Purpose

Since the impetus to quantifying plant growth rate related to the efficiency of biostimulant, we exploit relative growth rate (RGR) which mathematically should be written as:

and expand to

then in the case of two harvest, our equation [1] could calculate as:

As known M1 (unit:g), by using equation [2]&[3], for each rice, we'll get a predicted M2 (unit:g), the alternative mass of rice, and then we calculate the relative deviation between each treatment and the control as the X value and also calculate the relative deviation between exact M2 (unit:g)and the control as the Y value.

Among these, "a" represents any treatment group.

Using linear regression, our mean value of exact M2 (unit:g)are fit in both the prediction one and the one of respective data, which could not only well explain the better concentration to dilute the supernatant from Bacillus subtilis RM125/PQQ culture in straw liquid but well evaluate the plant mass and the total rice harvest further.
