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.
