This research was carried out in Purok 1, Barangay Arenas, Arayat, Pampanga. The Two-way analysis Factorial Split-Plot Design was employed in this study as the research design. Factor A (Main treatment) is the shading condition (Shaded, 50°o Shading Intensity non-shaded), and factor B (Sub-treatment) is the pre-treatment. The treatments to be used. Golden Shower (Cassia fistula L.) seeds were the experimental plants, and they were treated to the study's numerous treatments. One thousand four hundred forty (1,440) Golden Shower (Cassia fistula L.) seeds were collected in front of the Department of Animal Science at the Pampanga State Agricultural University. Based on the results of this study, 50 percent shade is the ideal shading intensity in the early growth of golden shower seeds. Furthermore, 50 percent shading is recommended to limit the influence of extreme heat on the growth of golden shower seedlings. Sunrays are somewhat filtered during the first generation of the golden shower. The best treatment for Golden Shower seed germination is nicking. Germination of Golden Shower A1B3 (Shaded, Nicking) had the highest average in Germination Percentage, Germination Capacity, and Germination Energy. A2B2 (Partially Shaded, Tap Water) had the highest average for the Energy Period. The number of leaves, plant height, and plant diameter were all collected in the initial data collection. According to the statistics, golden shower plants improved in all metrics from Day 0 to Day 30.
