L-Tryptophan is also called Tryptophan.It is L-type Amino Acid, it's essential for plants’ growth and development. It is natural Biostimulants which can be used to enhance the performance of crops. L-Tryptophan is a precursor to several plant hormones, including Auxins and indole acetic acid (IAA), which play a crucial role in plant growth and development. The use of L-Tryptophan as a biostimulant has gained significant attention in recent years due to its ability to improve plant growth, yield, and quality.The monomeric amino acid L-Tryptophan is popular in agriculture

What will plants benefit from L-Tryptophan?
1.Enhanced Growth: Tryptophan is an essential amino acid for plants’ growth and development. It helps in the formation of new tissues and cells, which results in the overall growth of the plant.
2. Increased Yield: Tryptophan plays a critical role in the production of plant hormones such as auxins, which are responsible for the growth and development of the plant. Increased levels of auxins can lead to higher yields of crops.
3. Stress Tolerance: Tryptophan can help plants to cope with stress caused by environmental factors such as drought, heat, or cold. It can increase the antioxidants level in plants, which protect them from oxidative stress.
4. Disease Resistance: Tryptophan can also help plants to resist diseases caused by pathogens such as bacteria, viruses, and fungi. It can activate the plant's defense mechanisms, making it less susceptible to infections.
5. Nutrient Uptake: Tryptophan can improve the absorption of nutrients such as nitrogen and phosphorus by plants. It can increase the efficiency of the plant's root system, allowing it to absorb more nutrients from the soil. This can result in healthier and more robust plants.
