This study aimed to evaluate the growth and yield performance of pechay (Brassica rapa var. parachinensis) using different animal manures under field conditions in Calanasan, Apayao. The experiment followed a Randomized Complete Block Design (RCBD) with four treatments: T0 (control: soil and carbonized rice hull), T1 (chicken manure), T2 (cow manure), and T3 (sheep manure). Growth parameters such as plant height, number of leaves, leaf length, and root length were measured every five days, while yield was determined at harvest. Results revealed that T3 consistently produced the highest growth and yield, followed by T2, T1, and T0. Analysis of Variance (ANOVA) indicated significant differences among treatments. The findings suggest that sheep manure is the most effective organic fertilizer for enhancing pechay production and can serve as a sustainable alternative to chemical fertilizers for local farmers.
