Commercial Agriculture

cowsWith the closure of many sugar and pineapple plantations in Hawai‘i, large areas of prime agricultural lands became available for diversified agriculture. Hawai‘i’s mild and year round climate allows Hawai‘i’s farmers to grow a large variety of fruits, vegetables, flowers, ornamental plants, and livestock. Production, transportation and manufacturing inputs are intrinsically costly in Hawai‘i. However local farmers and business are able to compete by providing products that add value or serve niche markets. Import substitution also expands the local market for products, increases employment, and retains dollars within the state. Examples of high-value or value-added agri-products with sizable markets for which Hawai‘i has demonstrated global competitiveness include flowers, landscape and nursery crops, seeds, tropical fruits and nuts, herbs, beverages, queen bees, and medicinal and cosmetic plant derivatives. Access by local agribusinesses to superior varieties, best production or cultivation management practices, processing and handling technologies, and market information is key to long-term success. This section provides resource information for producers and others that the College provides and links to College and other resources to crop and livestock production.

Turfgrass Management
Turf and green industry contributes significantly to Hawai‘i’s economy. Due to biology, ecology, intensive management and disturbances, turf system oftentimes has different and specific pest management issues compared to traditional agricultural systems. In addition, the year-round growing conditions in Hawai‘i are not only good for turfgrass, but also for a diverse range of turf pests. These unique turf management challenges in Hawai‘i call for effective management strategies based on applied research. The overall goal of the turf management program is to provide effective turf pest management options to diverse stakeholders in Hawai‘i, and on a broader sense, turf and green industry in tropical regions of the world, through extension education and outreach activities built on applied research.
