Influence of frequency and intensity of defoliation on production and morphological development of Panicum maximum Jacq. cv. Sabi

open access: yes, 1974
Severe defoliation (2cm height) at fortnightly intervals was extremely detrimental to foliage and root dry matter production. High intensity of defoliation appeared to be more detrimental than high frequency.

Minimising sunburn necrosis on Vitis vinifera L. ‘Riesling’ grapes by defoliation, photo- and thermal protection [PDF]

open access: yes
Sunburn on grapes has emerged as an economic concern in recent decades. The phenomenon can be attributed to climatic changes, characterised by elevated air temperatures and intense solar radiation, leading to increased crop failures as well as quality ...

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

open access: yesThe 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

open access: yesThe 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 ...

Biomass allocation, compensatory growth and internal C/N balance of Lolium perenne in response to defoliation and light treatments

open access: yes, 2016
Light environments can have a considerable influence on how plants respond to defoliation through influencing the biomass allocation patterns and internal C/N ratio.

Time course sensor‐based phenotyping can predict Ascochyta blight disease severity in Cicer species

open access: yesThe Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Ascochyta blight is a widely occurring chickpea fungal disease that can cause severe yield loss. Breeding for crop resistance benefits from high‐throughput evaluation of plant–pathogen interactions in genotypes which can serve as sources of resistance.

Reducing Costs and Optimizing the Timing of Agronomic Inputs for Cotton (Gossypium hirsutum L.) in North Carolina.

open access: yes, 2009
Cotton (Gossypium hirsutum L.) grown in North Carolina requires intensive management for achieving optimal yields in an early-season environment. Recent increases in production costs require cotton producers to adopt practices that allow yield potential

Genomic and phenomic prediction models improve selection accuracy for complex traits in alfalfa

open access: yesThe Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Predictive breeding has been proposed as an effective approach to accelerate genetic gain for complex traits. Genomic prediction (GP) models have been developed in alfalfa (Medicago sativa L.) for key traits in the last decade. More recently, phenomic prediction (PP) models have been proposed as a low‐cost, high‐throughput alternative to GP in

Effect of defoliation frequency and height of cutting on growth, dry matter yield and nutritive value of Napier grass (Pennisetum purpureum (L.) Schumach)

open access: yes, 2010
Growth characteristics, dry-matter (DM) yield, chemical components and in vitro dry-matter digestibility (IVDMD) of Napier grass were studied in a randomized complete block design with three replications at Haramaya University, Ethiopia.

Spodoptera litura (Lepidoptera: Noctuidae) Adult Abundance and Larval Host Plant Use in the Ord River Irrigation Area, Western Australia

open access: yesAustral Entomology, Volume 65, Issue 4, November 2026.
ABSTRACT Spodoptera litura (Fabricius) is a highly polyphagous lepidopteran pest; however, little is known about its seasonal population dynamics or larval host plant use in northern Australia. Improved understanding of the ecology of S. litura is increasingly important given the anticipated expansion of Bacillus thuringiensis (Bt) cotton production in
