Crop Diversity Management System Commons: Revisiting the Role of Genebanks in the Network of Crop Diversity Actors [PDF]
Agronomy, 2021 This paper rethinks the governance of genebanks in a social and political context that has significantly evolved since their establishment. The theoretical basis for the paper is the commons conceptual framework in relation to both seed and plant genetic resources.

Crop Species Production Diversity Enhances Revenue Stability in Low-Income Farm Regions of Mexico
Agriculture, 2022 Stabilizing farm revenues is a goal of agricultural policies around the world, especially in vulnerable regions with limited access to crop insurance. One potential pathway to revenue stability follows the agricultural “insurance hypothesis”, which holds

Cover Crop Biomass Production Is More Important than Diversity for Weed Suppression [PDF]
, 2019 Biotic resistance theory suggests that diverse cover crop mixes may be more effective at weed suppression than a cover crop monoculture. However, evidence for this has so far been inconsistent.

Trap crop diversity enhances crop yield [PDF]
Agriculture, Ecosystems & Environment, 2016 Abstract Diverse plantings provide many benefits for agroecosystem health. For example, ⿿trap crops⿿ that are highly attractive to pests can protect nearby, less attractive host plants. However, it is unclear whether increasing biodiversity of trap crops themselves might increase the effectiveness of this pest-management technique.

Burial-induced changes in the seed preferences of carabid beetles (Coleoptera: Carabidae)
European Journal of Entomology, 2019 Seeds of many species of plants may survive for a long time in the soil and germinate when brought to the surface, but whether they are subsequently eaten by seed predators is unknown. We examined the preferences of three species of carabids (Coleoptera:

EVALUATION OF REGIONAL DIVERSIFICATION IN SOWN AREA STRUCTUREIN THE CONTEXT OF IMPACT ON THE NATURAL ENVIRONMENT [PDF]
Annals of the Polish Association of Agricultural and Agribusiness Economists, 2017 In recent years many important changes have taken place in Polish agriculture. The aim of the paperwas to determine the diversity of the structure of sown area in the voivodships and its potential impacton the natural environment.
