Matter Production

Cultivars of lupin and field pea were grown at different times over 4 years on a red earth at Wagga Wagga, New South Wales, to assess the influence of sowing time on growth and production from each crop. The cultivars of field pea (Pisum sativum) included Dinkum, Derrimut, Dunn, and Maitland; lupins used were Lupinus angustifolius cvv. Danja, Gungurru, and Geebung, and either the L. angustifolius line 75A/330 (1989-90) or L. albus cv. Ultra (1991-92). When autumn rain was sufficient to allow sowing, highest yield and dry matter production of lupin were gained by sowing from late April to 19 May. Yields declined with later sowing, though high spring-summer rainfall in 1992 reversed the decline. There was little difference between Danja, Gungurru, and Geebung, but these were usually higher yielding than the semi-dwarf 75Al330 when sown early. However, Ultra produced higher yields than the L. angustifolius cultivars in 1991 and 1992, particularly under high rainfall conditions. Early-sown crops (late April-mid May) of field peas were often severely infected with black spot blight and, in 1 year, with sclerotinia. In 1992 these diseases devastated all cultivars when sown on 1 May. Sowing later markedly reduced disease infection but also reduced grain yields and dry matter when sown after late June. The semi-leafless, semi-dwarf cultivar Dinkum was usually the lowest yielding and displayed the highest incidence of black spot blight.

Semi Arid

Thirty-three species of butterflies are recorded from the Griffith district in the semi-arid zone of inland southern New South Wales. The butterfly community comprises the following structure: 19 species (58%) are resident; 7 (21 %) are regular immigrants; 2 (6%) are irregular immigrants; 5 (15%) are vagrants. Except for a few migratory species, most occur in relatively low abundance. Lack of similar studies elsewhere in western New South Wales precludes generalizations regarding the species richness, composition and structure of semi-arid butterfly communities. Comparison of the butterfly fauna with that from five other inland regions on the slopes and foothills of the Great Diving Range, revealed that the Griffith district is most similar in species richness and composition to that of Deniliquin and to a lesser extent Wagga Wagga and Cowra in the south, than with two regions in the higher summer rainfall area of the north of the State (Coonabarabran-Mendooran, Narrabri-Bellata). Overall, the butterfly fauna of inland New South Wales (total of 73 species, of which 49 occur in the southern regions) is depauperate compared with that recorded from the coastal/subcoastal areas east of the Great Dividing Range. Attention is drawn to the conservation significance of several vegetation types and habitat remnants in the Griffith district. Much of the native vegetation in the district has been extensively modified since European settlement due to excessive clearing for agriculture, resulting in a highly fragmented landscape for the conservation of native flora and fauna. With the exception of the lycaenid Candalides hyacinthinus Simplex, which is considered threatened locally, there is a general absence of narrow range endemic butterflies associated with mallee-heathland or mallee-woodland, possibly as a result of widespread land clearing practices of mallee vegetation in the past.

In 1985, experiments were conducted at 4 localities in south-eastern and central New South Wales, to assess the production potential of tagasaste. The results were disappointing: 2 experiments failed to establish because of soil waterlogging, while production from the other 2 sites was only intermittent. Annual dry matter production did not exceed 3 t/ha at Condobolin or 5 t/ha at Yass. Although survival of established plants was good, production was limited by prolonged dry periods at Condobolin and by low temperatures during winter at Yass. Tagasaste is costly to establish (up to $A500/ha) and difficult to manage. In our environments, conventional pastures or fodder crops which require simpler management would probably out-produce tagasaste at most times during the experimental period.

