Sowing and Alfalfa Seeding Rate


Sowing and Seeding Rate of Alfalfa

Alfalfa seeds can be sown during autumn or spring. It is more common to sow on spring. We need about 40-60 kg of raw seeds per hectare. Keep in mind that if the seed that you have purchased is not raw (as the nature provides it) and has rather been treated, you have to ask your supplier about the exact seeding quantity per hectare, because it may differ significantly. Treated seeds are usually pre inoculated with rhizobium bacteria. Be sure to select quality seed that has been purified and cleaned from other weeds seeds, because otherwise your plants will suffer and underperform due to the weeds’ competition.

Raw versus treated alfalfa seeds


Alfalfa seeds are sown in rows using sowing machines that are attached to tractors. The sowing depth is 1/4 inch (0,6 cm). The distance between rows is normally 8 inches (20cm). About a week after the sowing, you will probably see the first sprouts. About two weeks after sowing, you will normally be able to count 15-25 new plants on average per square ft. If you cannot count more than 8-10 plants per square ft., you may have to consider plowing the field and sowing again. Many farmers add a phosphorus fertilizer in the alfalfa sowing machine, because any phosphorus deficiency will inhibit alfalfa’s root development.
