Dormancy 6 Alfalfa
A high-yielding, moderately dormant variety of alfalfa with resistance to bacterial wilt, Fusarium wilt, Anthracnose, Phytophthora root rot, spotted alfalfa aphid, pea aphid and southern root knot nematode, SW 6330 is also moderately resistant to blue alfalfa aphid and stem nematode.
Adaptation and Appearance
SW 6330 is a high-yielding variety, with a fall dormancy rating of 6. After four harvest years at the New Mexico Agricultural Science Center (Clovis, New Mexico), this variety was rated 100% for stand persistence in a clay soil. SW 6330 is adapted to the Southwest and Great Plains regions of the United States. The mid-summer and fall growth is erect, recovers rapidly after cutting, and produces well in climate areas suited to a dormancy of 6 rating.
SW 6330 topped the three-year yield trial conducted by the University of New Mexico at its Artesia field station. It also did very well at Clovis, New Mexico and at Davis, California in university yield trials.
This variety gives California, Arizona and New Mexico hay growers and dairymen a good yielding variety with the feeding quality of a moderately dormant alfalfa. Its stand persistence is excellent.
