Characterization of Nutritional Potential of Amaranthus sp. Grain Production

Abstract

The growing demand for nutritious foods has spurred investigations into alternative sources of nutrition beyond traditional options. For this reason, the present study approaches amaranth, which is a plant with high nutritional potential. Based on the unique pedoclimatic conditions of the Somes meadow in Transylvania and the known adaptability of amaranth varieties to diverse environments, we hypothesize that certain amaranth varieties of South American origin will demonstrate their potential for morphological development, grain biomass yield, and quantitative characteristics when cultivated in this specific environment. Our study aims to identify if, based on morpho-productive traits, the six amaranth varieties under investigation in a specific environment are suitable for consumption as functional food. A bifactorial trial was implemented with the following factors: amaranth species and amaranth varieties. Two species and seven varieties of amaranth were studied. Differences are reported between morpho-productive and quantitative traits of the seven amaranth varieties studied in this research. The Pearson simple correlations show that morphological traits moderately contribute to grain fresh biomass yield, while morphological traits and fresh biomass strongly contributed to grains dry biomass yield. Our study shows that while current research offers valuable perspectives on the performance and nutritional composition of amaranth varieties studied, there are recommended more studies conducted across diverse environments.
