In order to determine the most effective dose of Growthful’s concentrate, the Aqueus team conducted a trial on Broccoli, spearheaded by Lance Beem with Beem Agro-Sciences.  Within this study, Aqueus set out to determine Growthful’s effect on Broccoli yields and profits.

Background

• Location: Chular, California, USA
• Start Date: December 15, 2020
• Harvest Date: March 24, 2021
• Irrigation: Sprinkler, 1 Acre foot Total
• Replicates: 6 Replicates per Treatment, 4 subsamples per replication, 4 Treatments and an Untreated Check

Plot Design

• Randomized Complete Block (RCB)
• Length: 25 feet
• Width: 3.3 feet (40” row spacing)
• Area: 82.5 sqft.

Application

Growthful was tested in three different doses:  6.4 oz/10, 12.8 oz/10, and 25.6 oz/10

Application 1

12/15/20 – Post Seeding/Pre-Emergence

Application 2

12/29/20 – Young Seedling Stage/First True Leaf

Application 3

1/11/21 – 4th True Leaf Stage

Application 4

2/4/21 – 10-12 Leaf Stage

Results

The optimal Growthful concentration (12.8 oz/10) was not only determined but it produced positive effects on both yield size and quality!

The optimized dose of Growthful produced a 7.9% increase in broccoli yields
ROI: At the current price of $0.85/lb, this yield increase directly equates to 6.7¢
additional profit per pound
