ABSTRACT:
Objective: To evaluate a quinoa (Chenopodium quinoa Willd.) cultivar in a semi-hydroponic system, simulating different levels of sulphatic salinity (CaSO4·2H2O to 0, 3 000, 4 000 and 5 000 ?S cm?1). Design/methodology/approach: The cultivation of quinoa established in a semi-hydroponic system, simulating different conditions of sulphatic salinity, taking as a source of salinity reactive grade dihydrated calcium sulphate (CaSO4 2H2O), this salinity source is obtained to simulate the conditions of the evaporitic basin of Río Verde-Matehuala, San Luis Potosí, Mexico where a saline diversity of waters and soils mainly calcium sulphate is formed. The reactions were 0, 3,000, 4,000 and 5,000 ?S cm?1, being that null in salts, the treatment control. Results: The seed yield per plant in sulfate salts treatments were for 3,000 ?S cm?1 with 30.65 g plant?1, following the treatments of 4,000 ?S cm?1 with 23.31 g plant?1 and 5,000 ?S cm?1 with 19.13 g plant?1; on the other hand, the control resulted in the highest value in yield with 43.41 g plant?1. Limitations on study/implications: It is important to develop more studies under biotic and abiotic conditions that occur in other regions and test another type of salinity such as hydrochloric. Findings/conclusions: Under the conditions in which the study will be affected, it is possible to grow quinoa in sulphate soils, but with the restrictions imposed by the effect of the decrease in osmotic potential damaged by salts.
