Spatiotemporal climatic signals in cereal yield variability and trends in Ethiopia.

The fixed effect of the year variable was positive and highly significant ( p < 0.001) across all four cereal crops (Table 3 ), indicating a consistent upward trend in yields due to non-climatic influences for 1995–2018 period.
