Comparative analysis of phytochemical composition and return on investment in Pechay cultivated with organic and inorganic fertilization techniques

Abstract

This study, "Comparative Analysis of Phytochemical Composition and Return on Investment in Pechay Cultivated with Organic and Inorganic Fertilization Techniques," evaluates the effects of organic and inorganic fertilizers on the phytochemical profiles and economic outcomes of Pechay (Brassica napus L. subsp.chinensis var.Black Behi) cultivation.Through a controlled experimental design, the research assesses key phytochemical constituents-total phenolics, flavonoids, glucosinolates, vitamin C, and beta-carotene-alongside yield metrics and financial returns from organic and inorganic fertilizer applications.Results demonstrate that organic fertilization significantly boosts the phytochemical content of Pechay, suggesting enhanced nutritional benefits.Conversely, inorganic fertilization yields higher crop production but does not significantly improve phytochemical concentrations.Economically, despite the potentially lower yields, organic cultivation of Pechay presents a higher return on investment due to the premium market prices for organically grown produce and costeffectiveness of organic farming practices.This study underscores the dual benefits of organic farming in enhancing the nutritional quality of Pechay while ensuring better economic returns for farmers, advocating for a shift towards more sustainable and profitable agricultural practices.
