Yield deviations (%) from base period at different sowings
Periods and RCP March April May June
NT_rcp_4.5 10.3 8.6 1 18.8
NT_rcp_8.5 2.7 5.3 4.1 16.5
MT_rcp_4.5 14 12.2 0 23.7
MT_rcp_8.5 19 10.1 2.2 28
ET_rcp_4.5 22.5 15.4 0 27.8
ET_rcp_8.5 25 23.7 16.4 30.4
NB: NT, MT, ET and RCP represents the near term, mid-term, end term and representative concentration pathways respectively; while the numbers 4.5 and 8.5 are the expected extra energy (energy out of balance) retained due to the greenhouse gas concentrations in the atmosphere. Future yield deviations were computed from the respective historical sowing windows and all the values indicated in the table above are negatives (meaning yield has simulated to reduce in all sowing windows from their respective bases).
