Seasonal and annual dry matter production of ryegrass was compared with drought- and grass grub-tolerant species Grasslands Roa tall fescue (Festuca arundinacea Schreb.), Grasslands Maru phalaris (Phalaris aquatica L.) and Grasslands Kara cocksfoot (Dactylis glomerata L.) as both single species and different combinations of mixes in two trials from 1982 to 1991. In trial 1, Nui ryegrass (damaged by Argentine stem weevil) produced significantly less than cocksfoot, phalaris and mixtures of the drought-tolerant grasses. Yatsyn-1 ryegrass in trial 2 was not subjected to stem weevil attack and the annual dry matter production was significantly higher than that of tall fescue and, although not significantly, higher than that of phalaris and cocksfoot. In both trials the highest producing mixture was the phalaris/ cocksfoot mix with the exception of the triple mix of phalaris/cocksfoot/tall fescue in trial 2. The phalaris/cocksfoot mix produced significantly more than phalaris as a single species and although not significant, 14% more than cocksfoot suggesting these species are complementary in a mix. The triple mix in trial 2 produced significantly more than all single species except ryegrass. Mixes of srgnificant. tall fescue/phalaris and tall fescue/cocksfoot had no advantage in DM production over single-species sowings of phalaris or cocksfoot, but improved yields over tall fescue. These results show possible complementary effects to sowing phalaris and cocksfoot. The addition of tall fescue to the mix had small and non-significant benefits.

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.

Dry matter (DM) production and seasonal distribution of old ryegrass/white clover pasture defoliated at 14- and 28day intervals, and new sowings of 'Grasslands Maru' phalaris (Phaluris aquatica L.), 'Grasslands Roa' tall fescue (Festuca arundinacea Schreb.), and 'Grasslands Kara' cocksfoot (Dactylis glomerata L.) at 28day defoliation intervals were evaluated in an environment prone to grass grub damage and dry summer/autumn periods. Under a 28&y defoliation interval old ryegrass produced 2O%more DM that the 14-day defoliation interval, the difference occuring mainly in spring. Annual production, in the initial 4 years, of phalaris and tall fescue was respectively 17 % and 20 % more than that of old ryegrass. Phalaris was superior to old ryegrass in all seasons. Cocksfoot annual production was similar to that of old ryegrass, producing more in summer (9%) and autumn (19%) but 15% less in spring. Results from year 5 and 6 suggest that phalaris may not be as persistent as tall fescue. A 28-day rotation in spring is recommended to maximise production of old ryegrasslclover pasture. Phalaris and tall fescue are recommended as alternative species to old ryegrass in a grass grub prone and/or summer dry environment. Cocksfoot is not recommended.

Dactylis Glomerata L

Over the last 10 years Canterbury farmers have started to diversify their pasture base in order to optimise their stock production. While ryegrass is still the base grass of our pastoral system, it is unsuited to many sites where pasture must generate high stock growth rates despite seasonally low rainfall, high soil temperatures and pasture pest challenge. On such sites, pastures based on cocksfoot, (Dactylis glomerata L.), phalaris (Phalaris aquatica L . ) and tall fescue (Festuca arundinacea Schreb.) or prairie grass (Bromus willdenowii Kunth, cv. 'Grasslands Matua') or lucerne (Medicago sativa) or chicory (Cichorium intybus L.) have lifted net farming returns.

Dactylis Glomerata L

A study of nine clones of cocksfoot (Dactylis glomemta) showed that differences between clones in dry matter production were not associated with tillering ability. The clones, seven of Mediterranean origin and two from Great Britain, were grown under the spacing conditions of a breeding nursery and in swards, but were not defoliated. Individual plant weight and tiller number were greatly reduced by sward conditions, as compared with plants under spaced conditions. Tiller weight was much less affected. Thus the lower individual plant weight in swards was associated mainly with fewer tillers. Tiller numbers in the swards rose to a peak during the second year, followed by a decline to the end of the growing season. The decline, which differed between clones, was related to plant weight and was probably correlated with the mutual shading of the plants.

