From: Nitrogen physiology of contrasting genotypes of Chenopodium quinoa Willd. (Amaranthaceae)

Phenotype, Yield, Nitrogen Use Efficiency (NUE) and Harvest Index (HI) of three genotypes of C. quinoa growing under different Nitrogen supplies. (a) Four-month-old Faro (top), UdeC9 (middle) and BO78 (botton) were grown at High Nitrogen (HN) and Low Nitrogen (LN) supplies. Photographs were taken two weeks after flowering. (b) Yield (c) NUE (d) HI. Bars show Mean values ± SE (n = 4). Different letters represent significant differences among genotypes and treatments at P < 0.05 using two-way ANOVA.
