Trial 89NA61
Location: Duranillin
In this site we would expect a very large response (40 to 50% ) to phosphorus.
History:
The site was chosen because of the patchy and poor pasture production. The poor areas tend to have more suckling clover than the good areas. The pasture was legume dominant.
Treatments were applied on April 16, 1989.

Trial 89BA33,
Location: Badgingarra
Based on a 1.5 t/ha potential yield, the strategic treatment was planned to be 120 kg urea/ha 4WAS. However, the crop was poorly established and so NH4NO3 was used in the hope of getting better tillering than would be possible with the slower release urea source. Gambling on equal dollars to urea for 2/3 N, but believe that twice as effective.
DAP was used to place nitrogen with the seed in case there was no rain of significance after seeding. This nitrogen (only 5 kg/ha) was probably lost with the rains of 20-28/7/89 (50 mm). Urea …

Trial 89TS38
Location: East Latham
The very low seed yields are a reflection of the dry winter conditions experienced in 1989. The Rose (T. hirtum) and Cupped (T. cherli) clovers appear to be a more promising option for this difficult soil type compared to other species. Paros yellow serradella performed well considering the trial site is located in a very dry area. The burr medics would not be an option on these acidic soil types because of nodulation failure; which should become evident in the regenerating swards.

Trials : 88BY26, 88PE34, 88MD35
Control of Rhizoctonia solani infection of potato stems and daughter tubers was demonstrated by preplanting applications of tolclofos-methyl (RIZOLEX TM) to either cut or round seed tubers. Yield of tubers from cut seed treated with Rizolex was increased over that of cut seed cured before planting bu not when seed was cut and planted the same day. Crops grown from round seed treated with Rizolex yielded higher than from untreated round seed.
Surface sterilization of seed tubers with Sodium hypochlorite was effective in reducing stem damage but not in reducing daughter tuber sclerotes. This indicates …

Current recommendations for pasture species in the medium rainfall zone has not included species mixtures for paddocks with varying soil types. These trials (three in total) are designed to test the hypothesis that legume species mixtures are more productive and persistent in the long term than monocultures, across three soil types and three different cropping/pasture rotations (continuous pasture, 1 year pasture : 1 year crop rotation, 2 years pasture : 1 year crop rotation).
