  • Conductance is a term given t o the measure of light being absorbed by the leaf. The higher numbers indicate more light is trapped which equates to more chlorophyll. More chlorophyll should translate into more energy produced by the plant and more growth. On all of the Data slides, look a the trends and not the exact numbers. Small plot error ( the extrapolation from small plot to acre) can sometimes distort the view .
  • Remember to point out to people that these are all small plot tests that have been extrapolated to one acre. What is important is to look at he larger trends and not the fact that one earlier bar may be equal or slightly larger than the end bar.

    4. 4. Significant Increase in Marketable Yields Grower’s Secret PROFESSIONAL (GSP) Data Indicates Significant Increase in Tomato YieldsSummary from David Holden….•Standard Practice = 0%•Standard Practice + GSP drench at planting = 39% increase•Standard Practice + GSP drench and single post transplant spray = 26%increase•Standard Practice + GSP drench and four post transplant sprays = 44%increase•Standard Practice + GSP drench and four post transplant sprays with 3-18-18 = 52% increase Preliminary report
    5. 5. TEST PARAMETERS• CROP: Summer tomatoes (Transplants)• LOCATION: Ventura County, California• DESIGN: Randomized complete block• PRODUCT: Grower’s Secret Professional (1 fl. oz./a)• WATER VOLUME: Foliar, 25 to 100 gal/acre (depending on plant size)• PLOT SIZE: 100 sq. ft.

    8. 8. TOMATO YIELD (Tons/Acre)
    9. 9. % MARKETABLE FRUIT
    10. 10. WEIGHT OF FRUIT (grams)
    11. 11. ECONOMICS• INVESTMENT – Cost of Grower’s Secret PROFESSIONAL (GSP) = $17.50 / fl. oz. (wholesale) – Number of applications in test = 5 – Cost of Grower’s Secret PROFESSIONAL = $87.50 / acre (plus fertilizer)• RETURN – Assumed value of one ton of tomatoes = $69.40* – Yield Standard Fertility = 23 Tons = $1,596.20 /a – Yield Standard Fertility + Grower’s Secret PROFESSIONAL = 35.1 Tons = $2,435.94 /a• TRANSLATION – Approximately 52.6% increase in yield and profit (minus fertilizer expenses) * California Tomato Growers Association - 2011 value
    12. 12. ECONOMICS• Translated * to 2011 California average yield (46.3 Tons /a) • 46.3 Tons /a @ 69.40 /Ton = $3,213.22 • 52.6% possible increase from Grower’s Secret PROFESSIONAL = 70.65 Tons /a @ $69.40 = $4,903.37 • INCREASE = $1,690.15 - $87.50 (minus fertilizer costs) • Translated profit per acre = approximately $1,602.65 (minus fertilizer costs)• Investment $87.50 + fertilizer cost• Return on Investment over cost of Grower’s Secret PROFESSIONAL (not including fertilizer ) = as high as 1,840%. * Based on translation from small plot data
    13. 13. SUMMARY“These are some amazing numbers. Very hard to believethis is from 4 drops per gallon of spray water! ”David HoldenWhy did David say this? Grower’s Secret treated plots had: - Statistically higher level of chlorophyll in plants - Statistically larger fruit - Numerically higher percent of marketable fruit - Statistically higher yields
