The objective of this study is to provide information on the influence of NPK fertilizer on the agronomic performance and antioxidant concentration of pumpkin leafy vegetable for the purpose of enhancing its cultivation and popularizing its utilization. The experiment was conducted in 2007 and 2008, at the Teaching and Research Farm, Obafemi Awolowo University, Ile-Ife, Nigeria. The experiment was a randomized complete block design with 3 replications. Compound fertilizer, NPK /15:15:15/ was used and added as ring dressing in four levels; 0, 90, 180, 270 kg/ ha-1. Data were recorded for several growth and leaf yield parameters. At the seventh week after planting, the harvested young leaves extracts were analyzed for antioxidant activities and antioxidant phenolic compounds concentration using different antioxidant assays. The significant highest estimates for vine length, leaves number, stem diameter, number of branches and number of tendrils per plant and total young leaf yield were resulted from plants treated with 180 and 270kg/ha-1. It is concluded that 180 kg/ha-1 of NPK fertilizer is required for optimal yield and antioxidant composition of pumpkin leafy vegetable.info:eu-repo/semantics/openAccessChilean Society of Soil Science / Sociedad Chilena de la Ciencia del SueloJournal of soil science and plant nutrition v.12 n.3 20122012-09-01text/htmlhttp://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0718-95162012000300001en10.4067/S0718-95162012005000001
