Alfalfa performs admirably an irrigated crop in South Dakota-so well that it is often neglected. When given attention, it can realistically maintain irrigated yields of 6 to 7 TIA each year in most of South Dakota where 1 to 2 T are produced on dryland. Irrigated land that will produce 100-130 bu corn will produce 5-7 T alfalfa. On poorer irrigated land that produces 50-70 hu corn, one can expect 3-5 T alfalfa. Alfalfa has higher water requirements for peak yields than most other crops. It may not reach its full potential yield in any part of the stale without …
