Grass Sward

The use of a herbicide to restrict competition from an existing grass sward during the establishment of sod-sown Glycine javanica L. was examined in the Lismore district of New South Wales. Following application of a herbicide containing 27.7 per cent acid equivalent (a.e.) of the sodium salt of 2,2 DPA (2,2- dichloropropionic acid) and 12.5 per cent a.e. amitrole (3-amino-1,2,4 triazole) yields of G. javanica were proportional to the rate applied, for rates up to but not greater than 7.5 lb a.e. an acre. Yields from the successful herbicide treatments were of the order of 45-60 per cent of the cultivated seedbed. However, when sod-sown into an untreated sward, glycine virtually failed to establish. Weed growth was negligible in plots treated with a herbicide but was substantial in the cultivated seedbed. The application of these findings is discussed.

Growing Conditions

Six experiments were done in northern New South Wales over three seasons to study the effect of weeds on the yield of dry-land grain sorghum and methods of weed control. The relation between crop row spacing and weed control by inter-row cultivation or atrazine (2-chloro-4-ethylamino- 6-isopropylamino-l,3,5-triazine), or both was studied. Where the site yield was high because of favourable growing conditions, an increase in the crop row spacing reduced yield. At low yielding sites, an increase in the row spacing increased yields. At most sites, weed growth was greater with wider row spacings, which resulted in a larger reduction in crop yield where weeds were not removed. Inter-row cultivation reduced weed growth to less than half that of the unweeded controls. Pre-emergent atrazine gave good weed suppression, generally reducing weed growth to less than 10% of the unweeded control when applied at 2.5 kg/ha active ingredient. Post-emergent atrazine was much less effective. Inter-row cultivation combined with a band of pre-emergent atrazine over the crop row was as effective in weed control as an overall spray of pre-emergent atrazine.

Western Division

The semi-arid to arid Western Division of New South Wales has suffered significant levels of land degradation due to overstocking by domestic animals and rabbits. Three major forms of land degradation are identified, soil erosion, woody weed growth and pasture quality decline. Restoration techniques developed and applied by the New South Wales Soil Conservation Service are presented and discussed. The successful techniques presented are contour furrowing and waterponding for sheet eroded or scalded areas, fire and blade ploughing for woody weed control and grazing management to reverse pasture decline. The lack of knowledge on pasture species responses to grazing management stimuli is highlighted.

The Difference

In 4 consecutive years (1980-83) on a red earth near Yass, New South Wales, 9 fertilizer treatments were applied annually to wheat which was either sown into conventionally cultivated seedbeds or direct-drilled into previously uncultivated seedbeds sprayed with herbicide. Treatments comprised 1 unfertilized control, 4 levels of P and at a moderate rate of P, 2 levels of S and 2 of N. The same fertilizer treatments were applied to each plot throughout the 4 years. The response to P was substantial, with yield increases up to the maximum rate of 37 kg of P/hathinyear. Average grain yield over 4 years was 3.2 t/ha at 37 kg P/ha and 0.5 t/ha without P. With fertilizer and grain prices that applied over the 4 years, these responses were highly profitable. There was a response to N in 1983 only (18 kg of grain/kg N) and a small response to S in 3 of the years. Yields were 17% higher under direct drilling in 1980, probably because of grassy weeds in the conventional cultivation plots. In 1981 there was no difference between the 2 tillage treatments, and in 1982-83 yields averaged 15% less under direct drilling. Although the difference between the yield of direct-drilled and conventional cultivation treatments were relatively greater without or at low P than at the highest P level, this interaction was not statistically significant.

The effect of three rates of glyphosate (1, 3 and 5 kg a.i. ha-1) and two of 2,2-DPA (21 and 33 kg a.i. ha-1), each applied in October 1972, January 1973, April 1973 and July 1973, on serrated tussock and associated improved species (Phalaris aquatics, Trifolium repens, T. subterraneum) was ascertained in an experiment near Bathurst, New South Wales. The effect of the herbicide treatments on the improved species was measured in October 1973 and the percentage kill of serrated tussock recorded in May 1974. Increasing the rate of glyphosate increased the percentage kill of serrated tussock (up to a mean of 77% with 5 kg a.i. ha-1) ; time of application had no significant effect on percentage kill. No glyphosate treatment resulted in a commercially acceptable kill of serrated tussock (above 90%). Thus the herbicide was inferior to 2,2-DPA which produced a 95% kill when applied in summer. P. tuberosa was more tolerant of glyphosate and 2,2-DPA than serrated tussock and recovered from all treatments. T. repens and T. subterraneum recovered from glyphosate and 2,2-DPA applied in summer. Thus it proved possible to selectively remove a large proportion of a serrated tussock infestation with 2,2-DPA or glyphosate, applied in summer, without permanent damage to the associated improved species.
