Roots’ RZTO heating technology boosts yield of Yardlong Beans by 40 percent
•Heated plants increased yield of Yardlong Beans by 40 percent compared to unheated control crop.
•Root Zone Temperature Optimisation (RZTO) heating system stabilised crop roots at optimal 20 degrees, despite ambient air temperatures frequently dropping to five degrees.
•Follows successful RZTO heating and cooling on multiple crops including basil, lettuce, chives and cucumber.
•Roots is the only company with commercial
Roots Sustainable Agricultural Technologies Limited (ASX: ROO, Roots or Company) Root Zone Temperature Optimisation (RZTO) heating technology has increased the yield of Yardlong Beans, by 40 percent more than unheated control crops.
Yardlong Beans (Vigna unguiculata sesquipedalis), are a staple crop in most Asian cuisines as well as equatorial Africa and South America.
The results came from a grower in Southern Israel who had purchased a Roots RZTO system and conducted the growing in hoop houses during the Israeli winter from November 2018 to March 2019. The region is arid and known for severe temperature fluctuations between day and night.

Roots CEO, Dr Sharon Devir said, “The Yardlong Beans family is cultivated for human food throughout Asia, northern Africa and Southern America and is a staple of most Asian cuisines. However, a challenge for these crops that are generally grown around the tropics and temperate areas is that cool temperatures significantly impact the production and quality of the harvest. So they’re typically only grown in summer months. Our RZTO heating and cooling technology has mitigated external weather conditions, allowing the farmer to grow Yardlong Beans
The farmer who grew the crops, Sharon Cheri, said ,“Roots’ heating technology has lengthened our growing cycle, increased crop yield and reduced incidences of plant disease. In addition, root zone heating uses significantly less energy than air heating systems.”

About Root Zone Temperature Optimization (RZTO):
Root Zone Temperature Optimisation (RZTO) optimises plant physiology for increased growth, productivity and quality by stabilising the plant’s root zone temperature. Leveraging the principle of Ground Source Heat Exchange (GSHE), Roots installs a
This significantly increases yields, increases growing cycle planting options, improves quality, mitigates extreme heat and cold stress while significantly reducing energy consumption by stabilising and optimising the roots zone temperature.
