This study aimed to determine the variability properties of four major types Amaranthus species in protein and amino acids content leaves flowers. Obtained results by ion exchange chromatography our have shown high values for essential lysine methionine. In leaf, ranged from 3.9 (A. caudatus) 7.0 cruentus; A. moleros), flowers 4.2 6.7 molleros). The methionine 3.1 7.4 mantegazzianus) leaf flowe...

The present work compared the agronomic traits, chemical composition, fatty acid profile, and in vitro fermentation characteristics of twelve accessions Amaranthus spp., belonging to A. cruentus, hybridus, hypochondriacus, tricolor, grown a semiarid Mediterranean area. Among accessions, Benin Arizona (A. cruentus) Pennsylvania hypochondriacus) showed highest seed yield (on average, 322.1 g m−2)...

Due to an increasing demand of leaf vegetables, and hence their economic importance in the tropics, it is very common that excessive fertilizer N rates are applied to vegetable gardens and fields to attain high yield. This calls for more information on their nutrient requirements. In this study, we designed experiments to explore the effect of organic N levels on the yield and agronomic N use e...
