7 (T6); 7.1 (T7); 8.5 (T8); 10 (T9); 12 (T10); 15 (T11) and 20 (T12) dS.m-1. For each treatment three repetitions were made, using a total of 36 pots. After the experimental period, the results of the tests determined that the plants with the highest growth (fresh weight and height) were those that were irrigated with the T1 treatment (0.76 dS.m-1), while it was observed that in the treatments with a higher level of salinity, the yield decreased. As for the absorption of elements, potassium, calcium, magnesium and sulfates show a higher concentration in the T3 treatment (2.2 dS.m-1). The concentration of chlorine and sodium increase as the concentration increases salinity of irrigation water. The crop did not show significant damage by any treatment, only a decrease in its yield caused by the increase in salinity levels was observed.
