abstract = {Climate change will bring warmer and wetter conditions and
more frequent extreme events in the Nemoral climate zone.
These changes are expected to affect maize growth and
yields. In this study, we applied the AgroC model to assess
climate change impact on changes in growing environmental
conditions, growing season length, yield and potential yield
losses due to multiple abiotic stresses. The model was
calibrated and validated using data from dedicated field
experiments conducted in Lithuania during four
meteorologically contrasting years (2015, 2016, 2017 and
2019). We simulated the climate impacts on rainfed maize for
long-term future climate conditions from 2020 to 2100 under
the RCP2.6 (low), RCP4.5 (medium) and RCP8.5 (high) emission
scenarios. As a result, we found that air temperature, sum
of growing degree days and amount of precipitation during
the growing season of maize will increase, especially under
medium and higher emission scenarios (RCP4.5 and RCP8.5),
with significantly positive effect on yields. The simulation
results showed that average maize grain yield will increase
under RCP2.6 by 69 kg ha−1 per decade, under RCP4.5 by 197
kg ha−1 per decade and under RCP8.5 by 304 kg ha−1 per
decade. The future potential maize yield reveals a
progressive increase with a surplus of $+10.2\%$ under
RCP4.5 and $+14.4\%$ under RCP8.5, while under RCP2.6 the
increase of potential yield during the same period will be
statistically not significant. The yield gap under RCP2.6
and RCP4.5 will fluctuate within a rather narrow range and
under RCP8.5, it will decrease},
