Vegetative growth response of cotton plants due to growth regulator supply via seeds
Acta Scientiarum. Agronomy, 2015 The global cotton industry is distinguished by its numerous industrial uses of the plume as well as by high production costs. Excessive vegetative growth can interfere negatively with productivity, and thus, applying growth regulators is essential for ...

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

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 ...

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.)

Nitrogen rate optimization for irrigated cotton in Florida
Agronomy Journal, Volume 117, Issue 6, November/December 2025.Abstract For irrigated cotton (Gossypium hirsutum L.) in Florida, the current nitrogen (N) fertilizer recommendation is 67 kg N ha−1 and has not changed in the last 40 years despite changes in cultural practices and development of new varieties. A study was conducted at three locations to re‐evaluate cotton [Delta Pine 2038 B3XF (DP 2038)] response to ...
