SW5637S

Dormancy 5 Alfalfa

SW5637S is a high-yielding, fall dormant variety, bred in saline growing conditions and selected for the ability to maintain improved production of hay in saline soils. Relative Feed Quality (RFQ) is above average, 102% of the mean versus RFQ of elite check varieties. SW5637S demonstrates very good yield retention in moderate to strong saline growing conditions.

Key Advantages
