“…Historically, alfalfa in the southeastern United States was limited, mainly because of compacted acidic soils high in aluminum, which limit root growth and stand persistence (Hoveland et al., 1988). However, the adoption of alfalfa in the southeastern United States as a monoculture or as a companion crop with bermudagrass ( Cynodon dactylon L.) is on the rise (Brown & Byrd, 1990; Missaoui & Young, 2016; Stringer, Khalilian, Undersander, Stapleton, & Bridges, 1994; Stringer, Morton, & Pinkerton, 1996). Hay and livestock producers are attracted to alfalfa because of its high nutritive value, N fixation ability, and the availability of newly developed cultivars that are tolerant to pests, grazing, and environmental conditions that have, in the past, restricted production (Bouton & Gates, 2003).…”

“…These application rates are intended to supply 150 to 250 lb N acre −1 . In grass hay production, N needs are normally three to four times higher than P requirements, where continuous application of PL leads to accumulation of P in the soil and subsequent loss into the environment (Missaoui & Young, 2016). Legumes can remove greater amounts of N, P, and K than some grasses and are beneficial in removing nutrients from pastures or hay fields where prolonged use of PL has contributed to high or toxic soil test levels of specific nutrients (Pederson, Brink, & Fairbrother, 2002).…”

Alfalfa (Medicago sativa L.) production in the Coastal Plain of the southeastern United States requires enhanced soil fertility management to capitalize on increased dry matter yield and nutritive value. Poultry litter (PL) is an abundant fertilizer source that has been recognized as an economical choice for pasture and hay production. A field trial was established in east‐central Mississippi in which PL and inorganic fertilizer sources were compared in three alfalfa cultivars in 2018 and 2019. Fertilizer treatments included (a) 2 ton PL acre−1 (Treatment 1); (b) 4 ton PL acre−1 (Treatment 2); (c) inorganic N, P, and K delivered at similar rates to Treatment 1; and (d) inorganic P, and K (no N) supplied at same rates as Treatment 3. The cultivars were Bulldog 505, Bulldog 805, and AlfaGraze 600RR. Forage mass (FM), plant persistence (PER), nutritive value [crude protein (CP), total digestible nutrients (TDN), and relative forage quality (RFQ)], and economic comparisons were conducted. Repeated measures analysis observed no differences between cultivars or treatments for FM, PER, or CP. Bulldog 505 had superior TDN and RFQ values for 7 out of 11 total harvests. Plots with applied PL (2 or 4 ton acre−1) recorded greater TDN values than inorganic sources in 4 of 11 harvests. In 2018, Bulldog 505 produced the lowest cost per ton ($96.29 ton−1); in 2019, similar costs were observed between Bulldog 505 ($147.57 ton−1) and Bulldog 805 ($147.96 ton−1). Poultry litter sources resulted in the lowest cost per ton for both years of the trial.

“…There are many studies investigating the variability within and between species for traits related to efficiency in the use of phosphorus and its genetic control (Whiteaker et al, 1976;Brasil et al, 2007;Boutraa, 2009;Zhang et al, 2009;Missaoui and Young, 2016). These genotypic variations clarify the adaptation of genotypes to several conditions of environmental stress and make up the genetic basis for the implementation of breeding programs.…”
