Herbage dry matter (DM) production, botanical composition and nutritive value were compared over 2 years under irrigation and dairy cow grazing for simple two-species grass (perennial ryegrass or tall fescue)- white clover pastures and diverse pastures where herbs (chicory and plantain), legumes (red clover and lucerne) and prairie grass were added to the simple mixtures. Averaged over 2 years, annual herbage DM production was 1.62 t DM/ha greater in diverse (16.77 t DM/ ha) than simple (15.15 t DM/ha) pastures, primarily reflecting greater DM production in summer. Diverse pastures had lower metabolisable energy (ME) (12.0 vs 12.2 MJ ME/kg DM) and neutral detergent fibre (301 vs 368 g/kg DM) content than simple pastures, although the total ME produced per year was greater in diverse than simple pastures (202 vs 185 GJ ME/ha). Ryegrassbased pastures had higher annual DM production than tall fescue-based pastures in the first but not second year. The results indicate that including additional legumes and herbs with simple grass-white clover pastures may increase total DM and ME production of dairy pastures under irrigation.

Herbage dry matter (DM) production, botanical composition and nutritive value of pastures were measured in response to the application of 24 g/ ha gibberellic acid (GA; 60 g ProGibb®/ha) and 50 kg N/ha nitrogen fertiliser (N; 106 kg urea/ha) in autumn. Responses were compared for simple two species grass (perennial ryegrass or tall fescue)-white clover pastures and multi-species pastures where herbs (chicory and plantain), legumes (red clover and lucerne) and prairie grass were sown with the simple mixtures. Four weeks after application, the increase in DM yield averaged across pasture mixtures relative to untreated plots was 273, 104, and 493 kg DM/ha for GA alone, N fertiliser alone, and GA and N combined, respectively. Application of GA increased the white clover percentage in all pastures except simple tall fescue pastures. The percentage of herbs in multispecies pastures was increased by application of N but not GA. Crude protein concentration was decreased by GA application in all pastures except simple ryegrass pastures. The results from this study show that it is important to consider the botanical composition of pastures when determining the effect of GA on DM yield and nutritive value.

The effect of replacing white clover with fertiliser nitrogen (N) on dry matter production and grass grub populations in 'Grasslands Roa' tell fescue (Festuca arundinacea Schreb.), 'Grasslands Mat-u' phalaris (Phalutis aquatica L.), 'Grasslands Kara' cocksfoot (Dactylis glomerata L.), 'Grasslands Mama' prairie grass (Bromus willdenowii Kunth) and 'old' (30 year plus) ryegrass was measured over a 2 year period. For all pastures the replacement of white clover with fertiliser N significantly reduced grass grub numbers. This was greatest in tall fescue, phalaris and cocksfoot, showing that pure swards of these species were resistant to grass grub. Decreases in grass grub numbers in ryegrass and prairie grass were less. There was overall a significant increase in pasture production by eliminating white clover and applying fertiliser N, with a differential response between species. Average annual production of prairie grass was unaffected, whereas the yield of cocksfoot increased by 9 % and old ryegrass, phalaris and tall fescue increased by 26 % . Most of this extra production for tall fescue and phalaris occurred in autumn. These results show that the use of tall fescue and phalaris and the replacement of white clover with fertiliser N has potential for increasing pasture production in districts subject to grass damage.

Clover Pasture

Many farmers are sowing mixed swards containing chicory (Cichorium intybus), plantain (Plantago lanceolata), red clover (Trifolium pratense) and white clover (T. repens) (hereafter termed herb and clover mix). This herb and clover mix has comparable annual dry matter (DM) production to perennial ryegrass white clover pasture (rye/wc), however, it has a different pattern of growth, producing more DM during summer and autumn. The herb and clover mix also has a higher nutritive value and is able to support greater rates of animal production, especially over summer, than rye/ wc in both sheep and cattle. The herb and clover mix is most suited to a rotational grazing interval of 3-4 weeks to an 8 cm residual height, with no winter grazing. When managed appropriately the herb and clover mix is able to persist for at least 2 years and up to 5 years under both sheep and cattle grazing.

