Improved Yields on Citrus and Almonds with OneUP™

Background

OneUP™ is designed to produce stronger root systems, increased yield , and improved soil health. It can be applied on or near the roots or used as a foliar application midseason. Testing was needed to determine its effectiveness in increasing yields in the vineyards and orchards of California.

Introduction

Agronomist Stephen S. Deitz of Sawtooth Ag Research ran field trials on citrus (Cara cara navel) and sweet almonds (Nonpareil) in the heart of California's Central Valley. The trial evaluated effects of a new fertilizer product, Simplot OneUP™, on yield of orchard and vineyard crops.

Methods

The treatments were delivered to the trees with a combination of foliar and soil applications throughout the season. Each study was a randomized complete block design with multiple replications.

Results

Application of OneUP™ increased mean yields in almonds by 200 lbs/acre while maintaining nut weight. Citrus increased yield by 920 lbs/ac with 10 percent increase in fruit weight.

 

Almond OneUP™

  • Sweet Almond
  • Location: Poplar, CA
  • Investigator: Sawtooth Ag Research--Stephen S. Deitz
  • Study Design: Randomized complete block--replicated
  • Soil: Sandy loam
  • OneUP™ treatments: A total of 10 gallons + 3 quarts per acre of OneUP™ was applied during the growing season.

Summary

A season-long program of OneUP™ was applied to mature almond (cv. Nonpareil) to evaluate yield and crop response. OneUP™ was applied at bloom and post bloom at 1 and 2 qt/ac in a foliar application program. In addition, OneUP™ was applied twice as a drench at 5 gal/ac to the soil while irrigation was running at nut sizing stages just after jacket split and again 30 days later. Foliar applications were made with a mistblower and delivered at 100 gal/ac. Each plot consisted of four trees, and each treatment was replicated four times. Yield data was taken by sampling harvested nuts in the windrow and determining the number of nuts per plot. A 100 nut sample was taken from each plot and cracked out for turnout and meat weights. The untreated plots were found to have nut population of 28.7 nuts per sq./ft/ (not in a windrow) and nut meat weight of 1.08 g/nut, corresponding to yield of 1,141 lbs/ac of nut meats. OneUP™ treated trees averaged 34.5 nuts per sq/ft., nut meat weights of 1.05 g/nut, and corresponding yield of 1,341 lbs/ac.

Citrus OneUP™

  • Cara Cara Navel
  • Location: Elderwood, CA
  • Investigator: Sawtooth Ag Research--Stephen S. Deitz
  • Study Design: Randomized complete block--replicated
  • Soil: Clay loam
  • OneUP™ treatments: A total of 10 gallons + 1 quart per acre of OneUP™ was applied during the growing season.

Summary:

A season-long program of OneUP™ was applied to fourth leaf citrus (cv. Cara cara navel) to evaluate yield and crop growth. OneUP™ was applied at bloom and petal fall at 1 and 2 qt/ac in a foliar application. An additional 5 gal/ac soil drench was made twice with irrigation at bloom and fruit size. The foliar applications were made with a mistblower and delivered at 100 gal/ac. Each plot consisted of four trees, and each treatment was replicated four times. The untreated plots averaged 120 fruit per plot weighing 61.4 lbs with average fruit weight of 0.51 lbs. OneUP™ treated trees averaged 136 fruit per plot weighing 75 lbs with an average fruit weight of 0.56 lbs.
