Resolution IV 8-compound OACD Design. 59 combinations for 8-compound experiment at three different concentration levels. Level 0 (input -1 in the OACD table) indicates the absence of a compound. Level 1 and 2 (inputs 0 and 1 in the OACD table, respectively) represent two compound concentrations. The experimentally measured %Yield used in WisDM Green analysis is determined with respect to the control plants using Equation (1) (N = 3). Potato Starch (Starch), Humic Acid (HA), Citric Acid (CA), Ethylenediaminetetraacetic Acid Iron (III) (EDTA-Fe/EDTA), 6-Benzylaminopurine (6-BAP), and Seaweed Extract (SWE).
