Effects of salinity on the nutritional quality of amaranth (Amaranthus cruentus) leaves: Case of local and resistant varieties

Climate change is a real obstacle to agriculture because of the difficulty water supply. Farmers are trying mitigate this problem by developing several strategies including those based on irrigation. Unfortunately, these irrigation techniques favour entry sodium in food crops. In response situation, research has been conducted Benin develop salinity resistant variety local amaranth (called line 23). The objective study determine nutritional values grown under salt stress and compare them with same conditions. Local plants were environment then stressed concentrations 0; 7.1 19.6 mmol NaCl. After harvesting, leaves sent laboratories for determination elements. Three replicates done. Analysis variance was used means elements assayed using JMP software (SAS Institute MC 2007). results show significant improvement calcium, phosphorus, potassium vitamin A levels 23 contrast reference cultivar. However, content, although decreasing as concentration increases, remains above acceptable limits. As cultivar, an increase elements: iron, magnesium, that sodium, which harmful cardiovascular health.
