H. auteur aut IRD text journalArticle eng text/pdf born digital access We present work using two long-term climate datasets to show that nitrogen fertiliser is an important aspect of yield projection for three major crops. The ability of linear models using climate variables as predictors to accurately project the yield of maize, rice and wheat over multi-decadal scales is improved with the addition of fertiliser as an input. Highly productive nations including Argentina, India, Poland and South Africa show significant improvement in yield simulations and show that fertiliser use should not be discounted when estimating yield variability. The use of nitrogen fertiliser in the generalised linear models improves yield forecast by 18% using the Princeton climate dataset and 23% using the WFDEI climate dataset. This work therefore supports the use of additional predictors than climate for improving the ability of statistical models to reconstruct yield variability. specialized Fertiliser Statistical modelling Maize Rice Wheat 076 020 90 1-11 [+ Erratum paru Vo. 93, p. 135] 2017 1161-0301 https://www.documentation.ird.fr/hor/fdi:010071288 10.1016/j.eja.2017.06.012 1161-0301 [F B010071288] https://www.documentation.ird.fr/hor/fdi:010071288 https://www.documentation.ird.fr/intranet/publi/depot/2018-03-12/010071288.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2017-12-04 2023-07-11 fdi:010071288 fre
