Different Levels and Frequencies of Carrageenan Application on the Growth and Yield of Snap Beans (Phaseolus vulgaris) Under San Gabriel, La Union Conditions. Master of Science in Agronomy. Don Mariano Marcos Memorial State University, North La Union Campus, College of Graduate Studies, Bacnotan, La Union. Adviser: Analyn V. Sagun, Ph.D. Carageenan has been identified as a potential foliar fertilizer for crop cultivation. Hence, the study aimed to investigate the effects of various levels of Carageenan (L1: 1.6ml/16L water, L2: 180ml/16L water, L3: 200ml/16L water), different frequencies of application (F1: once a week, F2: every two weeks, F3: every three weeks after germination), the interaction between levels and frequencies of application, and the economic feasibility of using carrageenan for snap bean production. The research was conducted at Sitio Pulicay, Barangay Lipay Sur, San Gabriel, La Union from February to May 2022. Results of the study revealed that the performance of snap beans was not significantly influenced by the levels and frequencies of carrageenan foliar fertilizer. Moreover, the interaction between the different levels and frequencies of carrageenan fertilizer demonstrated comparable effects on the various parameters tested in snap bean cultivation.Thesis
