Effects of Goat Manure Fertilization on Grain Nutritional Value in Two Contrasting Quinoa (Chenopodium quinoa Willd.) Varieties Cultivated at High Altitudes

In this study, the effects of goat manure fertilization (2, 4, 8, and 12 Tn/ha) on grain yield, organic compounds, mineral composition two quinoa varieties (CICA-17 Regalona Baer) were evaluated under field conditions in Northwest Argentina. The results indicate that improved yield total protein content. Low doses positively affected fatty acid (FA) profile, significant changes determined for monounsaturated (MUFA) polyunsaturated (PUFA) contents CICA-17 saturated (SFA) R. Baer seeds. amino negatively Baer. Soluble sugars (glucose, fructose, sucrose), major elements (K, Si, P, Mg, Ca, Na), minor (Fe, Mn, Al, Zn, Cu), ultratrace (Cr Li) detected discussed terms their impact human nutrition health. Conclusively, addition some essential acids, desaturase activity, n6:n3 SFA/UFA ratios, atherogenic index, soluble sugars, content, metabolism each variety was differently affected, especially C16 C18 which responded to various doses. Manure is a promising alternative improve nutritional quality functionality grains, but response not linear.