Applied Nitrogen

Three winter cereals (wheat varieties Songlen and WW 15, triticale variety Satu) were grown after cotton or summer fallow under three levels of applied nitrogen (0, 100 and 200 kg N/ha) at Narrabri, New South Wales. The cereals were sown on August 7, 1980 and growing season rainfall was supplemented by a single irrigation. Leaf area, total shoot dry matter production and ears per square metre were lower after cotton than after summer fallow, while grain yields of cereals sown immediately after cotton were 33% lower than those sown after fallow. Adding nitrogen increased leaf area, dry matter and grain yields of crops grown after cotton and fallow, but significant increases were not obtained with more than 100 kg/ha of applied nitrogen. Crops grown after cotton required an application of 100 kg N/ha for leaf and dry matter production at anthesis to equal that of crops grown after fallow with no additional nitrogen. The corresponding cost to grain yield of growing cotton was equivalent to 200 kg N/ha. The low grain yield responses measured in this experiment (1 8 and 10% increase to 100 kg N/ha after cotton and fallow, respectively) were attributed to the combined effects of late sowing, low levels of soil moisture and loss, by denitrification, of some of the applied nitrogen. The triticale, Satu, yielded significantly less than the two wheats (1 99 g/m2 for Satu c.f. 255 and 286 g/m2 for Songlen and WW 15, respectively), and did not appear to be a viable alternative to wheat in a cotton rotation.

Four ecotypes of hybrid Bermudagrass (Cynodon dactylon) were compared with common couch (C. dactylon) and kikuyu (Pennisetum clandestinum) at five sites in coastal districts of New South Wales. The sites were Grafton and Coaldale (Lat. 30�S), Mitchells Island (Lat. 32�S) and Richmond and Badgerys Creek (Lat. 34�S). Hybrid Bermudagrass ecotypes 6389 and 692 were established quickly at all sites while ecotypes 71 9 and 632 were satsifactory. Kikuyu was strong at all sites except Grafton but the rate of establishment of common couch was poor. At the frost-free sandy site of Mitchells Island, Bermudagrass ecotypes 719, 692, 6389, and 632 outyielded kikuyu by 75, 65, 65 and 35%, respectively. However, at Grafton and Coaldale, the highest yielding Bermudagrass ecotype, 719, had only 35% higher production than kikuyu. At the frost prone southern sites of Richmond and Badgerys Creek, the annual production of kikuyu was equal to that of ecotypes 719, 6389, 692 and 632. Common couch yields were equal to kikuyu at all sites except at Richmond. At Mitchells Island, the hybrid Bermudagrasses outyielded kikuyu in spring, summer and early autumn but in the late autumn kikuyu had equal and sometimes higher growth rates than the best Bermudagrasses. In winter, the growth of both species was negligible, although kikuyu, unlike the Bermudagrasses, did produce some new shoots at the base of the sward. Data on persistence under grazing were collected from only three of the sites but trends were similar to establishment. Ecotype 6389 had the highest persistence rating of the Bermudagrasses. Kikuyu failed at the poorly drained sandy site of Grafton but remained strong at the other sites. It was concluded that hybrid Bermudagrasses were of potential value for pastures in New South Wales, especially for sites with sandy soils and low frost incidence.

Seed Yields

Dry matter production and seed yields of a range of annual legumes grown in ungrazed swards were measured between 1966 and 1971 on seven sites in the low rainfall wheatbelt of central western New South Wales. Jemalong and Hannaford barrel medics (Medicago truncatula) were the highest yielding medic cultivars tested. Jemalong medic was slightly superior to Hannaford in dry matter production but seed yields were equal. The short season subterranean clovers (Trifolium subterraneum), Dwalganup and Geraldton, yielded much less dry matter and seed than the medics in most experiments. Although the mid-season subterranean clovers, Woogenellup and Clare, persisted for the duration of our experiments, their production was not as consistent as that of the medics, and plant densities decreased. The rose clovers (T. hirtum), Sirint and Kondinin, the cupped clovers (T. cherleri), Beenong and Yamina, and Snail (M. scutellata) and Paragosa (M. rugosa) medics did not produce satisfactory swards.