Capacitance Probe

The production of herbage by five pasture species—Phalaris tuberosa (phalaris), Festuca arundinacea (tall fescue), Lolium perenne (perennial ryegrass), Trifolium repens (white clover) and Medicago sativa (lucerne)—was measured when they were grown in the field in monoculture, and by phalaris and white clover when grown in mixture. The plots were irrigated to prevent water deficits, and five levels of nitrogen were included; the mixture was also grown under dryland conditions. All plots were defoliated at intervals during a period of 3 years. A capacitance probe was used in an attempt to determine harvest times more objectively, and to establish long-term relationships between meter readings and components of plant yield. Major differences in production were detected between the species, lucerne producing most in the first 2 years of the experiment. Nitrogen and available soil moisture affected both production and botanical composition, and significant differences were detected in species' responses to applied nitrogen and in nitrogen recovery. The performance of lucerne and tall fescue suggests that both species deserve to be more widely grown on the Northern Tablelands of New South Wales.

Clover Content

The effects of superphosphate (0, 42, 125, and 375 kg ha-1 year-1), grass species (tall fescue, perennial ryegrass, and phalaris) and grass seeding rate (0, 1.1, 4.5, and 17.9 kg ha-1) on the productivity and botanical composition of grass-white clover pastures were investigated from 1967 to 1970 on a previously unfertilized site at Armidale, New South Wales. In all years, total pasture yields were increased by each additional increment of superphosphate applied. During the establishment year, the addition of 375 kg ha-1 superphosphate increased clover dry matter yield by more than 3500 kg ha-1, whereas grass production was low (< 1500 kg ha-1) on all treatments. Thereafter, the increases in grass yields at each level of superphosphate were the equal of, or exceeded, the clover responses, which were mainly linear throughout the experiment. Neither grass seeding rate nor grass species had a major effect on total pasture productivity. Their effects on the relative yields of the grass and clover components were most evident at the highest rate of superphosphate. At SP0, grass and clover percentages declined from 1967 to 1970 and at SP125 the proportions of grass, clover and weeds were about equal in all years. At SP375, the strong overall trend from clover-dominance in 1967 to grass-dominance in 1970 was most rapid in treatments sown with 4.5 or 17.9 kg ha-1 grass and least rapid in phalaris-white clover pastures. In 1969 and 1970, when most pastures at SP375, had reached the grass-dominant stage of their development, within-year fluctuations in grass and clover content were least in the fescue-white clover pastures.

Abstract Renovating toxic-infected tall fescue (Lolium arundinaceum) (TF) pastures to novel endophyte tall fescue (NE) is a solution to mitigate the negative associated effects of toxic fescue in beef cattle. However, beef cattle producers are uncertain of the payback period for costs associated with renovation techniques in terms of farm profitability and agronomic performance. In 2018, three renovation strategies were implemented in a randomized complete block design in Bahama, NC. Strategies included: 1) control (C), 2) renovation to NE after one season of a single specie cover crop (1-SM), 3) renovation to NE after three seasons of a single specie cover crop (3-SM), and 4) renovation to NE after three seasons of a multi-specie cover crop (3-CM). Each treatment plot (0.81 ha) was evaluated for botanical composition and hay was harvested in May and August of 2020. Round bales from each treatment were weighed to determine yield and core sampled to determine nutritive value. Data were analyzed using proc GLIMMIX of SAS v9.4. Combined forage yield was greater (P = 0.0226) for 3-CM (8,816 kg/ha) compared to 3-SM (7,191 kg/ha) and C (6,920 kg/ha), but did not differ from 1-SM (7,775 kg/ha). Crude protein concentration was greater (P = 0.035) for C (10.2%) in comparison to 3-SM (9.35%) in harvest 1, but was not different (P = 0.93) in harvest 2. Percentage of fescue in the sward was greatest (P = 0.0002) for 3-SM and least for C (84.9 and 62%, respectively). Similarly, presence of undesirable plants was greater (P &lt; 0.0001) for C (37.5%) than 1-SM, 3-CM and 3-SM (23.7, 15.2 and 12.7%, respectively). Percentage of bare ground did not differ among treatments (P = 0.31). Data suggest agronomic performance for 3-CM and 3-SM was improved compared to C in years following pasture renovation.

Five grasses (Nui ryegrass, Roa tall fescue, Matua prairie grass, Maru phalaris and experimental cocksfoot selection K1858) were sown in mixtures with Pawera tetraploid red clover and compared with a pure sward of Pawera and with a Ruanui ryegrass/Huia white clover control. Yields were taken when mean herbage height was 18 cm by cutting quadrats to 4 cm. Sufficient sheep were used to graze herbage in 48 hours on a 'Cafeteria' basis. Matua, the most rapidly establishing grass, yielded 900 kg DM/ha of sown grass at the first grazing, 4 to 6 times more than cocksfoot. Roa and Ruanui, and 30% more than Nui and Maru. During the next two years, the Matua/Pawera mixture outyielded other mixtures, with most of its superiority evident in the summer and winter. All mixtures outyielded Ruanui/Huia over the same period.The grasses evaluated varied in their compatability with Pawera, the more aggressive the grass the greater the suppression of DM yield of Pawera in the mixture. However, even the most aggressive grass mixture yielded more legume at each grazing than did the Ruanui/Huia pasture. The place of Matua, Nui and Pawera as useful varieties in this summer dry environment are discussed.

