The study was conducted at Manuel Roxas, Sto. Nino, South Cotabato to: 1) to evaluate the effect of palm oil mill effluent on pechay; 2) determine the best level of POME for pechay and; 3) evaluate the economics of using POME in the production of pechay. Six application rates as treatments were studied using a Randomized Complete Block Design replicated 3 times. Results of the study showed that POME influenced the growth and yield of pechay. Application of 7.2 li POME/10 sq m obtained the highest yield of 45.44 t/ha, similar to the yield of pechay applied with the recommended rate of inorganic fertilizer (42.5 t/ha). Other agronomic parameters such as plant height, number of leaves, length of leaves, width of leaves, and dry matter yield were observed highest when applied with the same rate of POME which were similar to pechay applied with the recommended rate of inorganic fertilizer. Highest net income and return on investment (ROI) was obtained from pechay with the same POME application. The above findings reveal that the application of 7.2 li POME/ sq m can substitute for inorganic fertilizer to increase the yield of pechay.
