Response of cereals to intercropping with non‐food crops in tropical and subtropical regions: A meta‐analysis

open access: yesAgronomy Journal, Volume 118, Issue 3, May/June 2026.
Abstract Intercropping cereals with non‐food intercrops (NFICs) provides a means to enhance cereal productivity while providing additional benefits such as improved soil health or forage production. We conducted a meta‐analysis to investigate the effect of NFICs on cereal yields, cereal nitrogen uptake, and striga (Striga spp.) infestation, using 874 ...

Evaluating the Adapt‐N model for dynamic nitrogen recommendation in Brazilian maize (Zea mays L.) systems

open access: yesAgronomy Journal, Volume 118, Issue 3, May/June 2026.
Abstract Several nitrogen rate recommendation methods have been developed to help farmers fertilize close to the economic optimum N rate (EONR). The objectives of this study were to (i) evaluate a dynamic method (Adapt‐N) for N rate recommendations for maize (Zea mays L.) in Brazil relative to EONRs determined specifically for each trial and (ii ...

Homoisoflavonoids—From Natural Specificity and Biosynthesis to Precision Health‐Promoting Mechanisms

open access: yesFood Frontiers, Volume 7, Issue 3, May 2026.
Homoisoflavonoids are rare flavonoids with a unique bi‐aromatic oxygen‐heterocyclic structure. This review synthesizes their structure–activity relationships in anti‐inflammatory, hypoglycemic, and anticancer contexts. By highlighting their specific natural distribution and outlining biosynthetic pathways, it provides a conceptual framework and ...

Preliminary Functional Group Patterns of Arthropods in a Maize Field and Adjacent Cultivated Refuge Strip in South Africa

open access: yesAustral Entomology, Volume 65, Issue 2, May 2026.
ABSTRACT Agricultural intensification is a major driver of global arthropod declines. Habitat management strategies, such as cultivated refuge strips (CRS), can counteract these effects by enhancing biodiversity, promoting conservation biological control and improving agroecosystem resilience.
