  • September Orchard Tasks – Pistachios

    Pistachio harvest ended earlier than usual this year, but growers should not stop irrigating their orchards just yet. The early finish creates a longer post-harvest period before trees enter dormancy, making proper irrigation especially important.

    Research by Daniele Zaccaria, Mae Culumber and Anderson Safre of the University of California Cooperative Extension indicates that pistachio trees continue using water after the nuts have been removed. Although harvest is complete, evapotranspiration—the loss of water from the soil and through the trees’ leaves—continues until the trees become dormant.

    Because the post-harvest season will be longer this year, growers should continue monitoring their orchards’ water needs. Stopping irrigation too soon could place unnecessary stress on trees as they prepare for next season.

    However, the researchers suggest growers may be able to conserve water through carefully timed deficit irrigation. This practice involves applying less water than the orchard would normally use during selected periods. When managed properly, deficit irrigation may reduce water use by about 20% with little to no effect on the following year’s harvest.

    The key is timing. Growers should consider orchard conditions, soil moisture and the trees’ water needs before reducing irrigation. An early harvest does not mean water use has ended, and post-harvest management can play an important role in supporting the next crop.

  • Oakville Bluegrass Cooperative Opens Enrollment for Reimbursable Cover Crop Seed

    Oakville Bluegrass Cooperative is pleased to announce open enrollment for the USDA’s newly expanded Advancing Markets for Producers (AMP) program—building on last year’s successful Partnerships for Climate-Smart Commodities initiative. This year, the program is expanding direct funding to producers, and the new incentive will reimburse producers for the purchase of up to ten acres worth of seed for any perennial conservation cover.

    One choice for the incentive, Oakville bluegrass, is dormant from April through September and doesn’t compete with cash crops for water or nutrients making it ideal for California permanent crops. This low growing, drought tolerant cover crop will last over ten years when well managed, significantly reducing labor and input costs for growers.

    As part of the USDA’s AMP initiative, producers can now access:

    • Full seed cost coverage for up to 10 acres of Oakville bluegrass
    • An additional $100/acre incentive for up to 100 acres.
    • Support in the form of a grower’s guide, educational field days, and guidance on carbon removal credits.

    “We’re thrilled to put more money in producers’ hands under the Advancing Markets for Producers program, ” said Jeff Thiel, Director at Oakville Bluegrass Cooeprative. Perennial cover like Oakville bluegrass can reduce operating costs over time while also building soil health and conserving water. We’re especially excited to help producers tap into the growing carbon credit market while establishing a proven, cost-effective cover crop.”

    Interested growers can attend an online informational session on October 21 at 11 am by registering at https://bit.ly/ampobc25 or visit https://www.obc.ag/advancing-markets-for-producersfor more information.

    The Oakville Bluegrass Cooperative collaboratively creates solutions to the most pressing challenges facing growers. Members work together to uncover best practices in sustainable agriculture tailored to the needs of specialty crop growers. Learnings are shared so all members can benefit from adopting practices that will ensure the long-term sustainability of profits from their farms.
