What To Know
- Use a grain drill or broadcast spreader to sow the alfalfa seed evenly at a rate of 20 to 25 pounds per acre.
- Allow the alfalfa to dry in the field until it reaches a moisture content of 15% to 20% before baling or storing.
Alfalfa, a highly nutritious and versatile forage crop, plays a crucial role in Oklahoma’s agricultural landscape. Known for its exceptional drought tolerance and high protein content, alfalfa is a valuable asset for livestock producers and hay growers alike. Planting alfalfa in Oklahoma requires careful planning and attention to specific agronomic practices to ensure a successful and productive crop. This comprehensive guide will provide you with step-by-step instructions, expert tips, and essential information to help you plant alfalfa in Oklahoma and achieve optimal yields.
1. Selecting the Right Variety
Choosing the right alfalfa variety is paramount to the success of your crop. Consider factors such as winter hardiness, disease resistance, yield potential, and specific management requirements. Opt for varieties that are well-adapted to Oklahoma’s climate and soil conditions. Consult with local agricultural extension offices or reputable seed suppliers for variety recommendations.
2. Preparing the Soil
Proper soil preparation is essential for successful alfalfa establishment. Begin by conducting a soil test to determine the pH level, nutrient content, and any potential deficiencies. Aim for a pH range between 6.5 and 7.0. If necessary, apply lime or sulfur to adjust the pH accordingly. Incorporate organic matter, such as compost or manure, to improve soil structure and fertility. Ensure adequate drainage to prevent waterlogging, which can harm alfalfa plants.
3. Planting Alfalfa Seed
The ideal time to plant alfalfa in Oklahoma is in the spring or fall when soil temperatures are moderate. Select a well-drained field with good soil fertility. Prepare the seedbed by disking or harrowing to create a fine, firm seedbed. Use a grain drill or broadcast spreader to sow the alfalfa seed evenly at a rate of 20 to 25 pounds per acre. Lightly cover the seeds with soil to ensure good seed-to-soil contact.
4. Managing Irrigation
Alfalfa requires regular irrigation, especially during the establishment phase and during periods of drought. Implement a consistent irrigation schedule to maintain adequate soil moisture levels. Avoid overwatering, as this can lead to root rot and other problems. Use efficient irrigation methods, such as drip or sprinkler systems, to minimize water usage and prevent runoff.
5. Fertilizing Alfalfa
Fertilization is essential for maintaining high alfalfa yields. Apply a balanced fertilizer blend containing nitrogen, phosphorus, and potassium according to soil test recommendations. Split the fertilizer applications into several smaller doses throughout the growing season to ensure a steady supply of nutrients. Consult with local agricultural extension offices or reputable fertilizer suppliers for specific fertilizer recommendations based on your soil conditions and alfalfa variety.
6. Controlling Weeds and Pests
Regular scouting and timely management of weeds and pests are crucial for maintaining a healthy alfalfa crop. Use integrated pest management (IPM) strategies to minimize the use of pesticides and herbicides. Implement cultural practices, such as crop rotation and proper irrigation management, to reduce pest pressure. If necessary, apply selective herbicides or pesticides to control specific weeds or pests.
7. Harvesting Alfalfa
The timing of alfalfa harvest is critical to ensure high-quality hay and maintain stand longevity. Monitor the crop closely and harvest alfalfa when it reaches the early bloom stage. This typically occurs 30 to 45 days after the first cutting. Use sharp cutting equipment to minimize plant damage and maintain a cutting height of 2 to 3 inches. Allow the alfalfa to dry in the field until it reaches a moisture content of 15% to 20% before baling or storing.
Tips for Successful Alfalfa Production in Oklahoma
- Choose a well-drained field with good soil fertility.
- Inoculate alfalfa seed with the appropriate Rhizobium bacteria to promote nitrogen fixation.
- Use a grain drill or broadcast spreader to sow the alfalfa seed evenly.
- Irrigate alfalfa regularly, especially during the establishment phase and during periods of drought.
- Fertilize alfalfa according to soil test recommendations.
- Control weeds and pests using integrated pest management (IPM) strategies.
- Harvest alfalfa when it reaches the early bloom stage.
- Use sharp cutting equipment and maintain a cutting height of 2 to 3 inches.
- Allow the alfalfa to dry in the field until it reaches a moisture content of 15% to 20% before baling or storing.
Harvesting Alfalfa
Alfalfa is typically harvested three to four times per year in Oklahoma. The first cutting is usually taken in late May or early June, with subsequent cuttings taken every 30 to 45 days. The final cutting is usually taken in late September or early October.
Baling Alfalfa
Once the alfalfa is dry, it is baled and stored. Alfalfa hay can be baled in square or round bales. Square bales are typically 14 inches by 18 inches by 36 inches, while round bales are typically 4 feet in diameter and 5 feet long.
Storing Alfalfa
Alfalfa hay can be stored in a barn, shed, or stack. The hay should be stored in a dry, well-ventilated area. Alfalfa hay can be stored for up to two years.
