(2023). Methods of Planting Different Hybrid Glutinous Corn Under 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: Libunao, Virgilio M., Ph.D. The unusual evidence of transplanting in corn cultivation in the Philippines triggered the researcher to test its feasibility on a farm scale. Thus, this study was designed to assess the performance, profitability, and interaction effects of planting methods (direct seeding and transplanting) on three hybrid glutinous corn varieties (Purple Sweet, Violeta, and Honey Purple) grown in La Union. The study employed a strip plot design composed of three blocks. The two different planting methods were the vertical factors, while the three hybrid glutinous corn varieties were the horizontal factors. From January to April 2021, this research was carried out in Damortis, Santo Tomas, La Union. The two methods of planting proved to have significant influenced on the performance of hybrid glutinous corn varieties. Highly significant variations were observed on the day after sowing to seedling emergence, while significant results were noticed on seedling survival, days after sowing to silk initiation, and days after sowing to harvesting. The three hybrid glutinous corn varieties revealed highly significant on plant height, days after sowing to silk initiation, days after sowing to harvesting, ear diameter, and number of developed kernels. whereas on the parameters percentage of corn produced tillers, number of tillers per plant, number of leaves of the main stem including tillers, number of ears, cob diameter, and dry weight of upper biomass, significant differences were noted. All parameters evaluated observed no interaction variation.Item Types of rearing system and kinds of litter material for broilers(Don Mariano Marcos Memorial State University- North La Union Campus, 2023-05) Orteza, Jay O.ORTEZA, JAY OCASION.

(2023) Survival Percentage and Growth of Three Fruiting Varieties of Mulberry (Morus alba. L) as Influenced by Different Duration of Rooting Hormone. Master of Science in Agronomy. Don Mariano Marcos Memorial State University, North La Union Campus, College of Graduate Studies, Bacnotan, La Union. Adviser: Sagun, Analyn V., Ph.D. Generally fruiting mulberry varieties are difficult to multiply by vegetative means. However, it may be facilitated through the use of hormones. This study was conducted to find out the most responsive mulberry varieties (V1-Alf025, V2-Alfonso, and V3-Alf004), find out the best dipping duration (L1-36hrs, L2-24hrs, and L3-12hrs), determine the interaction effect of the dipping duration and mulberry fruiting varieties on the survival percentage and growth and determine the economic potentials of hormone dipping with the different mulberry varieties. Two thousand one hundred sixty (2,160) mulberry cuttings were randomly distributed into two factors with three replication employing strip plot design. Results showed that the duration of hormone dipping significantly affected the survival rate and growth of the mulberry fruit variety. The three mulberry fruiting varieties performed comparably except for the weight of the shoot and length of the roots. Further, the interaction of the dipping duration of hormones and the variety of mulberry significantly influenced the survival rate and growth.Item Response of different varieties of hybrid rice (Oryza sativa L. indica.) to different levels of foliar fertilizer under barangay Casiaman, Bacnotan, La Union conditions (DS 2022)(Don Mariano Marcos Memorial State University- North La Union Campus, 2023-05) Camat, Mary Dulce V.CAMAT, MARY DULCE V.
