Extended Data Table 5 Influence of crop diversity and mean weather on national caloric yield stability, mean and temporal variation

From: National food production stabilized by crop diversity

  1. Results for multiple linear regression models using non-standardized predictor variables (n = 437). a, A regression using effective crop group diversity. b, A regression using effective crop species diversity. Yield stability, μ and σ were log-transformed and the rate of nitrogen fertilization and irrigation were square-root-transformed. *P < 0.05; **P < 0.01; ***P < 0.001.
