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.

Supply Water

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.

Phosphatic Fertilizers

SummaryNitrogen is the most important, and usually the only, nutrient necessary for high yields of rice in the South Western Riverina of N.S.W. Inclusion of a legume pasture phase in the rotation is a very effective method of improving the nitrogen status of the soil, but small additions of artificial fertilizer at sowing may still be necessary for maximum yields. The addition of phosphatic fertilizers is rarely necessary, except on a few isolated virgin soils, and where pastures are included in the rotation ample phosphate for the rice crop is usually present as a residue from topdressing. Potash and trace-elements do not improve rice yields in this area.