Matter Production

In southern New South Wales, Australia, grazing wheat during the vegetative and early reproductive growth stages (typically during winter) can provide a valuable contribution of high quality feed during a period of low pasture growth. This paper reports results from a series of experiments investigating the agronomic management of grazed wheats in southern NSW. The effect of sowing date and grazing on dry matter production and subsequent grain yield of a range of wheat cultivars was measured in five experiments in 2004 and 2005. In all experiments, results were compared with ungrazed spring wheat (cv. Diamondbird). Grain yield of the best winter cultivar was either the same or significantly greater than the spring cultivar in each of the five experiments. Within the winter wheat cultivars, there was significant variation in grain yield, protein content and screenings, depending on site and year with the cultivar Marombi out-yielding all others. Interestingly, this cultivar usually had the least dry matter post-grazing but the greatest dry matter by anthesis of the winter wheats. Generally, if sowing of the winter wheat was delayed, then the effects on yield were small or non-existent. The results are discussed with respect to the benefits of incorporating grazing cereals into cropping programs in the medium rainfall zone of southern Australia.

Methods Of Application

The dry matter production of a pasture of barrel medic (Medicago truncatula cv. Jemalong) under different rates and methods of application of superphosphate was examined, during 1971 and 1972, on a phosphorus deficient soil at Condobolin, New South Wales. The treatments were factorial combinations of four rates of superphosphate (0, 126, 376, and 753 kg ha-1) and four methods of application of superphosphate (surface spread i.e. topdressed, surface applied in bands, placed at 5 cm depth, and placed at 1 0 cm depth). The dry matter production and phosphorus uptake results demonstrated the effectiveness of subsurface placement of superphosphate, but relative ineffectiveness of surface application during the dry winters experienced. The results also showed that root development in the dry 0-2 cm zone was restricted compared with that in the deeper moist soil layers. Soil phosphorus tests showed that one year after topdressing phosphorus had not moved below the 2-4 cm depth layer, even at 753 kg ha-1 of superphosphate.

Seasonal yields and persistence of Hunter River and three introduced lucerne (Medicago sativa) cultivars (African, Du Puits, and Hairy Peruvian) were compared with two C.S.I.R.O.-bred lines, a hay type (C.1212) and a creeping type (Cancreep), over a five-year period between 1963 and 1968 under dryland conditions at Narrabri, New South Wales. After two years, Hunter River had significantly higher plant density than all other cultivars. By maintaining this superiority throughout the experiment, it was never exceeded in dry matter production in any season after the third summer. Spring yields of Cancreep compared favourably with Hunter River for three seasons, and there was little difference between most cultivars for four summers. Cancreep and Hairy Peruvian matched Hunter River in autumn-winter production for two seasons. In all cases decline in production during the third and fourth years is attributed to a lack of persistence in cultivars other than Hunter River.

Improved Pasture

A simple model for predicting pasture growth from climatic data was developed and tested against experimental data. The model was used to analyse climatic data from a 24-yr period (1950–1973) to elucidate the relative importance of soil moisture and temperature on the growth of improved pastures on the Northern Tablelands of New South Wales, and to predict the year-to-year variations in total pasture growth.Predicted yearly dry matter production varied between extremes of 5000 kg ha-1 yr-1 in 1965 and 14,000 kg ha-1 yr-1 in 1971. Soil moisture was the major factor limiting pasture growth from the beginning of October until the end of May, and temperature was the major limiting factor from the end of May to early October. During May and October there was a period when both factors had a similar probability of being the most limiting factor. Variations in soil moisture caused greater within-year variability in pasture growth than temperature except in April and September when variability caused by temperature equalled that caused by soil moisture. The significance of these effects is discussed.

The effect of sowing time on the growth, yield, and oil characteristics of irrigated sunflower was studied for 3 consecutive seasons at Leeton (34�28�S., 146�25'E.), in southern New South Wales. The hybrid cultivar Hysun 32 was sown at monthly intervals from late October to late January. Duration of growth from sowing to physiological maturity was reduced by I5 days when sowing time was delayed from late October to late December. Dry matter production at flowering was lowest from the late December sowing, and harvest index was always lowest from the late January sowing. Late October and late November sowing produced similar yields (>4 t/ha), but delaying sowing further to late December and late January reduced yields by 18 and 37%, respectively. Effect of sowing time on yield was mainly related to effects on seed number per head. Seed oil content averaged 50%, with the late November sowing producing the highest value in all seasons. To be confident of producing a linoleic acid level >62% as required for the margarine industry, sowing should be delayed until mid November.
