Introduction

Weeds are the most damaging pest for yields in arable crops, as they compete with the crops for light, minerals and water (Oerke, 2006). Because of climate change, crop-weed competition for water is expected to increase.

As water use and crop-weed competition depend on plant morphology (Moreau et al., 2022), we investigated the interspecies diversity in morphological...

Psylliodes chrysocephala is among the main pests of oilseed rape in Europe and is mainly managed with insecticides. Increasing insecticide resistance and health and environmental concerns have highlighted the need for alternatives to chemical control, such as conservation biological control. Conservation biological control can be enhanced by (1) providing resources to beneficial organisms in...

Introduction
Agronomic studies on the use of intermediate wheatgrass (Thinopyrum intermedium) as a perennial grain crop show a grain yield decline over the years, which calls for a better understanding of the link between Th. intermedium vegetative development and investment in reproduction. Recent data suggest that density and row spacing might influence yield components in *Th....

Objectives:
Most arable lands in Mediterranean countries are located in arid and semiarid regions, where water and soil salinity, water shortage and nutrients deficiency in soils are the major constraints affecting food and fodder production. In this context, halophytes emerge as alternative cash crops to be used in sustainable saline production systems, due to their ability to cope with...

Introduction
Intercropping is a management practice inspired by the interaction between the biodiversity of an ecosystem and its resilience under stress. Intercropping is of strategic interest in the face of climatic and environmental issues, having already shown the capacity to bring beneficial outcomes on production and ecosystem services (for example Gardarin, A. et al, 2022). However...
