Feb. 10 citrus tour (9:30 a.m.–3:30 p.m.)
The citrus tour will visit two locations: University of California Lindcove Research & Extension Center and McKellar Family Farms.
Established in 1959, the UC Lindcove REC has more than 100 acres of citrus in the heart of the San Joaquin Valley. At the center, researchers conduct studies on citrus varieties, horticultural techniques and pest management. The UC Lindcove REC portion of the tour will include a display and tasting of citrus varieties.
Lunch is provided at McKellar Family Farms, where visitors will tour the citrus orchards, view equipment and get a better understanding of the process from tree to table. By the end of the tour, visitors will have an understanding of how much care and forethought goes into producing top-quality fruit, in addition to the research conducted to improve growing conditions.
Tour tickets cost $45 and include choice of lunch. For more information, visit https://www.worldagexpo.com/attendees/agriculture-tours.
Empowering California youth through food smart families
The health of California youth reflects this disturbing national trend. To address the challenge of childhood obesity statewide, the California 4-H Food Smart Families program will be implemented at four sites in Fresno, Orange, Sutter-Yuba and Tulare counties this year. Additional UC partners will include the Expanded Food and Nutrition Education Program (EFNEP) and CalFresh.
Youth need to increase consumption of dark green veggies and whole grains, and decrease intake of sugar and saturated fats. The objective of California 4-H Food Smart Families is to increase knowledge and create behavior change related to nutrition, cooking, gardening, physical activity and food preparation. The program engages youth 8 to 12 years old and teens in 4-H Healthy Living programming. Youth will be directly reached through lessons delivered at after-school sites, low-resource elementary schools and organized field days at four UC Agriculture and Natural Resources Research and Extension Centers (REC): Kearney REC in Parlier, South Coast REC in Irvine, Sierra Foothill REC in Browns Valley and Lindcove REC in Exeter. The program is structured around positive youth development curricula and practices which provide an intensive engagement of underserved children, teens, families and other stakeholders. Local 4-H teens will be recruited and trained to deliver programs and assume leadership roles.
Programming at California sites will get underway this fall and will continue through the school year. Look for more exciting California 4-H Food Smart Families news in the coming months as programming and activities kick into high gear.

Muy cerca de la realidad la producción de aguacates en el Valle de San Joaquín
Los aguacates son nativos de bosques semi tropicales de alta elevación en México y Centroamérica. Una fruta deliciosa y altamente nutritiva, el cultivo de aguacates se ha extendido a todo el mundo. En California, los cultivadores están teniendo éxito comercial en áreas con climas templados todo el año, como los condado de San Diego y Ventura.
No obstante que los aguacates son sensibles a las heladas, no es precisamente el clima invernal el mayor impedimento para la producción de aguacates en los valles interiores del estado. Es el calor.
“Las hojas de la planta tienen estomas, unas pequeñas aberturas que permiten que el vapor del agua salga de la planta para así enfriar su superficie”, explicó Arpaia. “Trabaja algo así como la transpiración en las personas. La humedad sale de los poros y refresca la piel”.
Las estomas de las hojas de los aguacates Hass – la variedad más favorecida por los consumidores de California – se cierran cuando la temperatura rebasa los 90 grados. La humedad no es liberada por las estomas cerradas y la planta se recalienta.
“Para cultivar aguacates en el valle, necesitamos contar con una variedad que pueda tolerar el calor mejor que el Hass”, dijo Arpaia.
Durante los cuatro últimos años, Arpaia ha plantado variedades de aguacates seleccionadas por la Universidad de California en Riverside en el Centro Lindcove de Investigación y Extensión de la UC cerca de Exeter. Hoy día se cultivan 12 variedades diferentes en esa parcela. Las selecciones de UC Riverside han sido sometidas a pruebas rigorosas en cuanto a producción, cuánto tiempo puede permanecer el fruto maduro en el árbol y su calidad comestible.
“Los aguacates que estamos probando en el campo cuentan con una calidad comestible comparable al Hass”, manifestó Arpaia.
Lindcove está situado donde el suelo del valle se eleva ligeramente hacia la Sierra Nevada. La inclinación permite que el aire se desplace a elevaciones más bajas, dando a los agricultores del área una ventaja de unos pocos grados durante el invierno. La geografía ha hecho del área una importante ubicación para la producción de cítricos. Y los aguacates que toleren el calor podrían ser una alternativa.
Los productores de cítricos de la zona este podrían buscar otras opciones si la enfermedad del Huanglongbing (HLB) llega a esta región. La plaga que propaga el HLB, el psílido asiático de los cítricos, ya se ha establecido en algunas partes del valle y sigue propagándose. Una vez que un árbol es infectado con HLB, no tiene cura.
“Los cultivadores han hecho buen dinero con los aguacates”, indicó Arpaia. “En el Valle de San Joaquín, el agua es relativamente barata y contamos con agua de mejor calidad que el condado de San Diego. Hay suelos buenos y bien drenados. La sensibilidad de los aguacates a las heladas es similar a la de los limones. Si los granjeros cuentan con una propiedad en la que pueden cultivar limones, podrían intentar con los aguacates”.
