Abstract

Abstract:

Selenium deficiency is a common issue in China’s arable land. This study aimed to evaluate the effects of different concentrations of aminopolysaccharide selenium water-soluble fertilizer (ASe) and organic selenium-rich phytonutrient (ZSe) on the growth performance and selenium fortification of quinoa greens (Chenopodium quinoa ‘Huai quinoa 1’). Different concentrations of ASe and ZSe were applied via foliar spraying to assess their impact on the growth and nutritional composition of quinoa greens. The results showed that under the 4.50 L/hm² ASe treatment, the fresh weight, dry weight and yield of quinoa greens reached their maximum, with yield increasing by 23.46% compared to the control (CK). Appropriate concentrations of selenium significantly enhanced the relative chlorophyll content as well as the total nitrogen, phosphorus, and potassium levels. Foliar application of exogenous selenium significantly increased the soluble sugar, protein, and selenium content in quinoa greens, although nitrate levels also rose. Fuzzy membership function analysis indicated that an ASe concentration of 3.75 L/hm² had the best overall effect on improving the quality of quinoa greens. In conclusion, applying appropriate concentration of ASe could significantly enhance the growth performance, quality, and selenium fortification of quinoa greens, offering great potential for widespread application.

Key words: quinoa greens, aminopolysaccharide selenium, water-soluble fertilizer, functional agriculture, yield
