This paper reports the results of an initial evaluation of a large collection of Australian perennial native grasses. The overall aim of the research was to identify accessions that may be useful for pastoral purposes and for controlling land degradation on hill-lands in the high (>500 mm) rainfall zone of south-eastern Australia. Accessions (807) representing 37 target species were established in spaced plant nurseries at Rutherglen and Wagga Wagga. Dactylis glomerata L. cv. Porto and Eragrostis curvula (Schrad) Nees. Complex cv. Consol were established as comparator (control) species. A range of attributes was observed over a 2-year period (19900—1992), including persistence, vigour, productivity, palatability, morphology, and characteristics related to seed production. Accessions were initially culled on the basis of their persistence. Data for a range of attributes were separately analysed using pattern analysis to provide a broad overview of the performance and characteristics of the remaining accessions. A number of selection criteria were applied which resulted in selection of a promising group of 20 accessions (12 species from 8 genera). The promising group of accessions will be evaluated further at field sites typical of hilly landscapes in the 500mp;mdash;600 mm rainfall zone of south-eastern Australia.

Take All

The incidence of take-all of wheat, caused by Gaeumannomyces graminis var. tritici (Ggt), and eyespot, caused by Tapesia yallundae, was examined in a long-term rotation-tillage experiment at Wagga Wagga, N.S.W. Take-all occurred in years of higher August-October rainfall from 1979 to 1984. In years with take-all, soil water in the upper 20 cm was estimated to be above permanent wilting point for the growing season. Eyespot was associated with above-average rainfall during winter and spring and was more prevalent where residues of wheat or grasses were retained. After the severe drought of 1982, take-all developed to high levels in 1983 in wheat that followed wheat, lupins or pasture when stubble was retained, but was reduced in 1984 after lupins. Take-all was reduced in the lupin-wheat rotations by removing stubble through burning or by early incorporation of stubble. Take-all incidence was less in wheat that followed grazed pasture than after mown pasture. Where stubble was retained, Ggt survived on stubble from wheat in 1981, through the drought of 1982, to infect wheat in 1983, but inoculum did not survive on stubble through the wet season of 1983 to infect wheat in 1984. Regression analysis indicated that take-all was negatively correlated with yield but eyespot was not. Take-all reduced yield by reducing kernel mass in 1 year and by reducing kernels per cm2 in 2 other years. Soil water conditions that were associated with take-all development from 1979 to 1984 occurred in 50% of years from 1960 to 1989.

Nitrogen balances of narrow leaf lupin (Lupinus angustifolius L.), albus lupin (L. albus L.), field pea (Pisum sativum L.), chickpea (Cicer arietinum L.), and barley (Hordeum vulgare L.) sown over a range of dates were examined in 1992 in a rotation study at Wagga Wagga, NSW. Each N budget included assessment of dependence on fixed as opposed to soil N, peak aboveground biomass N, and N removed as grain or returned as unharvested aboveground crop residues. N balances of wheat sown across the plots in 1993 were assessed similarly in terms of biomass and grain yield. Yields, N2 fixation, and crop residue N balances of the legumes were markedly influenced by sowing time, and superior performance of lupins over other species was related to higher biomass production and proportional dependence on N2 fixation, together with a poorer harvest index. Residual N balances in aboveground biomass after harvest of the 1992 crops were significantly correlated with soil mineral N at 1993 sowing and with biomass and grain N yields of the resulting wheat crop. Best mean fixation and grain N yield came from albus lupin. Wheat grain N yields following the 2 lupins were some 20% greater than after fiield pea and chickpea and 3 times greater than after barley. Net soil N balance based solely on aboveground returns of N of legumes in 1992 through to harvest of wheat in 1993 was least for narrow leaf lupin-wheat ( –20 kg N/ha), followed by albus lupin-wheat ( –44), chickpea-wheat ( –74), and field pea-wheat ( –96). Corresponding combined grain N yields (legume+wheat) from the 4 rotations were 269, 361, 178, and 229 kg N/ha, respectively. The barley-wheat rotation yielded a similarly computed soil N deficit of 67 kg/ha. Data are discussed in relation to other studies on legume-based rotations.

Lamb Growth

Lamb growth, carcass and pelt measurements are reported from 5775 lambs born to Border Leicester × Merino (BLM) and Hyfer (Dorset × Merino composite) ewes joined to Dorset, Suffolk and Hyfer rams in three lamb-production systems at Cowra and Wagga Wagga over 5 years. The production systems involved lambings at different seasons of the year and increasing levels of intensification from autumn annual joining, spring joining with a backup mating for non-pregnant ewes, to an accelerated 8-monthly lambing system. Lambs from BLM ewes were 0.7 kg heavier at birth and grew 3% faster and reached slaughter, at 18 kg carcass weight, 1–2 weeks earlier than did lambs from Hyfer ewes (P < 0.01). The advantage in growth rate of lambs from BLM compared with Hyfer ewes was greater for lambs born in November. These lambs had poorer growing conditions over the summer months, with 22% lower growth rate and taking 5 weeks longer to reach slaughter than did lambs born in March or August. There was no difference between Dorset and Suffolk sire breeds for any lamb growth traits, with lambs from Hyfer sires growing 7% slower. Ram and cryptorchid lambs reached slaughter 1 week earlier than did wethers, with ewes a further 9 days later (P < 0.01). Sex differences were maximised when lamb growth was greatest. There were no differences in carcass fat measurements between ram and cryptorchid lambs, although both were considerably leaner than wethers (2.2–3.0 mm fat at the GR site), which were 1.3–2.1 mm leaner than ewes at 18-kg carcass weight. The range in average growth rate of progeny of the BLM ewes from the 12 different source flocks at Cowra and Wagga Wagga was 10–14% of the mean which was twice the difference in average growth rate of progeny from the BLM and Hyfer dams. There was also significant variation among the BLM source flocks for carcass fat measurements. Lamb progeny from the different sire- and dam-breed combinations had varying levels of heterozygosity. There appears to be little loss of heterosis or hybrid vigour for lamb growth, although the sire breed × dam breed interaction was significant (P < 0.01) for age at slaughter at Wagga Wagga, in which the ranking of the lamb types was consistent with the levels of heterozygosity. The estimates of between-lambing repeatability for the ewes were highest for birthweight (0.35 Cowra and 0.27 Wagga Wagga) and declined at later ages (0.26–0.17), with lower estimates for carcass traits.

