Applications in Agriculture

PGRs are vital for helping crops withstand abiotic stresses such as drought, salinity, and extreme temperatures. For instance, a study on maize fields demonstrated that applying humates and other PGR-based treatments improved plant height, leaf surface area, and grain yield under adverse weather conditions. [1]

By targeting specific growth stages, PGRs enable farmers to optimize plant development. In horticulture, PGRs regulate flowering, prevent fruit drop, and enhance post-harvest quality. A review of ornamental crops highlighted their efficiency in increasing flower yield while minimizing environmental impact. [2]

Innovations in PGR formulations and delivery systems ensure targeted application, reducing resource waste. A comprehensive review in the Journal of Scientific Research and Reports explored advanced PGR technologies that improve stress tolerance and crop output through precision interventions. [3]

PGRs play a crucial role in reducing the dependence on chemical inputs, such as fertilizers and pesticides. By promoting efficient resource use, these regulators align with eco-conscious farming practices. Research trends emphasize the need for sustainable formulations and smart delivery systems to meet the demands of environmentally friendly agriculture. [4]

Despite their benefits, challenges remain in the widespread adoption of PGRs. These include the need for crop-specific formulations, cost considerations, and regulatory compliance. However, ongoing research is addressing these challenges, with promising advancements in biotechnology and agrochemistry poised to expand the utility of PGRs.
