Hope you are all well. In Pakistan, Fodders are grown at different time periods of the year to fulfill the needs of livestock. In my model, I added two branches (i.e) Rabi fodder( October-Jan) and Kharif Fodder(April-June). Rabi fodder contains Berseem, alfalfa, Oats, and Barley while Kharif fodder contains Sorghum, Bajra, Cowpea. How can we add a single kc value for Rabi and a single kc value for the Kharif fodder crop? It will be a great favor.

Hello,

I assume your model works on monthly time step, thus you can use combination of functions IF, OR and TS (timestep) in expression builder, something like "IF(OR(TS=4,TS=5,TS=6),x,y)

where:
4, 5, 6 - April, May, June,
x - value for Kharif,
y - value for Rabi.

I hope this helps,

Regards,

M Kandera
