Late summer seeding is an excellent way to establish stands and is actually the preferred time of year to seed in many regions. But your decision to late summer seed should be based on weather conditions (temperature), available soil moisture, and your projected forage needs (importance of having a fully productive alfalfa stand available next spring vs. direct seeding).
Aphanomyces root rot (ARR) is a serious disease of both recently seeded alfalfa and established alfalfa stands. ARR can cause severe yield reductions in affected alfalfa fields. Variations of the disease also occur on many other legumes (including soybean, snap bean, faba bean, red kidney bean, pea, red clover, and white clover) and can cause significant losses in these crops as well.
Stress in the seeding year reduces future yields of alfalfa. This occurs because the seeding year determines the stand plant density as well as individual plant size and vigor. The following paragraphs will show that autotoxicity, potato leaf hopper, cover crop, and, possibly, drought stresses in the seeding year will reduce alfalfa yield in future years, even when the stress is gone.
The decision to take a late summer or fall cutting of alfalfa should be considered carefully. A farm should evaluate current forage needs, economics, stand health, and timing to make the best decision for their individual situation. Although the need for more forage may override some other factors, the timing of harvest is still critical. […]
While farming in the ‘North’ brings the benefits of growing some of the best forages like alfalfa and cool-season grasses, it also carries the weight of fall decisions that will ‘make or break’ your profit due to risks of winter injury. Fall decisions regarding alfalfa production include proper harvest timing and providing adequate potassium, leading to strong plants that can survive a severe winter and come back the following year with good yield potential.

We have paid little attention to Pure Live Seed (PLS) in the Midwest because we have generally had high quality seed (greater than 90% germ and 98% purity). But the short forage seed supply has caused some low quality seed to come on the market. To avoid being caught paying market price for low quality […]
