Leaf economics and tissue turnover dynamics in four perennial C4 grasses

Agrosystems, Geosciences &Environment, Volume 9, Issue 4, December 2026.
Abstract Warm‐season perennial grasses are important components of pasture systems in the United States, yet their functional characteristics and relationships with productive attributes remain poorly understood. This study evaluated tissue flow dynamics and leaf economic traits in four C4 forage grasses: eastern gamagrass (Tripsacum dactyloides (L.) L.

Impact of cultural practices on two‐spotted spider mite (Tetranychus urticae Koch) infestation in tomato cultivation in the Central Rift Valley of Ethiopia

Crop, Forage &Turfgrass Management, Volume 12, Issue 2, December 2026.
Abstract The two‐spotted spider mite (TSSM; Tetranychus urticae Koch) is a major pest of tomato (Solanum lycopersicum L.), causing substantial yield and quality losses in Ethiopia and worldwide. The present study evaluated the impact of tomato branch pruning and trellising on TSSM populations and yield in the Central Rift Valley tomato production area ...

Enhancing spring green‐up of warm‐season turfgrasses through late‐winter scalping

Crop, Forage &Turfgrass Management, Volume 12, Issue 2, December 2026.
Abstract Rapid spring green‐up of warm‐season turfgrasses in the transition zone is often desired to improve early‐season turfgrass quality, thereby increasing the acceptance of these species in arid and semi‐arid climates. This study evaluated the effects of late winter scalping on spring green‐up speed in 41 cultivars of bermudagrass (Cynodon spp ...

Defoliation patterns on a mixture pasture of forage sorghum and Alexandergrass

Semina: Ciências Agrárias
Detailing the morphogenic characteristics of tropical species that form mixed pastures allows a broader view of plant-animal interactions. The objective of this study was to evaluate the intensity and frequency of defoliation in a mixed pasture of ...

Screening bermudagrass genotypes for improved forage production

Crop, Forage &Turfgrass Management, Volume 12, Issue 2, December 2026.
Abstract Cynodon is a diverse genus of great economic importance to the southeastern United States. However, the bermudagrass stem maggot (BSM; Atherigona reversura Villeneuve) is threatening bermudagrass (Cynodon spp.) throughout the region. Long‐term solutions require the development and release of BSM‐tolerant bermudagrass genotypes.

Sustained Livestock Grazing Enhances Soil Organic Carbon Storage in Sub‐Arctic Grassland

Global Change Biology Communications, Volume 1, Issue 4, December 2026.
We studied long‐term effects of grazing cessation on 34 grassland and heathland sites in Iceland. Grazing cessation was associated with lower SOC, nitrogen and root carbon in the top 10 cm of soil providing evidence for enhanced SOC in grazed land, showing that grazing is a climate change mitigation strategy.

Effect of Grazing Intensity and Frequency on Forage Accumulation and Agronomic Characteristics of Tropical Mixed Pastures

Grasses
This study evaluated combinations of defoliation frequencies and intensities to identify grazing strategies that optimize forage accumulation and morphological composition in mixed pastures of Marandu palisadegrass (Urochloa brizantha cv.

Seasonal dynamics and defoliation impact on herbage yield in aspen boreal habitats of Alberta

, 2003
Within the aspen boreal ecosystems, little information exists on the seasonal dynamics of available herbage and the effects of varying defoliation regimes on accumulated herbage growth and associated opportunities for animal production.

Multiple ortho‐mosaicking software pipelines produce comparable imagery‐derived wheat phenotypes

The Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Unmanned aerial systems (UAS) equipped with multispectral and RGB sensors offer valuable data for monitoring crop health and assessing disease severity. However, the wide range of available photogrammetric software complicates software selection for high‐throughput plant phenotyping.
