Time Of Harvest

To test the potential suitability of ten tomato varieties in the Murrumbidgee Irrigation Area of New South Wales to mechanical harvesting, the yields from 'once-over' harvests were compared with the yields from a harvest consisting of four pickings at weekly intervals. In a second experiment the effect of plant spacing, time of harvest, and side-dressing with nitrogen fertilizer were studied for the most promising varieties from the first experiment. The varieties Roma 884, VF145-22-8, and VF145 held their crops for prolonged periods without deterioration and so showed potential for mechanical harvesting. High planting density gave the highest yields from a single picking, and later picking and nitrogen side-dressing also increased yield.

Nitrogen Fertilizer Rate

Two experiments were done at the Yanco Agricultural Research Centre, New South Wales, in 1978-79 and 1979-80 to measure the response of long grain rice, cv. Inga, to rates of nitrogen applied at two different times. The highest yields were recorded when the nitrogen was applied at panicle initiation. Increasing the rate from 100 to 200 kg N/ha at panicle initiation had no effect on grain yield. When the nitrogen was applied earlier, just before permanent water, yields were highest at 50 kg N/ha and declined at the highest rates (150 and 200 kg N/ha). This negative yield response was mainly due to a drop in the percentage of filled florets, and occurred despite an increase in panicle number.

High Production

Two phalaris hybrids (Siro 11 46 and allopolyploid) and the parent lines (Phalaris aquatica and P. arundinacea) were compared in monoculture with nitrogen fertilizer and in a mixed sward with white clover and lucerne. The experiment was flood irrigated and the effects of defoliating the swards at intervals of 21, 42 and 84 days were measured. The hybrid (Siro 11 46) was the most productive genotype at all defoliation intervals. Eighty one % of its annual yield occurred in spring and summer. This production imbalance renders Siro 11 46 unsuitable as the foundation of a pasture for high production throughout the year. The mixed sward produced more than the monoculture sward when defoliated every 21 or 42 days and there was increased production associated with increased defoliation interval. The monoculture sward was more productive than the mixed sward at an 84 day defoliation interval. The yield of Siro 1146 + white clover was 2.25 t ha-1 per 84 days, compared with a mean yield of phalaris + white clover of 1.78 t ha-1 per 84 days for the three other genotypes. The results indicate that Siro 11 46 grown with white clover and defoliated approximately every 42 days would be a suitable alternative pasture to Paspalum dilatatum and white clover in the two-pasture system used in irrigation areas of southern New South Wales. The problems of low acceptability and suspected toxicity of Siro 1146 are discussed.

The chemistry of shallow groundwaters in the Murrumbidgee Irrigation Area of New South Wales, Australia, is examined in terms of the degree of saturation with calcium minerals. Many water samples were found to be saturated with calcite, especially when brought into equilibrium with atmospheric CO2 pressures; gypsum saturation was found more frequently from regions having waters of high ionic strength. A thermodynamic chemical model is used to describe the effects on water 'quality', for irrigation purposes, if the groundwaters are to be reused in mixtures with irrigation supply water. A tentative classification in terms of salinity and sodium hazard is presented and a simple relationship between both hazards has been derived. A potential exists for using between 25% and 95% groundwater in mixtures with supply water for irrigation, depending on the initial salt concentration.

Feral mice from western Victoria, the Murrumbidgee Irrigation Area and the Northern Tablelands of New South Wales, and the Darling Downs of south Queensland, have been infected with ectromelia virus in a laboratory. There is no evidence that the virus is endemic in the feral mice. The infectivity of ectromelia is similar in all groups of feral mice, and in laboratory mice. The lethality of the infection is high in the Victorian mice, whereas mice from the other regions have moderate to high levels of innate resistance. Possible consequences of the release of ectromelia, to prevent or terminate mouse plagues, are discussed.

Two factorial field experiments, comparing the effects of a range of seeding rates and levels of nitrogen fertilizer on the winter and early spring yield of rape (Brassica napus CV. Dwarf Essex) sown in early autumn, were conducted in two successive years near Orange (33.2�S, 149.1�E), New South Wales. Average annual rainfall is 34 inches and winter mean temperatures range from 42-45�F. Seeding rates of from 9 to 15 lb an acre and nitrogen fertilizer at 80 lb N an acre at seeding gave near optimum winter and early spring yields. This combination gave a three-fold increase in yield over sowings at 3 lb an acre without nitrogen fertilizer. The responses to seeding rate and nitrogen were independent in winter, but these factors interacted to affect yield in early spring. The dry matter content of rape varied between 11.5 and 19.3 per cent and was generally unaffected by seeding rate, but tended to decrease slightly with increased nitrogen level. Nitrogen percentage, which fluctuated between 2.18 and 3.61, was little affected by increased seeding rate and generally showed a small increase with increasing levels of applied nitrogen.

Applied Nitrogen

In a series of five experiments in the irrigation areas of N.S.W., currently grown rice varieties were sod-seeded and compared under several rates of seeding and levels of applied nitrogen. There were no differences between varieties in their adaptability to the sod-seeding practice. Seedling survival was poor but higher seeding rates increased yields in only one of the four trials where they were tested. Responses to nitrogen fertilizer at seeding were small in the two experiments where it was included, but in one, 80 lb N per acre increased yield from 10,872 lb/acre to 12,292 lb/acre (P<0.05).
