“…Preinoculated Apache arrowleaf clover (Smith et al, 2004) was planted at 17 kg ha −1 . Annual ryegrass was planted at 34 kg ha −1 and included ‘TAM 90’ (Nelson et al, 1992) in 2002 to 2007, ‘TAMTBO’ (Nelson et al, 2007) in 2008 to 2009, and ‘Nelson’ (Nelson et al, 2011) in 2010 to 2013. A blend of 0–8–15–8–4.25–0.2 of N–P–K–S–Mg–Bo was applied at 437 kg ha −1 as a single application in the fall (November–December) to both arrowleaf clover and ryegrass pastures.…”

Bermudagrass [Cynodon dactylon (L.) Pers.] pastures are often overseeded with annual ryegrass (Lolium multiflorum Lam.) and/or clovers to extend grazing. The bermudagrass pastures were stocked at three levels of forage mass to quantify cow and calf average daily gain (ADG, gain ha−1) and its relationship with mass and allowance (forage dry matter/animal body weight [DM:BW]). From 2002 through 2013, ‘Coastal’ and common bermudagrass pastures were overseeded with either ‘Apache’ arrowleaf clover (Trifolium vesiculosum Savi.) without N fertilization or annual ryegrass plus N. Calf ADG was greater (P < 0.001) on arrowleaf clover and ryegrass from February to mid‐June (spring) compared with Coastal and common bermudagrass from mid‐June to late September (summer). Calf ADG was similar for bermudagrass pastures in spring, but different (P < 0.001) at all three stocking levels for low (1.42 kg d−1), medium (1.22 kg d−1), or high (0.90 kg d−1) stocking rates. Cow ADG in spring was greater (P < 0.01) for ryegrass (0.41 kg d−1) than for arrowleaf clover (0.22 kg d−1), and at all three stocking levels. In summer, calf ADG was affected by stocking (P < 0.001) at low (1.05 kg d−1), medium (0.81 kg d−1), and high (0.58 kg d−1) stocking rates. Cow ADG in summer varied by stocking level (P < 0.01), bermudagrass pasture (P < 0.04), and stocking level × bermudagrass pasture interaction (P < 0.04). Calf ADG was optimum at 2000 to 2500 kg ha−1 mass in spring, and 3000 to 3500 kg ha−1 mass in summer. Optimum allowance for calves was 1.2 to 1.5 (DM:BW ) in spring and 1.5 to 2.0 in summer. A two‐phase linear relationship best fit mass and allowance with cow and calf ADG for the overall 11 yr.

“…Jumbo (Prine et al, 2002) is a tetraploid cultivar released by the University of Florida. Both of the above TAES lines were derived from germplasm of `TAM 90' (Nelson et al, 1992), which had been treated with colchicine to double the chromosome number from 14 to 28. TXR2000-T2 had been selected (high forage potential) in a space planted nursery at Overton in 1997-1998.…”

“…In the seedling stage, Axcella 2 has rolled leaves and no auricles. Mature plant height of Axcella 2 was 21 cm shorter (P < 0.01) than 'Axcella' (Nelson et al, 2001) and 14 cm shorter than Panterra and is much shorter than forage-type cultivars such as 'TAM 90' (Nelson et al, 1992) and 'Gulf' (Weihing, 1963). Spike length of Axcella 2 was 3.5 cm shorter (P < 0.01) than Panterra and 5 cm shorter than Axcella.…”
