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.

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 ...

COIRÓN DULCE (Festuca gracillima Hook, f.) GROWTH PHYSIOLOGY UNDER DIFFERENT DEFOLIATION INTENSITY LEVELS AND WATER RESTRICTION REGIMES [PDF]

Festuca gracillima Hook, f. is a tussock grass species that grows and dominates the rangelands of the Magellan Region in Chile. It may exhibit tolerance to water restriction, while low defoliation intensity could encourage F. gracillima growth regardless

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.

Rough Fescue Response to Season and Intensity of Defoliation

, 1985
Rough fescue (Festuca scabrella Torr.) was subjected to 10 clipping regimes which varied in time or intensity of defoliation. The experiment was repeated at 2 sites for 3 consecutive years.

Developing and deploying an unmanned aerial system–based phenotyping program for maturity to support soybean breeding

The Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Soybean [Glycine max (L.) Merr.] varieties are categorized into different relative maturity groups (MGs) that correspond to the approximate region that the variety is best adapted. Maturity is an important trait that growers consider when deciding which varieties to plant and for breeders as a covariate to compare genotypes.

Pixel‐level supervision resolves overlap: Benchmarking YOLOv12 segmentation for accurate multi‐cluster dry bean stand counting from time series unoccupied aerial systems imagery

The Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract An agronomic trait such as stand count is important for cultivar development and crop management practices. Manually counting the number of plants is time consuming, labor‐intensive, and prone to error. The use of unoccupied aerial systems (UAS)‐collected red, green, blue (RGB) imagery in conjunction with advanced deep learning and image ...