The response of wheat to the length of fallow, to the number of cultivations, and to pre-planting chemical control of weeds on high fertility soils was determined under winter rainfall conditions at Wagga Wagga, New South Wales, over four years commencing 1960-61. Length of fallow had little influence on the conservation of rainfall except in 1961-62, when approximately twice the average summer rainfall added 1.8 inches of soil moisture per acre 48 inches. Long fallow increased available nitrogen accumulation, but this did not increase yield over either the mechanically prepared shorter fallows, or pre-planting chemical weed control. This was due to losses during the autumn-winter period of some of the excess mineral nitrogen that accrued during the long fallow. High mineral nitrogen concentrations also occurred during the summer on weed-free, uncultivated soils. Grain yield after a single autumn cultivation was as high as after a long fallow except in 1961-62. In this year the long fallow (September to May) significantly increased yields over all other treatments. The absence of any positive yield response to the application of 60 to 80 lb nitrogen an acre to short fallows suggests that mineral nitrogen concentrations were generally adequate for grain production. The addition of nitrogen to long fallows often depressed yields. The dependence of grain yield on adequate weed control is illustrated by a highly significant negative correlation (r = -0.849 ; P<0.001) of grain yield with weed growth. It is concluded that in the Wagga Wagga environment weed control is more important than moisture conservation and mineral nitrogen accumulation through fallowing.

In a red-brown earth soil from Wagga Wagga the fluctuations in the level of mineral nitrogen (ammonia plus nitrate-nitrogen) and its availability to wheat under growing period rainfalls of 6 inches and 16 inches were studied. Ammonia-nitrogen did not exceed 8 lb nitrogen per acre 6 inches but showed statistically significant short term fluctuations. Mineral nitrogen decreased steadily from the 4-5 leaf stage of plant growth, reaching minimum values in the ear-emergence period when a temporary nitrogen deficiency occurred. Following rainfalls of about one inch or more, conditions favoured biological activity and nitrogen was mineralized, absorbed by the crop and/or leached down the profile. In one season a release of mineral nitrogen about two weeks before flowering contributed an estimated 20-30 per cent of the total nitrogen uptake of the crop. Nitrogen uptake by the wheat crop ceased after flowering and subsequent changes in mineral nitrogen level reflect the net result of mineralization and demineralization processes, and nitrogen uptake by weeds, particularly skeleton weed. Absorption of nitrogen from the profile depended upon seasonal conditions, with the surface 18 inches suppling the greater part of the nitrogen absorbed by the crop. This indicates the need to sample regularly to at least a depth of 18 inches, particularly during the period from 4-5 leaf to flowering, when studying the relation between mineral nitrogen and crop growth. The data suggest that the response of wheat, as measured by grain yield and protein content, to the higher levels of mineral nitrogen in the improved soils of southern New South Wales is determined by soil moisture levels, particularly in the post-flowering period.

Lamb Growth

Pasture production, ewe and lamb growth, ewe wool production and diet quality were studied on lucerne-subterranean clover pastures at Wagga Wagga, New South Wales. Lucerne was sown at rates of 0.75 to 3.0 kg/ha, and the pastures were rotationally grazed with Border Leicester x Merino ewes at 9.6 or 12.7 sheep/ha, the ewes lambing in August- September. Lucerne density declined by 45% over the 3 years on all treatments. The clover cultivar sown, Woogenellup, had low persistence, particularly at 12.7 sheep/ha. The density of lucerne had little effect on annual wool and lamb production, although the ewes grew faster on the denser lucerne in summer and the sparser lucerne in winter. At 12- 7 sheep/ha, there was an extra 19% total lamb weight by the end of November and an extra 22% of finer wool (1 �m) annually, but the fleeces had a higher proportion of wool tenderness. The major limitations of the lucerne-subterranean clover pastures to sheep production were the low quality of the diet in early summer, and low pasture production in late winter. In early summer the lucerne was rapidly consumed, leaving only moderate quality clover and grass residues, which limited lamb growth, while in winter pregnancy toxaemia occurred, fleeces were tender and wool growth was low, particularly during a drought in 1976.

2 different rotations, wheat-lupin (WL) and wheat-subterranean clover (WC) were compared under 2 different tillage systems, direct-drilled (DD) and conventional tillage (CT) at a 10-year-old experimental site in Wagga Wagga, New South Wales. Significant differences in soil organic carbon concentration between the 2 rotations were found only under the DD systems; soil under WC rotation had a significantly higher organic carbon in the top 0.05 m than the WL soil. No such difference was detected under CT. Under both tillage systems, WC soil had lower pH (by 0.32 unit), with accompanying lower exchangeable magnesium but higher extractable aluminium than the WL soil in the top 0.05 m. Despite similar earthworm population and surface macroporosity, there was evidence suggesting that, under direct drilling, 10 years of WC rotation had reduced the subsoil water storage after summer fallow and reduced the effective rooting depth of wheat when compared with the WL rotation. These had not resulted in difference in wheat yield between the rotations even though a smaller average grain size was found under WC rotation in the 1990 season.
