Expression of bioactive compounds in different pepper cultivars (Capsicum annuum L.) in response to different fertilizer treatments

This research aimed at evaluating four cultivars of Capsicum annuum L. with different nutrient sources to ascertain the source that would improve soil characteristic and promote accumulation carotenoids flavonoids in peppers. Four sources: poultry manure, pig goat nitrogen: phosphorus: potassium (NPK) were used for study. The experiment was conducted as a 4 × 5 Factorial Complete Randomized Design (CRD) Botanical Garden University Nigeria, Nsukka. soils features analyzed by standard methods. fruits biochemical content quantified aid High-Performance Liquid Chromatography National Research Institute Chemical Technology, Zaria, Nigeria. α-carotene level (333.48±0.27 mg/L) highest “Nsukka yellow pepper” grown on mixed manure while β-carotene (45.56±0.29 when manure. “Tatase” cv. planted expressed fruit capsanthin lutein highly In conclusion, growing could increase production α-carotene, will β-carotene.   Key words: Biochemical, inorganic fertilizer, micronutrient deficiency, organic pepper.
