Objectives: To quantify seasonal yields of fresh market strawberries in a California environment utilizing Vegro®
For a better view of the graphs and charts, reposition your mobile device into landscape mode.
Variety Used: Radiant
• The best treatment is High Rate Foliar Vegro® [T3]. With this program and treatment, we obtain +$2,560 per acre as Cumulative differiential from the Grower Standard, cost of the program Vegro® deducted. +$2,560 per acre as RETURN ON INVESTMENT Vs the Grower Standard.
• +25% more Return on Investment between Foliar High Rate (red line) and Soil Low Rate (green line) with Vegro®
• We speak here about +$2,560 NET cumulative return investment per acre and above the Grower Standard.
• +$1,553 per acre for Low Rate by foliar with Vegro® or +2,049 per acre by soil at Low Rate
• There is for sure room in the budget of the grower to consider Vegro® treatment.
Notes:
• W = week and one week is equal to 7 consecutive days of picking, one pick is equal one day.
• NET = Vegro® program cost is deducted from the results.
• By passing the cursor on the graph you will visualize the raw data.
• The best treatment is High Rate Foliar Vegro® [T3]. With this program and treatment, we obtain $20,937 per acre as Cumulative Marketable Production, Net Return by Pick week. With the Grower Standard [T1], the black line on the graph, we obtain: $18,273 per acre.
• [T3], Vegro® treatment in High rate version and applied by foliar application generates a very significant +$2,664 per acre. Once deducted the cost of the program in High Rate version, then we obtain NET +$2,560 Per acre.
• By comparaison with the [GS] it makes a very noticeable gain of yield of about +14.6% per acre.
Notes:
• W = week and one week is equal to 7 consecutive days of picking, one pick is equal one day.
• NET = Vegro® program cost is deducted from the results.
• By passing the cursor on the graph you will visualize the raw data.
• The best treatment is High Rate Foliar Vegro® [T3]. With this program and treatment, we obtain 2,529 trays per acre as Cumulative Marketable Production, Net Return by Pick week. With the Grower Standard [T1], the black line on the graph, we obtain: 2,254 trays per acre.
Accordingly, Vegro® High rate by foliar application, [T3] generates +275 trays per acre which compared to the [GS] makes a very noticeable gain of yield of about +12.2% per acre.
Notes:
• W = week and one week is equal to 7 consecutive days of picking, one pick is equal one day.
• NET = Vegro® program cost is deducted from the results.
• 1 tray is about 8 Lbs
• By passing the cursor on the graph you will visualize the raw data.
• Data In trays per acre.
• This graph shows the improvement of the production by week and allow so to better visualize the early maturity incidence with Vegro®.
• Each bar show the Vegro® treatments and the black line the Grower Standard [T1]
• In comparison between [T3] HR Foliar and [T1] the Grower Std, the first week which is W1: +20% more yield; W2: +35.6%; W3: +14.5%; W4: 0%
• What do we see? A clear improvement of the production (trays per acre) for the Vegro® treatments compared to the GS [T1]. The High Rate Foliar treatment, present the most promising results. Please check the graphs #5,6 & 7 to obtain more details.
Notes:
• W = week and one week is equal to 7 consecutive days of picking, one pick is equal one day.
• By passing the cursor on the graph you will visualize the raw data.
• In trays per acre
• Curbs represents the gain of yield with Vegro® Vs the Grower std (Zero line is the GS [T1])
• This graph is about to evaluate the early maturity benefits of Vegro® treatments Vs Grower Std.
• Red line which is [T3] High Rate Foliar, shows a very constant and homogenous curb way above the GS [T1]. It is above all the others and all along the two first weeks.
• Pale red line [T4] Low Rate Foliar shows the same trend as HR Foliar but with less difference with the GS.
• Soil treatments (green curbs) either HR or LR show less early maturity and get closer to foliar treatments data on the last week, when precisely the price of the market has dropped.
• In resume, best return on investment is on the two first weeks where the market is the highest. This where precisely the foliar treatments with Vegro® are the most performant.
Notes:
• W = week and one week is equal to 7 consecutive days of picking, one pick is equal one day.
• By passing the cursor on the graph you will visualize the raw data.
• 58% of the overall gain of yield for [T3] HR Foliar Vegro® is spread out over the two first weeks of harvest
• No significant difference in Week 4 vs the GS
• Accordingly, 100% of the gain of yield is occurring on the 3 first weeks of harvest.
Cumulative Early maturity for W1,W2 [T3]
• Price per 10 Lbs flat equivalent
• Net Return to Grower is Net Price to Grower after picking, cooling, and Hauling
• The terminal price for 1Lb is less $6.00
• Two first weeks are at $11 Net Price Returned to the Grower when the 2 remaining weeks (W3 & 4) are respectively at $8.7 and $6.7.
• According the graph #6, [T3] High rate Vegro® treatment shows that most of excedent of production (58%) compared to the Grower Std is occurring over the two first weeks of harvest and where the market price is the highest.
• Vegro® is not only improving the quality yield on strawberry but it does improve the early maturity where the Net price return is the most profitable.
Notes:
• W = week and one week is equal to 7 consecutive days of picking, one pick is equal one day.
• W1 is from: 12/11/17..01/05/18; W2 from: 01/08/18..01/29/18; W3 from: 01/31/18..02/21/18; W4 from: 02/26/18..03/19/18
