A champion of Tulare County small farms, Manuel Jimenez, retires in June
Jimenez has a storied California heritage. His grandmother was half Chumash Indian; his father an immigrant from Zacatecas, Mexico. The extended family of farmworkers settled in Exeter, where his grandfather, an early labor organizer, planned a strike in the 1950s, long before Cesar Chavez came on the scene. Subsequent hard feelings forced the family to migrate to other areas for work.
“My family was entrenched in farm labor,” Jimenez said. “I had the good fortune to go to college.”
Completing college wasn’t easy. He married his wife Olga right out of high school, and they immediately started a family. Jimenez worked in the fields and Olga in a packing house while they scrambled to find childcare.
Ultimately Jimenez earned a bachelor’s degree in plant sciences at Fresno State University in 1977. Not long after graduation, he was named senior agronomist for the North American Farmers Cooperative, an organization of 300 small-scale vegetable and fruit producers based in Fresno.
“We were responsible for visiting all the farmers twice annually – 600 farm calls a year,” Jimenez said. “I was overwhelmed very quickly, but learned a lot.”
While working for the cooperative, he met Pedro Ilic, then a UC Cooperative Extension advisor in Fresno County, who encouraged him to apply for a new small farm advisor position in Tulare County.
“I was hired in 1980 and have been here ever since,” Jimenez said.
Jimenez was able to make his first mark on the industry by experimenting with a novel pest control strategy for tomato pin worm on cherry tomatoes, the most valuable crop produced on small-scale farms at the time. Growers were making 15 to 20 pesticide applications per season, and the pest developed resistance to the chemical. The heavy pesticide use also killed beneficial insects that keep leaf miner in check. The result was completely defoliated plants that produced nothing.
Working with UCCE specialists at UC Riverside and UC Davis and other UCCE advisors, Jimenez conducted research proving that dispensing a non-toxic insect pheromone was an effective and economical alternative to chemical treatment.
“This research really paid off because it worked on all tomato types,” Jimenez said.
With this success, Jimenez became established as a valuable resource for the agricultural industry and had opportunities to share the research in statewide and international presentations. His primary goal, however, was sharing agricultural advancements with the small-scale growers in Tulare County. He surveyed the clientele, most of whom were Latino, and found they were unlikely to read newsletters or magazine articles to learn about agricultural technology. But they did listen to the radio.
Jimenez established a relationship with Fresno-based KGST “La Mexicana,” one of the oldest radio stations in California, and developed an agriculturally themed morning radio program in Spanish. Later he regularly appeared on a question and answer program, Entrevistas y comentarios, with host Estela Romo. The collaboration lasted 30 years, until Romo retired.
“It was a great way to reach small growers,” Jimenez said. “On the morning show, we gave them market news every week, and then we went into education on agricultural issues we felt were important – food safety, fertility, pest management.”
A difficult time in his career came during the recession of the 1980s when many small-scale producers lost their farms. The number of small farms in Tulare County dropped from 400 to 70.
“It was heart wrenching,” Jimenez said. “Small growers were so deeply in debt, when the tomato industry crashed, they lost their livelihood and way of life.”
Jimenez came to realize that market forces, more than anything else, influenced the success or failure of small farms. He began to look at new market opportunities for profitable small-scale production, and saw blueberries. New Southern highbush varieties were becoming available, and, with technology to acidify the valley’s alkaline soil, he expected it to be fairly easy to grow the healthful and valuable fruit.
In 1998, Jimenez established variety trials at the UC Kearney Agricultural Research and Extension Center. Each year, the planting attracts hundreds of people to the field station for the annual Blueberry Day. New varieties have been added over the years and new production practices researched. In 2012, Jimenez grafted the most common commercial blueberry varieties on the roots of farkleberry plants (Vaccinium arboreum). Farkelberry is a small, stiff-branched evergreen bush that is more tolerant of alkaline soils than blueberries.
The plants are growing well, Jimenez said. The coming years will reveal whether using this technique will improve the economic viability of California blueberry production.
Jimenez’ service to the people in his community is not limited to his work on the job. In 1993, Jimenez and his wife Olga founded Woodlake Pride, a volunteer organization that puts youth to work in innovative beautification projects throughout the community. The program aims to channel the young people’s time and energy into constructive endeavors and keep them out of trouble and street gangs. In time, Woodlake Pride created the 14-acre Bravo Lake Botanical Garden, the first agricultural botanical garden in California.
Jimenez is now working with the City of Woodlake to secure a grant to improve the safety, infrastructure and esthetics of the garden. If the $1 million grant is approved, new restrooms, drinking fountains, and fences will be added to the community park.
For his work both on the job and in Woodlake, Jimenez has received numerous awards. Among them was the first-ever Tom Haller award at the California Farm Conference in 2008. Jimenez was named the 2000 Citizen of the Year in Woodlake. He was one of three recipients of the California Peace Prize in 2011.
After working continuously since he was a youngster, Jimenez said is looking forward to traveling around the state of California when he retires.
“I was born here, but I haven’t seen a lot of it. I’ve been too busy working,” Jimenez said.
However, he won’t shirk either his professional or volunteer service. Jimenez plans to work with potential blueberry research successors to maintain the research plot at Kearney, and he is considering invitations from overseas’ companies to share his agronomic and community building expertise to a still wider audience.
'Great Day' morning program features UC Kearney Ag REC
The popular morning television program "Great Day," which airs daily on KMPH Channel 26 in Fresno, featured the work of scientists at the UC Kearney Agricultural Research and Extension Center in six live segments during the five-hour program this morning.
Reporter Clayton Clark and photographer Ryan Hudgins arrived at the Kearney greenhouse at 4:30 a.m. to interview the scientists helping California farmers feed the nation and world sustainably.

