Alfalfa response to low potassium under different harvest regimes in Coastal Plains

“…As expected, growth stage affected all forage nutritive value parameters. Although some variability was seen throughout the growing season, CP, TDN, and IVTDMD generally decreased as maturity increased (Table 4), congruent with the results reported by several other authors (i.e., Gasser et al., 1969; Kalu & Fick, 1983). Consequently, forage fiber components, NDF, ADF, and lignin increased (data not shown), similarly to Kallenbach, Nelson, and Coutts (2002) and Sheaffer et al.…”

“…The recent development of alfalfa cultivars well suited for this harsh climate has led to an increased interest in planting alfalfa in the region. It is well known that K fertilization and harvest timing both influence the productivity and longevity of an alfalfa stand (Berg et al., 2009; Gasser et al., 1969; Undersander et al., 2011); however, these management practices need to be examined further in the context of southeastern environments.…”

“…Potassium is a critical nutrient for many biological functions and affects overall plant performance (Grewal & Williams, 2002). Deficiencies of K are associated with increased disease, decreased photosynthetic ability, and reduced carbohydrate availability, all of which can negatively influence yield potential in alfalfa through winter kill or stand thinning (Amtmann, Troufflard, & Armengaud, 2008; Cooper, Blaser, & Brown, 1967; Peoples & Koch, 1979).…”

Effects of Early Summer and Fall Cutting Management on Dry Matter Yields, Digestibility, Crude Protein, and Survival of Saranac and Narragansett Alfalfas

“…Removal of the first cut at bud ments, average CP in cuts 2 and 3 was 14]9-stage with two, subsequent harvests at the early 77 .3 and li 3-19.4, respectively. IVD was bloom stage also allowed a total of three har- 54.5-60.7 in crft 2 and s6.0-aq.4 in cut 3. vests before early September Twamley (1960) recommended two to three cuts of alfalfa during the summer before the fall rest period. Folkins et al (1961), Langille et al (L965), and Gasser and Lachance (1969) In vitro digestibility of DM of alfalfa was determined from separate freczedried samples, using the method of rilley and rerry (1963) For personal use only. Langille et al (1965) and Gasser and Lachance (1969).…”
