Calculate relative yield
Description
This function calculates the relative yield of an observed dry matter yield compared to the reference dry matter yield in the Swiss fertilizing guidelines (Sinaj et al. 2017).
Usage

Arguments
var_crop |
string with name of crop type, must match with the Crops in the C_input_crops_LUT |
var_yield |
observed dry matter yield (tDM/ha) |
Value