This study measured total dry matter production and botanical composition of binary mixtures of cocksfoot (Dactylis glomerata), ryegrass (Lolium perenne) or tall fescue (Festuca arundinacea), as a replacement series in proportions of 100:0, 75:25, 50:50, 25:75 and 0:100 from June 1987 until May 1993. The binary mixtures were sown in March 1986 with white clover, on an occasionally drought affected Kaweku silt loam, with an average annual rainfall of 750 mm near Riversdale, in Southland. Mixtures with ryegrass were allowed a 6-month establishment period before ryegrass was overdrilled in early October 1986. Total yields of ryegrass/cocksfoot mixtures increased as ryegrass seeding rate increased. Clover yields were generally unaffected. Mixtures of cocksfoot/tall fescue produced more sown grass than either species sown alone. This lowered clover and other grass yields, resulting in no total dry matter yield improvement in mixtures compared to pure sowings. Tall fescue/ ryegrass mixtures were competitive in winter and spring with lower total yields than either species sown alone. This competition also lowered other grass yields. During summer and autumn the total production increased as the amount of ryegrass increased. Seed mixtures with two perennial temperate pasture grasses did not provide any extra pasture production in a cool temperate environment under infrequent hard grazing management. The best choice for the region would be the grass that provided the greatest dry matter yield. Other components such as clover may be reduced when mixing grasses.

1. Net pasture dry matter production and available pasture dry matter were measured over 3 years in a small-scale replica of the study of the effects of dairy cow grazing management and stocking rate reported by McMeekan & Walshe (1963).2. The four treatments were(i) Controlled rotational grazing, light stocking rate (0.95 cows/acre).(ii) Controlled rotational grazing, heavy stocking rate (1.19 cows/acre).(iii) Uncontrolled, set stocked grazing, light stocking rate (0.95 cows/acre).(iv) Uncontrolled, set stocked grazing, heavy stocking rate (1.19 cows/acre).3. The pasture measurement technique employed measured net pasture production (gains through new growth minus losses from all sources). It is argued that this parameter, rather than absolute pasture production, governs the changes in the dry matter feed supply to the grazing animal.

Birdsfoot trefoil (Lotus corniculatus L. ’Viking’) was seeded directly into a predominantly orchardgrass (Dactylis glomerata L.) sward following overall or banded applications of paraquat (1,1′-dimethyl-4, 4′-bipyridinium ion, as dichloride salt) or glyphosate [N-(phosphonomethyl)glycine, as isopropylamine salt] to determine the degree of sward control necessary for stand establishment without tillage. Effects of the herbicide treatments and the seeding on botanical composition and dry matter production were determined by a vertical intercept technique and by hand separations of harvests into botanical components. Trefoil establishment was proportional to the degree of sward control during the seeding year. Little trefoil was established by direct seeding without herbicides. The banded herbicide treatments were less effective than overall herbicide applications for trefoil establishment. Trefoil yield obtained following overall application of paraquat was approximately 65% of that obtained following overall glyphosate treatment.Key words: Dactylis glomerata, glyphosate, Lotus corniculatus, herbicide, no-tillage, paraquat

Intensively Managed

Pasture is the cheapest source of feed for dairy cows, therefore, dairy pastures in Australia are intensively managed to maximise milk production and profits. Although soil testing commonly suggests that soils used for dairy pasture production have adequate supplies of phosphorus (P), many Australian dairy farmers still apply fertiliser P, often by applying smaller rates more frequently throughout the year. This study was designed to test the hypotheses that more frequent, but lower rates of P fertiliser applied strategically throughout the growing season have no effect on dry matter production and P concentration in perennial ryegrass (Lolium perenne L.), when soil extractable P concentrations are above the critical value reported in the literature. Three field sites were established on rain-fed dairy pasture soils ranging in P sorption capacity and with adequate soil P concentrations for maximising pasture production. Results showed that applied P fertiliser had no effect on pasture production across the 3 sites (P > 0.05), regardless of rate or the season in which the P was applied, confirming that no P fertiliser is required when soil extractable P concentrations are adequate. This finding challenges the viability of the current industry practice. In addition, applying P fertiliser as a single annual application in summer did not compromise pasture production at any of the 3 sites (P > 0.05), which supports the current environmental recommendations of applying P during drier conditions, when the risk of surface P runoff is generally lower. The current results also demonstrate that the short-term cessation of P fertiliser application may be a viable management option, as a minimal reduction in pasture production was measured over the experimental period.
