Adviser: Sagun, Analyn V., Ph.D. Different varieties of hybrid rice and different levels of foliar fertilizers are important factors in crop growth and yield. Hence, this study was conducted with the objectives of determining the performance of three hybrid rice varieties, determine the effects of different levels of foliar fertilizer applied to hybrid rice, find out the interaction effects of hybrid rice varieties and levels of foliar fertilizers on the growth and yield of rice, and determine correlation of various parameters. This study was conducted from September 9, 2022 to January 17, 2023 at Barangay Casiaman, Bacnotan, La Union. The results revealed that the best variety was SL20H and 16 table spoon/ 16L of H20 + 75% BSR was the best level of foliar fertilizer. The interaction of different varieties of hybrid rice and different levels of foliar fertilizer were highly significant on the mean fresh weight of grains. Highly significant relationship between number of tillers versus filled grains but no significant correlation between length of panicle versus grain yield (fresh and dry weight) was noted.Thesis
