Quantifying the effects of irrigation, nitrogen application rate, and plant growth management on seed characteristics and seed component yields in cotton

Crop Science, Volume 66, Issue 4, July/August 2026.
Abstract Cotton (Gossypium hirsutum L.) growth and production are affected by irrigation management approaches, nitrogen (N) application rates, and plant growth regulation strategies. However, their combined effects on cotton seed composition and yield remain understudied.

Mepiquat chloride and paclobutrazol in size reduction of Arundina graminifolia

Agronomy Science and Biotechnology, 2017
The objective of this study was to evaluate the effect of mepiquat chloride and paclobutrazol on reducing the size of Arundina graminifolia for commercialization as a flower vase. The experiment was conducted in a greenhouse with 50% of shading. Plants were grown in one-liter black polypropylene vase filled with commercial substrate Plantmax ® and sand

The 2024 European Union report on pesticide residues in food

EFSA Journal, Volume 24, Issue 5, May 2026.
Abstract Under European Union legislation (Article 32, Regulation (EC) No 396/2005), the European Food Safety Authority publishes an annual report assessing pesticide residue levels in food. In 2024, 9842 samples were analysed as part of the EU‐coordinated multiannual control programme subset, of which 1.2% were found to be non‐compliant.

Biochemical and metabolic responses of cotton variety XLZ54 to Thrips tabaci and screening of resistance characterization indicators

Pest Management Science, Volume 82, Issue 2, Page 1656-1667, February 2026.
Cotton varieties resistant to Thrips tabaci exhibit lower soluble sugar and free amino acid levels, with smaller post‐infestation increases in these nutrients, resulting in reduced feeding rates and lighter damage. Key resistance evaluation indices include: damage severity, soluble sugars, free amino acids, soluble proteins, superoxide dismutase ...

The optimization of crop response to climatic stress through modulation of plant stress response mechanisms. Opportunities for biostimulants and plant hormones to meet climate challenges.

New Phytologist, Volume 249, Issue 1, Page 130-151, January 2026.
Summary This review discusses the use of agronomic management practices to enhance crop stress resilience to climate stress through the modulation of natural plant growth regulatory pathways. The use of biostimulants or plant hormones to improve crop resilience is subject to strict regulatory oversight if changes in the regulation of plant growth are ...

Hyperspectral reflectance‐based partial least squares regression models for predicting cotton leaf physiological traits

The Plant Phenome Journal, Volume 8, Issue 1, December 2025.
Abstract Alterations in the mechanistic drivers of photosynthesis have the potential to improve crop productivity, but their measurement is inherently time‐consuming using traditional methods. High‐throughput approaches to estimate photosynthesis using hyperspectral reflectance could be developed by leveraging variation in cotton (Gossypium hirsutum L.)
