From the ann, looks like more than a single plant was trialed,
"..GPP subjected coal from the Gippsland Basin in Victoria to the OHD process and the resulting bio-stimulant fertiliser liquid was applied to test crops at application rates of five litres per hectare up to 70 litres per hectare.
OHD usage confirmed to increase wheat yields by 300% utilising OHD rates in a range between 5 litres and 35 litres per hectare.
The other factor which is important in terms of wheat production is the number of heads of wheat per plant...."

YIELD:
i must agree with you, even if Gpp OHD can do only 30%, instead of 300%,
it will be very impressive.
For e.g.,
Well established European bio-stimulant producer Valagro's new product YieldON can increase yield by only 15%.
"...Valagro, a leading company in the production and marketing of biostimulants and specialty nutrients, presents YieldON, the new biostimulant specifically designed for row crop nutrition...
..."Some experimental trials conducted in Brazil have shown an average productivity increase of 13-15%
in relation to the standard level"..
Benoit Genot, Global Marketing Director of Valagro:
"The row crop market is based on intensive cultivation systems aimed at obtaining increasingly higher yields to meet the growing demand for food from the world's population. Rice, wheat, corn and soybeans are the crops used most to meet this constantly increasing worldwide demand for food, and they occupy most of the agricultural surface area throughout the world...
...For these reasons, YieldON is a viable solution that ensures high quantity and quality yields within the constraints of greater crop efficiency."
