Alfalfa, also known as Lucerne, is a highly nutritious and versatile forage crop prized for its exceptional yield and protein content. Whether you’re a seasoned farmer or just starting, learning how to grow good alfalfa is essential for maximizing your harvest and reaping the benefits of this remarkable crop. This comprehensive guide will take you through the necessary steps, from selecting the right variety to harvesting and storing your alfalfa.
1. Choosing the Right Variety
The first step in growing good alfalfa is selecting the right variety for your specific needs and growing conditions. Consider factors such as climate, soil type, intended use (grazing, hay, silage), and pest and disease resistance. Some popular varieties include:
- Vernal: A high-yielding variety known for its winter hardiness and resistance to alfalfa weevil.
- Ranger: A versatile variety with good yield potential and resistance to common diseases.
- WL 354HQ: A high-quality variety with improved forage quality and resistance to aphids and stem nematodes.
2. Preparing the Soil
Alfalfa thrives in well-drained soils with a pH between 6.5 and 7.5. If your soil is acidic, you may need to apply lime to raise the pH. Additionally, ensure your soil has adequate levels of phosphorus, potassium, and sulfur. Conduct a soil test to determine the specific nutrient requirements of your field.
3. Planting Alfalfa
The optimal time for planting alfalfa varies depending on your location and climate. In general, spring planting is preferred in cooler regions, while fall planting is better suited for warmer areas. When planting, use high-quality seed with a germination rate of at least 85%. Plant the seeds at a depth of 1/4 to 1/2 inch and a rate of 20 to 30 pounds per acre.
4. Managing Water and Nutrients
Alfalfa requires regular irrigation, especially during dry spells. Aim for 1 to 2 inches of water per week, either through rainfall or irrigation. Fertilize your alfalfa crop according to soil test recommendations and the specific needs of your variety. Nitrogen fertilization is typically not required, as alfalfa can fix its own nitrogen from the atmosphere.
5. Controlling Weeds, Pests, and Diseases
Regular scouting is crucial for identifying and managing weeds, pests, and diseases that can affect your alfalfa crop. Common weeds include foxtail, pigweed, and lambsquarters. Control weeds through cultivation, herbicides, or a combination of both. Common pests include alfalfa weevil, aphids, and grasshoppers. Manage pests by using biological controls, insecticides, or a combination of both. Common diseases include bacterial wilt, verticillium wilt, and leaf spot. Control diseases by using resistant varieties, crop rotation, and fungicides.
6. Harvesting and Storing Alfalfa
The timing of your alfalfa harvest depends on the intended use. For hay, cut the crop when the plants are in the early bloom stage. For silage, cut the crop when the plants are in the late bud stage. For grazing, allow livestock to graze the crop when the plants are 8 to 12 inches tall. After harvesting, cure the alfalfa hay properly to prevent spoilage. Store the hay in a dry, well-ventilated area to maintain its quality.
7. Maintaining Alfalfa Stands
Alfalfa stands can last for several years with proper management. To maintain a healthy stand, follow these tips:
- Rotate your alfalfa crop with other crops to break pest and disease cycles.
- Control weeds, pests, and diseases promptly to prevent them from spreading.
- Fertilize your alfalfa crop according to soil test recommendations.
- Irrigate your alfalfa crop regularly, especially during dry spells.
- Harvest your alfalfa crop at the proper stage of maturity.
Reap the Rewards of Growing Good Alfalfa
By following these steps, you can successfully grow good alfalfa and enjoy the benefits of this valuable crop. Alfalfa is a highly nutritious and versatile forage that can be used for grazing, hay, silage, and even as a green manure. With proper management, you can achieve high yields and maximize the profitability of your alfalfa operation.
