[Unpublished thesis, Don Mariano Marcos Memorial State University - North La Union Campus, Sapilang, Bacnotan, La Union]. Lakasa ti Sirib, DMMMSU Institutional Repository.https://lakasa.dmmmsu.edu.ph/handle/123456789/1640This study was designed primarily to: 1) determine the performance of liquid fertilizer on the growth and yield of bush sitao in terms of: (a) mean height, (b) mean number of leaves, (c) mean number of pods, and 2) to determine the effect of the formulated organic fertilizer on the nutrient composition of soil in terms of: (a) nitrogen, (b) phosphorus, (c) potassium. The following treatments were used: T0 – tapwater (control) T1 – 40 L tapwater + 100 ml brown algae extract + 100 ml ipil-ipil leaves extract + 20 tbs. ash + 50 ml. biosol T2 – 40 L DPERF wastewater + 100 ml brown algae extract + 100 ml ipil-ipil leaves extract + 20 tbs. ash + 50 ml. biosol T3 – 40 L SRDI wastewater + 100 ml brown algae extract + 100 ml ipil-ipil leaves extract + 20 tbs. ash + 50 ml. biosol T4 – 40 L Fish Washing + 100 ml brwon algae extract + 100 ml Ipil-Ipil leaves extract + 20 tbs. ash + 50 ml. biosol The five treatments were replicated three times. Analysis of variance (ANOVA), Tukey HSD Multiple Comparison and T-Test were used in the analysis and interpretation of data. Result showed that there is a significant variation in the height of the bush sitao when irrigated by different treatments using both newly formulated and fermented organic liquid fertilizer; mean number of leaves varied significantly using the different treatments in newly formulated and fermented organic fertilizer; mean number of pods of bush sitao varied significantly using the different treatments; and the nutrient analysis of soil was found out to have changed before and after the application of varying treatments from newly formulated and fermented organic liquid fertilizer.en-USThesis
