  1. Using PEAQ to Estimate Alfalfa NDF for Multiple Cuttings

    Author(s): Rory Lewandowski, CCA , Author(s): Mark Sulc

    Much of the region’s alfalfa crop has been harvested over the past two weeks.  As cooler temperatures move into the area regrowth will likely slow down. Once regrowth reaches 16 inches tall again, the NDF (neutral detergent fiber crude protein) can rapidly be estimated in the field using the predictive equations for alfalfa quality (PEAQ).

  2. Alfalfa First Cutting NDF Update

    Many hay fields in the region were harvested last week where drying conditions were good. Harvesting will continue into this week if the weather window remains open. The table below reports average neutral detergent fiber (NDF) values from different fields of alfalfa in each county listed. NDF values increased 5 - 6.5 percentage units when compared to last week’s NDF values. Grass fiber would have increased even more, as most hay grass species are fully headed.

    Estimating Fiber Content of Alfalfa in the Field

    Author(s): Rory Lewandowski, CCA , Author(s): Mark Sulc

    Additional Author: Angela Arnold

    Alfalfa stands in Ohio had a slow start this spring, but our recent change in weather is causing alfalfa development to move quickly. Stand growth is catching back up to where it would normally be at this time of year. As we approach the end of May many producers will be making harvest decisions.

    It is common for many growers to base harvest decisions primarily on alfalfa maturity; however, variable weather conditions affect the rate of bud and flower development in alfalfa and this method can be inaccurate.