Western Farm Press runs 1,000-word story on Kearney blueberry event
The annual Blueberry Open House at the UC Kearney Agricultural Research and Extension Center last month warranted lengthy coverage by Western Farm Press.
Freelance writer Dennis Pollock reported that Manuel Jimenez, UC Cooperative Extension advisor in Tulare County, a small-scale farming expert, walked among the mature blueberry plants at Kearney, describing their good points and bad points.
"The perfect blueberry would be one that is big, firm, sweet, easy to harvest and grows in high pH (soil conditions)," he said.
At the event, Richard Molinar, UCCE advisor in Fresno County, small-scale farming, conducted a blueberry tasting, allowing those who attended to vote for their favorite three varieties. He said that variety isn't the only factor impacting flavor.
"Flavor is also affected by weather, soil factors, plant nutrition and irrigation frequency," Molinar said.
Jimenez introduced growers to two new research projects in blueberries:
- Jimenez and Larry Schwankl, Kearney-based UCCE irrigation specialist in the UC Davis Department of Land, Air and Water Resources, have teamed to study the effects of varying irrigation levels on blueberries.
- Jimenez has grafted popular blueberry varieties onto the roots of farkleberry (Viccinium abroreum), which has greater tolerance of alkaline soils like those found in the San Joaquin Valley. By reducing or eliminating soil and water acidification, using the alternate rootstock may provide a significant cut in production costs.

UC aims to improve economic viability of California blueberry farms
California’s abundant sunshine enables growers to produce high-quality, very sweet Southern Highbush variety blueberries. But, blueberry plants are difficult and expensive to establish and maintain, in part because of California's soil chemistry.
“Blueberries are adapted to grow in forests, in acidic soils,” Jimenez said. “We’re growing them in a desert in alkaline soil. That requires that we acidify the soil when we establish the crop and continuously acidify the irrigation water – which is very costly.”
For example, a 2009 Blueberry Cost Study produced by UC Davis calculated that equipment needs for acidification - including a storage tank, pump and monitoring kit - amounts to $5,500. In addition, the growers must purchase large quantities of sulfuric acid to add to the soil and irrigation water.
Reducing acidification cost is the goal of a new blueberry trial at Kearney, in which Jimenez has grafted the most common commercial blueberry varieties on the roots of farkleberry plants (Vaccinium arboreum). Farkelberry is a small, stiff-branched evergreen bush that is more tolerant of alkaline soils than blueberries.
So far, the two-month-old plants seem to be growing well in their naturally alkaline soil. The coming years will reveal whether using this technique will improve the economic viability of California blueberry farms and provide California consumers with local, healthful and delicious blueberries at a reasonable cost.
The project is being conducted in collaboration with Oregon State University and Florida State University.

Not all blueberries are alike
As blueberries have become more a popular plant for home gardening, variety choices have blossomed, wrote Laura Christman in the Redding Record Searchlight.
When it comes to flavor it's hard to go wrong with any variety of homegrown blueberry, said Manuel Jimenez, a University of California Cooperative Extension farm advisor specializing in blueberries.
"All the varieties that ripen on the plant are good," said Jimenez, who is based in Tulare County.
Among the varieties Jimenez recommends are Misty, Reveille, Sharpblue, Star, Legacy, Emerald and Jewel.
The best time to plant blueberries is in the fall, when the ground is warm and plants can establish roots, Jimenez said. However, most nurseries don't feature them in fall. The biggest selection of blueberry plants is available now.
