Seaweed extract is a natural substance that is derived from various plants and has the potential to provide numerous benefits as a plant growth regulator (PGR). This extract contains multiple bioactive compounds, such as antioxidants and phytohormones, which can influence plant growth and development positively. By promoting root growth, enhancing flowering and fruiting, and increasing crop yields, seaweed extract has demonstrated its potential as a PGR. Additionally, it can enhance a plant`s resistance to environmental stressors like drought, salinity, and temperature stress. The use of seaweed extract as a PGR also improves the nutritional value and quality of crops, making them more desirable to both consumers and producers. One of the most significant advantages of using seaweed extract as a PGR is its eco-friendliness. Since it is a natural substance, it poses no harmful impact on the environment and is entirely safe for human health. Moreover, by reducing the reliance on synthetic chemicals, the use of seaweed extract as a PGR can contribute to sustainable agricultural practices. Ongoing research into the benefits of seaweed extract as a PGR is revealing even more potential benefits. As we continue to learn more about its properties, it may become a valuable tool for promoting sustainable agriculture practices, increasing crop yields, and enhancing food security. Seaweed extract is a promising natural substance with numerous benefits as a PGR in various crops, making it an exciting area of study for researchers and growers alike. With its positive effects on crop yields, plant resistance, and environmental impact, it has the potential to become an essential tool for promoting sustainable agriculture practices.
