Renovating permanent pasture to replace existing cool-season perennial grasses with improved varieties has potential risk and reward. Improved grasses may increase long-term productivity, but these increases should offset costs associated with replacing an existing stand. We eliminated existing perennial grass stands with tillage and herbicides and sowed a mixture of improved orchardgrass and meadow fescue in 2006 on five Wisconsin farms that used a range of rotational grazing systems. Paddocks were also subject to either typical producer management or recommended agronomic management. Despite considerable farm-to-farm variation, annual forage yield of improved varieties was greater than that of existing grasses the next two years. The yield advantage of improved varieties was greater when managed according to recommended agronomic practices in 2007, but management had no effect in 2008. Forage nutritive value was not influenced by grasses or management at any time during the growing season. Our results suggest that renovation with improved grasses increases pasture productivity, but producers should also consider their management and pasture production goals before renovating.

Over the last several years, spike-tooth aerators have been promoted as a tool to increase yield of grass pastures and hayfields across the Southeast. A two-year research project was conducted at two locations in Tennessee to evaluate the effect of spike-tooth aeration on the yield of tall fescue (Festuca arundinacea Schreb.). At the East Tennessee Research and Education Center and the Middle Tennessee Research and Education Center tall fescue plots were aerated once, either in spring or fall. Plots were fertilized with N at 60 lb/acre at spring green-up and harvested when forage height reached 8 to 10 inch. Results from both locations showed that aeration had no effect on tall fescue yield.

Overseeding warm-season perennial grasses with cool-season annuals in the southeastern U.S. has many benefits. Because the growing seasons overlap in autumn, management practices to reduce the warm-season grass competition are necessary for early cool-season forage production. Cool-season forage production and distribution is dependent on species, seeding rates, and planting methods. Growing seasons also overlap in spring which delays spring recovery of the warm-season grass.

Alfalfa (Medicago sativa L.) growers wanting to maximize annual yields are often tempted to take an additional harvest in late autumn. Our overall objective was to determine if harvesting alfalfa an 'extra' time in late autumn impacts long-term yield and stand persistence. Averaged over five years, the net gain in yield for taking an additional harvest in late autumn was only 0.11, 0.25, and 0.40 tons/acre for alfalfa harvested every 28, 35, and 42 days during the growing season, respectively. Stand persistence was equal for all treatments. An economic analysis shows that the low net yields from a late-autumn harvest usually do not justify the added expense.
