Rendimiento y productividad del agua en cultivos de invierno bajo riego deficitario

Tecnología y ciencias del agua
El riego deficitario es una estrategia para incrementar la productividad del agua especialmente en las zonas áridas y semiáridas. Con el objetivo de evaluar el efecto del riego deficitario (60, 80 y 100 de la evapotranspiración, ET) sobre el rendimiento ...

Phenological overlap between crop and pollinators: Contrasting influence of native and non‐native bees on raspberry fruits over the flowering season

Journal of Applied Ecology, Volume 60, Issue 12, Page 2540-2549, December 2023., 2023
Providing sufficient pollen and nectar resources to support wild pollinators over extended periods in agricultural landscapes can contribute to crop pollination and ensure high fruit weight and quality. This can be achieved by restoring natural and semi‐natural areas near crop fields with native, long‐flowering plant species.

Ecological and evolutionary effects of crop diversity decrease yield variability

Journal of Ecology, Volume 111, Issue 6, Page 1242-1253, June 2023., 2023
Results highlight the ecological and evolutionary role of plant interactions in crop mixtures, which can affect yield stability, while also reflecting on the importance of climate and resource availability in modifying the diversity‐stability relationship.

Global coordination of wheat sowing: A possible policy against climate variability

World Food Policy, Volume 9, Issue 1, Page 6-27, May 2023., 2023
Abstract Through an analysis of the sowing and harvesting times across all the regions of a tailored‐for‐wheat world geographic partition, we assess the temporal possibility of modifying the acreage of wheat crops in some regions in an attempt to offset the change in production caused by the El Niño Southern Oscillation (ENSO) in the others.

How seeds and growth dynamics influence plant size and yield: Integrating trait relationships into ontogeny

Journal of Ecology, Volume 110, Issue 11, Page 2684-2700, November 2022., 2022
Our results provide important insights into the proximal mechanisms that operate during ontogeny and drive variation in mature plant size in annual herbs. Of the three traits considered (a), seed mass and duration of vegetative growth had the greatest influence on plant size at maturity (b).

Multiple compensatory mutations contribute to the de‐domestication of Iberian weedy rice

PLANTS, PEOPLE, PLANET, Volume 4, Issue 5, Page 499-510, September 2022., 2022
Weedy plants are a major constraint on agricultural productivity. Weedy rice, a weedy type of rice, invades rice fields worldwide and is responsible for reductions in rice yields. Studies to date have detected multiple independent weedy rice origins in different parts of the world.

Flower strips and remnant semi‐natural vegetation have different impacts on pollination and productivity of sunflower crops

Journal of Applied Ecology, Volume 59, Issue 9, Page 2386-2397, September 2022., 2022
The implementation of flower strips or maintenance of remnant semi‐natural habitats adjacent to sunflower fields showed context‐dependent effects on pollinator visitation rates and crop yield. In highly simplified agroecosystems, these interventions may be insufficient or may need longer times to produce significant effects.
