Overview

Randomized trial evaluates effects of climate variability on Arabica coffee yield, suggesting improved resilience strategies are needed.

Key Points

  • The aim is to evaluate how climate variability affects the yield of Arabica coffee cultivars across different growth stages.
  • Evaluated several Arabica coffee cultivars over four phenological phases using yield-climate time-series data.
  • Applied Pearson's correlation coefficients and Mann–Kendall test to analyze climate and yield data.
  • Used historical yield data from 2011 to 2024 to validate an agrometeorological model at local and regional scales.
  • The grain-filling phase was most sensitive to rising temperatures, while flowering phases showed increased vulnerability.
  • Cultivar Bourbon Vermelho exhibited strong vegetative resilience but was notably susceptible during reproduction.
  • Yield losses were primarily linked to water deficits and cold events, with minimal effects from temperature increases.
