Effect of climate change on rainfed herbaceous crops
Herbaceous crops in Mediterranean dryland environments face a great challenge for survival in the scene of climate change. The intensification of water deficits and the most frequent high temperature events during the late spring (April-June), coinciding with the grain filling stage of many species,...

| description | Herbaceous crops in Mediterranean dryland environments face a great challenge for survival in the scene of climate change. The intensification of water deficits and the most frequent high temperature events during the late spring (April-June), coinciding with the grain filling stage of many species, leads to continuous yield losses. In the Experimental Farm La Higueruela (Toledo, Spain), located in a typical Mediterranean agricultural environment of the Spanish dry land, it is analyzed how different meteorological variables are affecting cereal, chickpea, sunflower and vetch crops under conventional and ecological management. For this purpose, two long-term experiments (27 years) have been carried out, conventional end ecological managements, in which four crop rotations have been tested: Barley-Barley (CC), Barley-Chickpea (C-GAR), Barley -Sunflower (C-GIR), Barley-Vetch forage (C-VF). The results indicated that the meteorological variables that have registered a greater increase over time during the trial period are the average annual temperature of the agricultural year and those corresponding to the summer months, with the precipitation recorded during the month of May, as well as the frost period, the variables that have suffered the highest decrease. The most negatively affected crops were chickpea and sunflower in both agricultural managements and barley in organic farming, while the forage vetch would be favored in these conditions, especially in ecological management, due to its cultivation period. |

Los cultivos herbáceos en ambientes mediterráneos de secano se enfrentan a un gran desafío por la pervivencia ante el cambio climático. La intensificación de los déficits hídricos y los eventos más frecuentes de alta temperatura durante finales de la primavera (abril-junio), coincidiendo con la etapa de llenado del grano de muchas especies, producen pérdidas medias continuas de rendimiento. En la Finca Experimental La Higueruela (Toledo, España) ubicada en un entorno agrícola mediterráneo típico del secano español, se analiza cómo diferentes variables meteorológicas están afectando a los cultivos de cereal, garbanzo, girasol y veza en manejos convencional y ecológico. Para ello se han utilizado dos experimentos de larga duración (27 años), uno con manejo convencional y otro con ecológico, en los que se han ensayado cuatro rotaciones: Cebada-Cebada (C-C), Cebada-Garbanzo (C-GAR), Cebada-Girasol (C-GIR), Cebada-Veza forraje (C-VF). Los resultados indicaron que las variables meteorológicas que han registrado un mayor aumento con el tiempo durante el periodo del ensayo son la temperatura media anual del año agrícola y las correspondientes a los meses estivales, siendo la precipitación registrada durante el mes de mayo, así como el periodo de heladas, las variables que más han disminuido. Los cultivos más afectados negativamente fueron el garbanzo y el girasol en ambos manejos y la cebada en ecológico, mientras que la veza forraje se vería favorecida en estas condiciones, especialmente en manejo ecológico, debido a su ciclo de cultivo.
