Growing High Value, High Yielding Lucerne

Introduction

This tutorial provides essential guidance on growing high-value and high-yielding lucerne (alfalfa), based on insights from agronomist Kyle Ropa. Lucerne is a nutritious forage crop that can significantly enhance livestock productivity. By following these steps, you can optimize your lucerne cultivation for better yields and quality.

Step 1: Selecting the Right Variety

• Choose a lucerne variety suited for your local climate and soil type.
• Consider factors such as:
  • Drought tolerance
  • Disease resistance
  • Yield potential
• Consult local agronomic resources or seed suppliers for recommendations.

Step 2: Soil Preparation

• Conduct soil testing to assess pH, nutrient levels, and organic matter content.
• Amend the soil based on test results to ensure optimal growing conditions:
  • Lime to adjust pH if necessary (ideal pH is 6.5 to 7.5).
  • Add fertilizers to boost nutrient levels, particularly phosphorus and potassium.
• Prepare a seedbed that is fine and firm to promote seed-to-soil contact.

Step 3: Seeding

• Time your seeding for optimal growth, typically in spring or early fall.
• Follow these seeding guidelines:
  • Use a seed drill or broadcast method, ensuring seeds are planted at a depth of 1-2 cm.
  • Aim for a seeding rate of about 10 kg per hectare (or adjust based on variety).
• Ensure good soil moisture to facilitate germination.

Step 4: Irrigation Management

• Monitor soil moisture levels regularly.
• Implement irrigation as needed, especially during dry spells:
  • Apply water to maintain consistent moisture, especially during establishment.
• Avoid waterlogging, which can lead to root rot and other issues.

Step 5: Weed Control

• Implement a weed management plan to minimize competition:
  • Use pre-emergent herbicides before seeding.
  • Employ mechanical methods, such as mowing, during the early growth stages.
• Regularly monitor for new weed growth and address it promptly.

Step 6: Fertility and Nutrient Management

• Develop a fertilization schedule based on plant growth stages:
  • Apply nitrogen, phosphorus, and potassium as needed.
• Consider using foliar feeds during critical growth periods to enhance nutrient uptake.

Step 7: Pest and Disease Management

• Regularly scout for pests and diseases.
• Implement integrated pest management (IPM) strategies:
  • Use resistant varieties.
  • Apply organic or chemical treatments as necessary.
• Keep records of any treatments for future reference.

Conclusion

By following these steps, you can successfully grow high-value and high-yielding lucerne. Remember to continuously monitor soil health, manage irrigation wisely, and stay proactive with weed and pest control.
