The source and quantity of nutrients available to plants can affect the quality of leafy herbs. A
study was conducted to compare quality of Cosmos caudatus in response to rates of organic
and mineral-based fertilizers. Organic based fertilizer GOBI (8% N: 8% P2O5: 8% K2O) and
inorganic fertilizer (15% N, 15% P2O5, 15% K2O) were evaluated based on N element rates
at 0, 30, 60, 90, 120 kg h− 1. Application of organic based fertilizer reduced nitrate, improved
vitamin C, antioxidant activity as well as nitrogen and calcium nutrients content. Antioxidant …
