Comparison of Agronomic Parameters and Nutritional Composition on Red and Green Amaranth Species Grown in Open Field Versus Greenhouse Environment

Previously, researchers have not paid attention to indigenous African leafy vegetables such as nightshade and kale, however, amaranth species recently gained popularity due their adaptability various climatic conditions cultivation in both open fields hydroponics. Amaranth are ranked among the underutilized with medicinal properties, economic values, nutritional health benefits. This study aimed compare growth parameters composition of two consumed red (Amaranthus Cruentus L.) green Graecizans South Africa, cultivated an field versus a greenhouse. The findings showed high chlorophyll content large leaf area under on species. number leaves stem height were higher greenhouse system. In cultivation, minerals calcium, magnesium, phosphorus, iron, zinc, aluminium, copper manganese for significantly whilst potassium, sodium, boron, sulphur production. sufficient total nitrogen ash recorded production, no significant difference was observed between moisture A. Cruentus. conclusion, Graecizansn grown had proximate mineral over