Yellow bristle grass (Setaria pumila) and summer grass (Digitaria sanguinalis) are summer-active annual grass weeds which infest temperate dairy pastures. A study was undertaken over 2 years to compare hand-sown yellow bristle and summer grass establishment, survival, and seed production in pastures grazed by dairy cows and based on (i) tetraploid perennial ryegrass (Lolium perenne), (ii) tetraploid perennial ryegrass and white clover (Trifolium repens), and (iii) tall fescue (Festuca arundinacea) and white clover, to determine which pasture type offered the greatest resistance to these grass weeds. Ingress of grass weeds was similar in all three pasture types. Total dry matter production was similar for all pasture types for the first year and lower in tall fescue + clover than perennial ryegrass pasture in the second year. All pasture types had a similar distribution of microsite types (bare ground ± canopy, basal cover ± canopy) in both years. The annual grass weeds were most prevalent in bare ground + canopy microsites, which were also the most frequent of the four microsite types. In the first year, <5% of microsites were occupied within 2 months of sowing, whereas in the second year, microsite occupation remained >13% for all assessments. In the first year, panicle production of yellow bristle and summer grass was similar (averaging 4.1 panicles plant–1); in the second year, panicle production was greater for summer grass (0.80 v. 0.16 panicles plant–1, respectively). Where present, these annual grass weeds are likely to spread in dryland dairy pastures sown with either perennial ryegrass or tall fescue. Variability in their panicle production between years shows how their impact on pasture performance and consequent need for control measures will also vary from year to year.

Establishment, botanical composition and production of direct-drilled perennial ryegrass and tall fescue were compared for two seeding rates in an autumn-sown, grazed trial. Tall fescue (Festuca arundinacea Schreb. cv. AU Triumph) was sown at either 17 or 3 1 kg/ha and perennial ryegrass (Lolium perenne L. cv. Grasslands Supernui) was sown at 12 and 23 kg/ha on 12 April, 1990 all with "Grasslands Pitau" white clover at 3 kg/ha. Measurements of herbage mass and botanical composition during the ensuing 2-year period showed that there was no advantage in terms of suppression of weed species or accumulation of herbage mass of the sown species from sowing more seed than that required to achieve a population of 450-500 plants/m2 of either ryegrass and tall fescue 6 weeks after sowing. A population of 150 white clover plants/m2 appeared to be adequate for development of a balanced sward. Establishment of fescue was slower than that of ryegrass but both species developed to productive swards after infrequent but close defoliation with dairy cattle in the first spring and subsequent rotational grazing by lactating dairy cows. Pasture establishment in Northland is difficult because of shallow topsoils. Direct drilling can preserve this fragile topsoil and successfully establish alternative species such as fescue as long as attention is paid to their establishment requirements. Alternative species may offer a solution to low feed availability of ryegmss in the summer and poor survival of ryegrass in poorly drained areas during the winter.

Milk production by Jersey cows grazing a common allowance of irrigated or non-irrigated pastures over four summers (1997-2000) is described. The pastures were: (1) high-endophyte perennial ryegrass-white clover (2) tall fescue, phalaris, cocksfoot, white clover, red clover (3) same as (2) plus paspalum (4) endophyte-free ryegrass, timothy, white clover, red clover and (5) existing high-endophyte ryegrass-white clover. Irrigation improved milksolids yield by 5% over 4 years, with inconsistent effects on milk composition, no effects on pasture in vitro digestibility and nitrogen content, and usually no effect on pasture botanical composition. In 1997, cows on (1) produced the lowest milksolid (MS) yields. Cows grazing ryegrass-white clover (1 and 5) produced less than those on tall fescue-based pastures (2 and 3) (0.74 vs 0.86 kg MS/cow/day) in 1998, and the yields of cows on ryegrass/timothy-based pastures (4) were best (0.96 kg MS/cow/day). The same trends in milksolids yield occurred in 1999, except for cows on (1) which were similar to (4). Cows on existing pasture often produced the lowest milksolid yields. Trends in milksolids production over the 4 years reflected trends in total clover (red + white) contents.
