-|''​growthstartmodel''​|//​0/​1/​2/​3//​|defines if varying start of the growth season should be used. Default (0) is no variation, then [[start:​hype_file_reference:​CropData.txt|CropData.txt]] constant parameter bd2 is used for nutrient uptake and plantday for irrigation. The alternatives are (1) to used varying growth season start for nutrient uptake, (2) to use varying growth season start for irrigation but not for nutrient uptake, ​and (3) to use varying growth season start for irrigation and nutrient uptake. For the alternatives ​the season start is calculated based on degreedays (equation defined by parameters in [[start:​hype_file_reference:​CropData.txt|CropData.txt]]).|+|''​growthstartmodel''​|//​0/​1/​2/​3/4//|defines if varying start of the growth season should be used.
