“…Decreasing CP concentration has been associated with less frequent harvests. Vendramini et al (2008) described decreasing CP concentration in Tifton 85 when the regrowth interval increased from 2 to 4 wk. Similar results were reported by Liu et al (2011a), who evaluated effects of three harvest frequencies (14, 21, and 28 d) and postgraze stubble heights (8, 16, and 24 cm) on Tifton 85.…”

Seasonal Herbage Accumulation and Nutritive Value of Irrigated ‘Tifton 85’, Jiggs, and Vaquero Bermudagrasses in Response to Harvest Frequency

Grasses within the Cynodon genus are widely used perennial forages, and ‘Tifton 85’ (Cynodon spp.) is one of the most popular commercial cultivars. Jiggs and Vaquero are new C. dactylon (L.) Pers. grasses, but there is little information comparing their performance with Tifton 85 under tropical conditions. The objectives were to describe and explain variation in seasonal herbage accumulation (HA) and nutritive value of irrigated Tifton 85, Jiggs, and Vaquero bermudagrasses in response to harvest frequency (14, 28, and 42 d). The trial was performed for 2 yr in Piracicaba, Brazil, on a Kandiudalfic Eutrudox soil. In the warm season, total HA of Jiggs was similar to Tifton 85, and both were more productive than Vaquero. Under the 42‐d frequency, Jiggs had greater annual HA than the other grasses (28.5 vs. 23.7 and 20.1 Mg ha−1, for Tifton 85 and Vaquero, respectively), but when harvested every 28 d, Tifton 85 and Jiggs HA were similar (18.5 Mg ha−1). For the 42‐d harvest interval in the cool season, Jiggs had the greatest HA (10.2 Mg ha−1). Less frequent harvests in both seasons resulted in greater HA. Tifton 85 had a greater proportion of leaves than Jiggs and greater in vitro digestible organic matter (IVDOM) than the other grasses in the warm season. Considering these responses, harvest frequency of Jiggs and Tifton 85 should be ∼28 d in the warm season, while that of Vaquero should be ∼42 d. No single harvest management will be appropriate for all Cynodon grasses.

“…Corriher et al (2007) reported that average daily gain (ADG) was greater for suckling calves grazing Tifton 85 vs. Coastal pastures (0.94 vs. 0.79 kg d −1 ). Despite the improved quality of Tifton 85 relative to other bermudagrasses, longer regrowth periods decrease Tifton 85 nutritive value and consequently may affect animal performance (Vendramini et al, 2008; Mandebvu et al, 1999).…”

ForagesA gronomy J our n al • Volume 10 0 , I s sue 6 • 2 0 0 8 ABSTRACT Th ere has been limited research to defi ne appropriate management practices for pastures grazed by early weaned calves. Experiments were conducted from January to April (cool season) and May to July (warm season) 2003 and 2004 to evaluate the eff ects of N fertilization and regrowth interval on herbage mass and nutritive value of rye (Secale cereale L.)-annual ryegrass (Lolium multifl orum Lam.) mixtures and 'Tift on 85' bermudagrass (Cynodon sp.). Treatments were the factorial combinations of three N fertilization rates (0, 40, and 80 kg ha −1 period −1 , with two periods per season) and two regrowth intervals (3 and 6 wk for rye-ryegrass and 2 and 4 wk for bermudagrass). Rye-ryegrass herbage mass increased linearly from 0.9 to 1.8 Mg ha −1 period −1 as N fertilization increased. Th ere was no eff ect of regrowth interval on rye-ryegrass herbage mass during the winter; but in the spring, herbage mass was greater for the 6-wk vs. the 3-wk interval (2.2 vs. 1.6 Mg ha −1 ). For bermudagrass, there was a linear increase in herbage mass (1.6 to 2.6 Mg ha −1 period −1 ) and in vitro digestible organic matter (IVDOM) (480 to 530 g kg −1 ) with increasing N fertilization. Regrowth interval eff ects on rye-ryegrass were more important in spring than winter in determining forage nutritive value and herbage mass; shorter regrowth intervals may be necessary in spring to maintain calf gains. During the warm season, shorter regrowth intervals for Tift on 85 resulted in forage with greater nutritive value, which is the key factor limiting growth of early weaned calves.

“…Live herbage N concentration increased linearly (P < 0.0001) from 7.9 to 13.5 g kg −1 with increasing N fertilizer level (Table 2). Vendramini et al (2008a) reported that crude protein concentration in Tifton 85 herbage increased linearly (from 140 to 190 g kg −1 and 115 to 135 g kg −1 for 2-and 4-wk regrowth intervals, respectively) with increasing N fertilization from 0 to 80 kg ha −1 . Increasing N fertilization resulted in increased N uptake by the plant and greater plant-tissue N concentration (Haynes and Williams, 1993).…”

Nitrogen (N) fertilization affects grassland herbage accumulation and nutritive value, but its effect on the distribution of nutrients among soil and plant nutrient pools is less understood. This 2‐yr study determined the effect of N fertilization levels of rotationally stocked ‘Tifton 85’ bermudagrass (Cynodon spp.) pastures on nutrient concentration and content in soil (top 20 cm), live root‐rhizome mass, live herbage mass, and aboveground plant litter pools. Treatments were 50, 150, and 250 kg N ha−1 yr−1. Greater N fertilization increased N concentration in all plant nutrient pools and potassium (K) concentration in live herbage and plant litter, but plant‐pool phosphorus (P) concentrations changed little across N levels. With increasing N fertilization, live herbage (118–159 kg ha−1) and plant litter (8–14 kg ha−1) K pools increased linearly, but the Mehlich‐1 extractable soil K pool decreased linearly (182–139 kg ha−1); live herbage (50–92 kg ha−1), plant litter (30–49 kg ha−1), and root rhizome (63–95 kg ha−1) N pools also increased with increasing N fertilization. The proportion of K in various pools was affected more by N fertilization than were proportions of N, P, or carbon. Soil was the dominant pool for all nutrients, with the exception of K in pastures fertilized at the greatest N level. Increasing N fertilization increased the proportion of K and N contained in plant pools and decreased the proportion in soil. Although N fertilization affected quantity and proportion of nutrients in pools in Tifton 85 pastures, changes occurred to a limited extent, with the exception of plant and soil K pools.
