Abstract:

This study aimed to determine how different amounts of Fish Amino Acid (FAA) affected the growth, yield, and profitability of Yellow Corn (Zea mays L.). The experiment was conducted at the Integrated Farming Production Center in Langtad, Indanan, Sulu, Philippines, at Mindanao State University - Sulu, College of Agri- culture, from June 21 to September 25, 2023. Four treatments were analyzed in this research: 350 ml of FAA, 300 ml of FAA, and 250 ml FAA with a control group (without treatment) using Ran- domized Complete Block Design (RCBD) consisting of three repli- cations. In this case, the FAA was produced from sardine waste with molasses (at a ratio of 1:1) and used in foliar spraying every second week. Measurements of growth included plant height, leaf number and length (table 4), while yield measurements included ear length (with and without husk), total number and weight per unit area for harvested ears, as well as return on investment (ROI). The results showed that corn treated with 350 ml FAA (T1) produced the tallest plants (124.39 cm at the 2nd month), longest leaves (79.40 cm at the 2nd month), most ears (145.67), heaviest harvested weight (16.28 kg) and ROI (487.52%). Although there was no statistically significant difference in plant height, leaf length and ear length between FAA application group and control group (P>0.05), the weight of ear harvested after maize harvest was significantly improved with treatment of FAA while a signifi- cant number of ears were as well produced per unit area (P<0.01). Compared to the FAA and control, lower growth, yield, and profit were shown for FAA levels. In conclusion, the study found that FAA, a nutritious source of nitrogen and other necessary nutrients, can be an effective organic fertilizer for corn production with minimal environmental impact. *Corresponding author: E-mail: muksidal.hasim@msusulu.edu.ph Hasim et al., 2026 / Effect of Varying Levels of Fish Amino Acid on the Growth and Yield of Yellow Corn in Sulu, Philippines IJMABER 1496 Volume 7 | Number 4 | April | 2026 For optimal growth, yield, and economic return, each plot should receive a sufficient amount of FAA, specifically 300 to 350 ml. The ongoing research initiatives may range from to further replications, open experimental plots, pest and diseases monitor- ing as well as testing the applications of FAA varieties in other high valued crops commodities.
