Ecological correlates of crop yield growth and interannual yield variation at a global scale
Artificial selection and genetic engineering plus an expanding repertoire and use of agrochemical inputs have allowed a rapid and continuous increase in crop yield (i.e., volume production per unit area) over the last century, which is needed to fulfill food demands from a growing human population....

| description |
Artificial selection and genetic engineering plus an expanding repertoire and use of agrochemical inputs have allowed a rapid and continuous increase in crop yield (i.e., volume production per unit area) over the last century, which is needed to fulfill food demands from a growing human population. However, the first signs of yield deceleration and stagnation have already been reported for some globally important crops. There- fore, the study of the drivers of yield growth and its variation is essential for directing research and policies aiming at ensuring food security in the forthcoming years. We used data on mean and variability in annual yield growth for 107 globally important crops to assess the role of environmental (i.e., climatic region) and plant intrinsic traits (i.e., type of harvested organ, pollinator dependence, and life form) as drivers of change in yield growth and its stability. We applied a comparative approach to control for biases associated with phylogenetic non-independence among crops, an approach rarely used in agronomic studies. Average yield growth and its variation were not phylogenetically structured. Yield growth decreased with increasing pollinator dependence in tree crops but not in herbaceous and shrubby crops. Interannual yield variation tended to increase with in creasing pollinator dependence, and it was higher in crops from temperate regions, in those cultivated for their reproductive organs, and in tree and shrubby crops as compared with herbaceous ones. Information on ecological correlates of crop yield growth and interannual yield variation can be used in the design of more sustainable and diversified agriculture schemes. |

Selección artificial e ingeniería genética más un repertorio en expansión y uso de agroquímicos insumos han permitido un aumento rápido y continuo en el rendimiento de los cultivos (es decir, el volumen de producción por unidad de superficie) durante el siglo pasado, que se necesita para satisfacer las demandas de alimentos de una población humana en crecimiento. Sin embargo, la primera Ya se han informado signos de desaceleración y estancamiento del rendimiento para algunos cultivos de importancia mundial. Allá por lo tanto, el estudio de los impulsores del crecimiento del rendimiento y su variación es esencial para dirigir la investigación y las políticas con el objetivo de garantizar la seguridad alimentaria en los próximos años. Usamos datos sobre la media y la variabilidad en el rendimiento anual crecimiento de 107 cultivos de importancia mundial para evaluar el papel del medio ambiente (es decir, la región climática) y de la planta rasgos intrínsecos (es decir, tipo de órgano recolectado, dependencia del polinizador y forma de vida) como impulsores del cambio en el rendimiento crecimiento y su estabilidad. Aplicamos un enfoque comparativo para controlar los sesgos asociados con filogenética la no independencia entre cultivos, un enfoque raramente utilizado en estudios agronómicos. El crecimiento medio del rendimiento y su variación no estaban filogenéticamente estructurados. El crecimiento del rendimiento disminuyó con el aumento de la dependencia de los polinizadores en cultivos arbóreos pero no en cultivos herbáceos y arbustivos. La variación interanual del rendimiento tendió a aumentar con la aumentando la dependencia de los polinizadores, y fue mayor en cultivos de regiones templadas, en aquellos cultivados por su órganos reproductivos, y en cultivos arbóreos y arbustivos en comparación con los herbáceos. Información sobre ecológico Los correlatos del crecimiento del rendimiento de los cultivos y la variación interanual del rendimiento se pueden utilizar en el diseño de sistemas más sostenibles y sostenibles esquemas de agricultura diversificada.
