TREATMENTS
  • T0: Grower Std. (Check)
  • T1: VEGRO® + Grower Std
AGRONOMIC PROTOCOL
  • Location: Florida; Better crops research farm; Block 9, section N, beds 2-4.
  • Investigator: John Curtis, PhD
• 13-week treatment (3 months)
  • Start date: Sept. 28, 2016
  • Completion date: Dec. 19, 2016 • Trial reliability: HIGH
METHODOLOGY
  • Plastic beds (32-inch top, 6 inches tall) were prepared on a 6-foot row spacing. Tomato (cv. charger) were hand-transplanted into one row/bed (18 inches plant spacing) on 8/25/2016.
  • Each plot was 30 feet in length x 3 beds (30 feet length x 18 feet width)
  • Each treatment was replicated four (4) times.
EVALUATION (Fruit count & weight)
  • 3 Harvests
  • All fruits were counted and weighed in lbs (100%)
  • The cumulative fruit count and weight were also tabulated at 21 DAH (Days After Harvest)
PHYTOTOXICITY

Plants were examined for signs of phytotoxicity (stunting, discoloration, etc.) at 21 DAH using a 0-100% rating scale; 0 = no phytotoxicity and 100% = dead plants.

PROGRAM STANDARD RECOMMENDED

• To combine the improvement of the efficacy of the fungicides + the quality yield, we recommend this program.

Study Results

+21%

Extra yield in Fruit count when Vegro® added to GS (T1)

+340

Extra Pcs of fruit count when Vegro® added to GS (T1)

+15%

In Weight count when Vegro® added to GS (T1)

+58

Lbs of weight count when Vegro® added to GS (T1)

Vegro® (T1) is zero Phyto-toxicity

Study conducted in Florida by John Curtis, PhD, (Better Crops LLC) from September to December 2016 in open field. Plants were staked and maintained at a commercial level with fertilizer/insecticide/fungicide (liquid fertilizer through drip every other day). 3 Harvests: In fruit count, VEGRO® shows the best results +21% in average and 3rd harvest shows the highest gap: +48%

Objectives: Evaluate the interest of VEGRO® for tomato yield.
