Abstract:
The study was conducted to evaluate the phytochemical properties of Pechay applied with different types and levels of organic and inorganic fertilizers under different methods of application. In particular, the study aimed to determine the phytochemical components of Pechay using different nutrient sources and application methods and compute its Return on Investment (ROI). Randomized complete block design (RCBD) was used with three replications conducted at Mindanao State University-Main Campus, Marawi City. Results of the study revealed that all three replications of T2 plants showed double positive (++) in tannins while T5 plants revealed double positive (++) in flavonoids indicating that both T2 and T5 plants are having harmful levels of the phytochemicals. The results showed that all other treatments are safe from harmful phytochemical components. Based on the results of the study, considering that T2 (Rec. Rate (RR) Inorganic Fertilizer) and T5 (50% RR Inorganic Fertilizer + 50% RR Organic Fertilizer) treated plants are high in tannins and flavonoids respectively, it is therefore safe to recommend the use of T6 (50% RR Inorganic Fertilizer + 50% RR Foliar Fertilizer), T3 (RR Organic Fertilizer) and T4 (RR Foliar Fertilizer) whatever is affordable and locally available to the farmers. In areas where land area is a problem, this study showed that the use of pots can be a viable alternative to increase production and provide food in urban settings.
