Effect of Mepiquat Chloride on the Growth and Yield of ‘Concord’ Grapevines1

Journal of the American Society for Horticultural Science, 1982
Abstract Mepiquat chloride (MP-Cl) applied at the late prebloom stage or during bloom increased the set and yield of ‘Concord’ grape ( Vitis labruscana Bailey) and restricted length of pre-existing but not yet fully expanded internodes, but not those formed subsequent to ...

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 ...

Optimizing physiological performance, assimilate partitioning and productivity of late-sown wheat (Triticum aestivum L.) through mepiquat chloride application under nitrogen enrichment

Frontiers in Agronomy
IntroductionLate sowing constrains grain yield formation in wheat by shortening the duration of post-anthesis assimilate accumulation and limiting the effective utilization of source-derived assimilates during grain filling. Optimizing nitrogen nutrition

Seasonal variations in net ecosystem exchange of CO2 and conservation of water use efficiency of cotton in the Mississippi Delta

Agrosystems, Geosciences &Environment, Volume 8, Issue 2, June 2025.
Abstract Accurately quantifying the net ecosystem exchange (NEE) of CO2 is a critical prerequisite for developing alternative farm management strategies to enhance carbon sequestration in biological systems and reduce greenhouse gas emissions. A 2‐year study quantified the NEE of CO2 from cotton (Gossypium hirsutum L.) on silty clay in farm‐scale ...

Sensitivity Assessment of Varieties, Effectiveness of Weed Control by Selected Herbicides, and Infection of the Fusarium in Maize (Zea mays L.) Cultivation

Agronomy, 2020
The amount of maize yield depends on many factors. Among them, plant health plays a significant role. Herbicide selectivity (of mesotrione, 2,4-D, and bromoxynil) for different maize varieties was assessed in greenhouse experiments.

Integrating cover crops and targeted herbicide applications in cotton production

Agrosystems, Geosciences &Environment, Volume 8, Issue 2, June 2025.
Abstract Cover crops are part of integrated weed control management to help mitigate herbicide resistance evolution. Targeted sprays from the John Deere See & Spray are currently not recommended in cover crops. Experiments were conducted yearly from 2022 to 2024 in Keiser, AR, to evaluate targeted applications (TAs) with cover crops in cotton ...
