Experimental Summaries - Plant Research
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 …

Rhizoctonia Control In Potatoes And Potato Resistance To Powdery Scab., R M. Floyd
Experimental Summaries - Plant Research
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).

Inoculated and lime pelleted seed was hand sown into 3m rows at 0.25 g/m. All the medics were inoculated with WSM 540 which may have been less effective with some of the M. littoralis and M. tornata varieties. The 1988 season was very good in terms of frequency and amount of rainfall which is reflected in the high seed yields compared to 1987.

Half the trial site was cultivated to 30cm at the break of the season and the whole site was normally cultivated. Weeds were then sprayed with Roundup at 1 1/ha prior to seeding with an eight run cone seeder. The plots were kept weed free during the year by hand weeding. The root distribution was calculated from soil cores taken in 20 cm increments on 20 August. Aphid cortrol consisted of spraying every two weeks with Pirimor at 140 g/ha between July and October.

The plots were hand sown at 2 g/m2 of inoculated and lime pelleted seed. The medics were inoculated with WSM540 which may have been ineffective on some of the M. littoralis and M. tornata varieties. The time taken to form ripe pods was monitored to gain some extra measure of maturity besides flowering time for comparing wide ranges of species. The ripening time involved was very similar over all the varieties, averaging out to 44 days after the flower opens. What appears to be a more important factor when considering maturity is the …
