Is alfalfa perennial or annual?
Alfalfa is a perennial – it is planted in the spring or fall and then harvested for many years. The seedbed is usually prepared finely to cover the seed, but some growers seed alfalfa without tillage, directly into stubble. Alfalfa seed must be planted close to the soil surface since it is very small (1-2 mm).
Do you have to reseed alfalfa every year?
Alfalfa is a crop that naturally tends to lessen its density over time because alfalfa doesn’t reseed itself. Planting more alfalfa into current alfalfa fields is not recommended since alfalfa has autotoxicity characteristics. A good population/density is about 35 well-growing stems per square foot.
Does alfalfa come back year after year?
Managing Seeding Year Alfalfa You can harvest seeding-year alfalfa as early as 40 days after seedlings emerge. It takes plants about 40 days to become able to regrow from the crown after cutting.
How often does alfalfa need to be replanted?
Alfalfa should never be replanted into the same field for at least one year due to the alleopathic effect of mature plants on development of new seedlings and minimal risk of disease for the new planting.
How long does alfalfa last?
Alfalfa can remain productive in stands from four to ten years or more, but as plant population declines renovation eventually becomes necessary.
Do farmers plant alfalfa?
These days, the top alfal- fa-producing states are in the West and Midwest; it can also be grown in the South on well-drained soils. It is no accident that the two top dairy states, California and Wisconsin, are also leading states in alfalfa production.
How many years will alfalfa last?
How many years will alfalfa grow?
Perenniality—The fact that the crop grows for 4-8 years, grows quickly with warm conditions in the spring is a major advantage of alfalfa—it can utilize residual winter rainfall before irrigation is necessary.
Does alfalfa regrow after cutting?
Alfalfa takes about 40 days to develop the ability to regrow from the crown after cutting. Plants cut before this point need at least one set of leaves remaining to regrow.
How many years can you plant alfalfa?
SHORT ANSWER: The most reliable amount of time to leave fields out of alfalfa before reestablishing is the number of years the stand lasted. If a stand lasted 6 years — leave it out for 6 years. Alfalfa can be replanted after alfalfa in the same year in some situations but is not recommended.
What month do you plant alfalfa?
If you have land available for alfalfa in late summer, optimal seeding dates are July 15 through August in the Upper Midwest; closer to July 15 for northernmost regions. For growers in warmer climates, seeding into early September is acceptable.
What is the best soil for alfalfa?
Alfalfa does well on well-drained soil rather than wet, heavy clay soils and requires good soil pH ranging from 6.5 to 7.0. If your soil pH is lower than 6.5, symbiotic nitrogen fixation may not function properly.
When to sow alfalfa?
Alfalfa planted in August establishes well when moisture is available. Be sure to plant early enough so alfalfa has 6 to 8 weeks between emergence and freeze back to develop good cold tolerance. That means that if you are in northern Nebraska or southern South Dakota, you need to plant in early August.
Where does alfalfa grow best in the US?
Alfalfa seed is primarily grown in the northwestern areas of the U.S. primarily in the states of California, Idaho, Nevada, Oregon, Wyoming, and Washington.
How long does it take alfalfa to flower?
The first harvest can be made before flowers begin to appear, but waiting for the alfalfa to flower will ensure greater energy reserves in the roots. Alfalfa will generally reach this stage of development between 60 and 70 days after emergence.
When can you plant alfalfa?
Alfalfa can be planted in both the fall and spring, but fall plantings have been much more successful in stand establishment and first year production yields. For S.E. Oklahoma, planting should take place from late Aug. through September.
