Many factors influence successful forage productionbut establishment of the crop is a key to profitability. It is essential to choose the appropriate crop species for the needed yieldqualityand persistence.

It is then critical to choose a variety that is recommended for one’s area. (Find more information on which forage species is appropriate for the need and a list of recommended varieties for the selected species at www.alabamaforages.com.)

Attention to other factors that affect successful stand establishment and yield is also important. Select high- quality seed that meets or exceeds recommended levels of germinationpurityand weed seed contamination. Ensure that the seed is planted at the right ratedepthand time of the year. Additionallyensure that seeding method and planting environment are appropriate to the species too. Also ensure that the seed is either pre-inoculated or that it is inoculated with the correct inoculant group.

The planting operation is when producers most often make yield-reducing mistakesso take time to minimize these errors. This planting guide has been developed to help producers in establishing most forage legumes commonly grown in Alabama. Information provided about a given forage species is not necessarily a recommendation to grow that species but rather is for information only. Some commonly grown forage legumes are not recommended by Auburn University. Some varieties of given species may also produce well in certain areas while others may not. This guide simply offers the information needed to have the best chance of establishing a forage legume speciesif a producer so chooses.

Five Steps to Higher Yields and More Profit

1. Test

  • the soil to determine nutrient needs. (Send soil samples to be analyzed at a certified diagnostic labsuch as the SoilForageand Water Testing Laboratory at Auburn University.)
  • Apply lime and fertilizer at levels appropriate to soil test result recommendations.

2. Seed

  • with goodhigh-quality seed and good seeding techniques.
  • with certified seed for added assurance of high seed quality.
  • with treated seedwhen possibleto protect against insect pests and disease.
  • with inoculants specific to the legume being planted.

3. Plant

  • with a goal of perfect stands!
  • at the proper depth in a properly prepared seedbed or no-till environment.
  • at the proper timewhen soil temperature is adequate and moisture is appropriate.
  • at the correct seeding rate per acre.

4. Manage

  • for high yields!
  • pests (weedsinsectsand diseases) to ensure that the plant is competitive in establishing and maintaining a good stand.
  • to maintain proper soil fertility throughout the life of the stand.
  • grazing to best utilize forage potential.

 5. Harvest

  • for high-quality yields!
  • at the right time.
  • with appropriate equipment that has been properly adjusted.

Exercise good handling and storage techniques to protect forage quality.

When buying inoculantsbe sure that the legume species you want to plant is listed on the package. All inoculants are not created equal and are species specific. Apply fungicide/fertilizer or other seed treatments at least 48 hours before planting; inoculate at planting. Remember (1) not to inoculate and treat legumes with fungicides at the same timeand (2) not to inoculate legume seed with fertilizer. Note: Presented pH values are a range and may not represent the ideal pH of planting.
