UAV‐based RGB and multispectral vegetation indices as alternatives to light box‐derived dark green color index for turfgrass color assessment

open access: yesThe Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Traditionally, turfgrass color has been assessed through visual ratings or light box‐based digital image analysis, methods that are either subjective or labor‐intensive. In this study, we evaluated the potential of unmanned aerial vehicle (UAV)‐based multispectral and red‐green‐blue (RGB) imagery as a high‐throughput alternative for capturing ...

Peanut response following soybean grown full‐season or double‐cropped after wheat in North Carolina

open access: yesCrop, Forage &Turfgrass Management, Volume 12, Issue 1, June 2026.
Abstract Including soybean [Glycine max (L.) Merr.] in the previous cropping cycle can adversely affect peanut (Arachis hypogaea L.) yield by increasing disease incidence and populations of plant‐parasitic nematodes in the soil. The impact of double‐cropping wheat (Triticum aestivum L.) and soybean versus full‐season soybean (referred to as the soybean

Validation of a portable near‐infrared reflectance spectrometer to determine harvest maturity in grass seed crops

open access: yesCrop, Forage &Turfgrass Management, Volume 12, Issue 1, June 2026.
Abstract Seed moisture content (SMC) is the most reliable indicator of seed maturity and the optimal harvest timing in grass seed crops. Current SMC testing methodologies used in grass seed crops are slow or inaccurate, making it difficult to make timely harvest decisions.
