2.6.1 Changing the SCI Equation
The SCI equation may be modified for installations where no Rd color
data is available. Follow the steps below to change the SCI Equation:
1. Estimate a typical average value for the Rd of your cotton.
2. Multiply that Rd value by 0.65 (i.e. 74.0 x 0.65 = 48.1).
3. Add the results to the -412.7 constant (i.e. -412.7 +48.1= -364.6).
4. Change the constant coefficient from -412.7 to -364.6.
5. Replace the Rd coefficient with zero.
