The study evaluates the yield response of pechay to the different rates and combination of inorganic fertilizer and sea crop liquid fertilizer and the effects on some agronomic characteristics of pechay. The findings show that the use of sea crop liquid fertilizer in addition to inorganic fertilizer increased crop yield and income in pechay. Agronomic parameters such as plant height, number of leaves and length of leaves are observed to be highest when the sea crop liquid fertilizer is applied.
