Abstract: Due to the low supply and high demand for garlic in the Philippines, sudden price spikes occur to the detriment of consumers since garlic is a major condiment used in the households. The average yield per hectare in the country is significantly lower than in other countries, hence, there is an urgent need to improve the growth and yield of garlic through the use of plant performance enhancer like paclobutrazol. The study was conducted to evaluate the effect of different concentrations of paclobutrazol (PBZ) on the growth and yield performance of garlic (Allium sativum L.), with the the different rates of paclobutrazol application on native garlic was conducted from February 8, 2025 to May 17, 2025 at Sinapangan, San Juan, La Union, Philippines. Results revealed that paclobutrazol significantly influenced the agronomic and economic performance of garlic. Among the treatments, the application of 10 ml paclobutrazol per liter of water produced the highest yield, gross inome, net income and return on investment. These findings indicate that paclobutrazol at this concentration was the most effective in improving both yield and economic returns in garlic production. Further studies are recommended to explore the response of other garlic varieties to PBZ application.
