Key Applications of L-Arginine

1. Nitrogen Metabolism Booster

• Enhances nitrogen assimilation, improving protein synthesis and overall plant growth.

2. Stress Resistance Enhancer

• Mitigates the effects of abiotic stresses like drought, salinity, and extreme temperatures by stabilizing cellular functions.

3. Root and Shoot Development

• Promotes cell division and elongation, leading to robust root systems and vigorous shoot growth.

4. Flowering and Fruit Set Improvement

• Increases the production of hormones like auxins and gibberellins, boosting flowering and fruit development.

Benefits of L-Arginine in Agriculture

1. Enhanced Nutrient Uptake: Facilitates the absorption of essential minerals.

2. Improved Yield Quality: Promotes better flowering, fruiting, and overall plant health.

3. Stress Tolerance: Helps plants adapt to environmental challenges.

4. Sustainable Farming: Reduces dependence on chemical fertilizers.

Application Guidelines

Foliar Spray

• Dosage: 2-4 mL per liter of water.

• Timing: Apply during vegetative and reproductive stages.

Soil Application

• Dosage: 10-20 mL per plant, diluted in water.

• Frequency: Every 15-20 days.

Seed Treatment

• Preparation: Soak seeds in a 1% L-Arginine solution for 6-8 hours before sowing.

Precautions

• Storage: Store in a cool, dry place, away from direct sunlight.

• Compatibility: Conduct a compatibility test before mixing with other agrochemicals.

• Application Timing: Avoid application during midday heat to prevent evaporation losses.
