Abstract
In the Philippines, viticulture is an emerging profitable farm business with excellent
potential for extensive commercial production. Grapes have been popularly grown in the
province of La Union because of their high value and demand. This study aimed to assess
the grape production of La Union, document the existing management practices of grape
growers, and evaluate the fruit quality of grapes in La Union. The study was conducted at
the selected grape farms in La Union, while the testing of nutrient status, pH of the
collected soil samples, and sweetness of fruit from the selected grape farms were done at
Don Mariano Marcos Memorial State University, North La Union Campus, College of
Agriculture, Bacnotan, La Union.
A total of 30 grape growers from the municipalities of Bauang and Caba, La Union,
were selected as respondents. The findings revealed that most grape growers were 41-50
years of age, females, college graduates, and tenants. The majority grows grapes in less
than 1/4 ha of land. Only two varieties are grown in the study area: Red Cardinal and
Green Brazilian, but 93.33% grow Red Cardinal. Rooted cuttings were preferred as
planting material, which they sourced from their plants. Thrips are the common insect pest
on their farm and are very serious, especially during the dry season. All of them used
Complete and Urea fertilizer. Some used foliar and organic compost as fertilizer,
depending on the availability.
Pruning of branches, fruit thinning, and flower clipping are consistently practiced. Most
grape growers harvest 80-90 days from flowering, with 46.67% of the respondents yielding
1.4 kg – 1.7 kg per square meter. Agri-tourism through pick-and-pay was the primary
marketing channel. Based on the PNS for Table Grapes, 56.67% of grape farms have Class
I fruits. Most of the fruit sampled has sweetness below 16 degree Brix. Soil potassium levels
were sufficient in most farms. Majority of the grape farms have acidic soil.
