    Introduction

  • Introduction

  • Water Use Efficiency = Yield / Water Input

    Water Use Efficiency, WUE

    WUE =

  • Resource Use Efficiency, RUE

    RUE =

    Resource Use Efficiency = Yield / All Farm Inputs

  • PRECISE APPLICATIONS OF WATER IS CRITICAL TO:

    1. General Growth 2. Vegetative Shoot Growth3. Growth of Roots4. Flower Bud Formation, Bloom and Fruit Set5. Fruit Growth and Quality6. Prevention of Stress, Diseases and Pests

    Adapted from Western Fertilizer Handbook

  • BMP’s for Peach Irrigation

    1. Consumptive Use: 36”/year 2. Peak ET: 0.20”/day (35-40 gals/day)3. Micro-Irrigated (90% EU) trees need

    1.5”/week; overhead sprinkler (60% EU) irrigated trees need 2.3”/week

    4. Irrigation is crucial during last 30 daysAdapted from Rutgers “Best Management Practices for Irrigating Peach Trees” (Jerome Frecon)

  • BMP’s for Peach Irrigation

    5. Damage from lack of moisture is permanent6. Rootzone is 24” deep but 80-90% of feeder

    roots are in top foot where 70% of moisture is extracted.

    7. Micro-irrigation should wet 25-60% of the root zone

    8. Irrigation increases yields by about 25% due to fruit size

  • Drip/Micro for Permanent Crops

    Dripline

    Hose and On-Line Emitters

    Jets/sprays

    Micro-Sprinklers

  • Dripline: Single or Dual

  • Dripline: Subsurface Drip Irrigation, SDI

  • What’s Next?

    21st Century Orchard project Kevin R. Day, Theodore M. DeJong, Rebecca C. Phene, and Claude J. PheneUniversity of California, Kearney Agricultural Research and Extension (KARE)

    1. Primary Goal: • Compare convention height trees (12-13' tall) with pedestrian height (6-7') trees at

    4’ to 8’ tree spacing grown on UC-developed size reducing rootstocks. • Plant two cultivars of peach/nectarine, one ripening in June and one in August

    2. Secondary Goal:• Compare conventional micro-sprinkler irrigation of conventional height trees vs.

    subsurface drip irrigation in the pedestrian trees.

  • Two varieties (an early ripening and late ripening) of peaches are planted on three rootstocks. One rootstock is repeated on two planting configurations:

    The 'conventional' treatment = Nemaguard rootstock, planted 8 ft x 18 ft, will be topped at 12-13 ft tall; has both varieties. Irrigated with microsprinklers.

    Size controlling rootstock, C9 ("90" % of the vigor of Nemaguard rootstock), planted 8 ft x 15 ft, will be topped at 6-7 ft tall; has both varieties. Irrigated with SDI.

    Size controlling rootstock, C6 ("60" % of the vigor of Nemaguard rootstock), planted 8 ft x 15 ft, will be topped at 6-7 ft tall; has both varieties. Irrigated with SDI.

    Size controlling rootstock, C6 ("60" % of the vigor of Nemaguard rootstock), planted 4 ft x 15 ft, will be topped at 6-7 ft tall; has both varieties. Irrigated with SDI.
