About us

The UC Kearney Agricultural Research and Extension Center (KARE) is a world-class research operation in the heart of California’s San Joaquin Valley from which flows a steady stream of practical ideas and solutions ready for implementation by the region's farmers.

Scientific research conducted at Kearney has advanced understanding of every aspect of production and environmental management related to the valley's bounty of fruits, vegetables and field crops. It is no coincidence that Kearney is located in what has become the state's No. 1 agricultural county, on land that is some of the most productive in the world.

With resident faculty conducting basic as well as field research, the center is like a mini university campus. It also serves as a research base for dozens of off-station scientists from UC Riverside, UC Davis and UC Berkeley, and farm advisors from San Joaquin Valley UC Cooperative Extension. Not surprisingly, it is the most utilized off-campus agricultural research facility in the UC system. Thousands of people visit the center or participate in its meetings, workshops, field days and seminars annually.

Kearney's 330 acres of research facilities encompass a state-of-the-art greenhouse, a postharvest laboratory, a mosquito control laboratory, multiple insectaries, and academic and administrative offices. Its controlled field studies occupy 260 acres of orchards, vineyards and fields.

KARE scientists have developed novel cultivation, pruning and planting methods for the major valley crops, while at the same time studying newer specialty crops like blueberries and Southeast Asian fruits and vegetables. Kearney has also been one of the key testing grounds for sustainable farming methods, such as integrated pest management (IPM), biological control, water conservation and nitrogen management.

Kearney is one of nine UC Agriculture and Natural Resources research and extension centers in California. View the video below for more information on the network of RECs:


Turn-of-the-century origins

UC has supported off-campus research sites for more than a century. In the 1880s, UC Berkeley professor Eugene Hilgard established a 20-acre field station southeast of Tulare for variety tests and work on the reclamation of alkali soils. Kearney's origins go back to the turn of the 20th century, when prominent developer M. Theodore Kearney willed his 5,400-acre estate west of Fresno to the University for educational purposes. UC sold some of the land, generating revenue to establish the Kearney Foundation, which later would supply matching funds for a research center named in Kearney's honor.

In the early 1960s, the San Joaquin Valley was fertile ground for the expansion of agricultural science and technology. However, prominent San Joaquin Valley agriculturists knew that problems peculiar to the valley could “tarnish the bright potential of this unique farming area,” according to noted banker and agricultural economist Jesse Tapp (Reedley Exponent, June 2, 1965). Challenges included irrigation management, alkali soils, pests and diseases, evaluating new tree and vine varieties, and developing rootstocks with resistance to nematodes and disease.

In 1959 the Fresno County Farm Bureau took the lead in forming the San Joaquin Valley Fruit and Grape Station Trust, which collected contributions from farmers, fruit packers, agricultural suppliers and others. Gifts ranging from $2 to $10,000 amounted to $128,500 to match Kearney Foundation funds. After serious consideration of several sites, a committee suggested the Mosesian Ranch, a uniform alluvial plain with favorable sandy loam soil. UC consented and the 195-acre Mosesian Ranch, at the intersection of Manning and Riverbend avenues between the cities of Reedley and Parlier, was purchased on Aug. 12, 1962.

Officials broke ground nearly two years later on two houses, a laboratory and a building for machinery storage and equipment repair. A year later, on May 26, 1965, the Kearney Horticultural Field Station was formally dedicated. Visitors took tours to see research plantings of tea, grapes, peaches, plums, olives, nectarines, almonds, walnuts and other crop trials that were already under way.

The center steadily grew to accommodate new research needs, reflecting the region's rapidly expanding and changing agricultural economy. In 1985, the last 65 acres of land was purchased, bringing the total acreage to the present 330.
