The Grazing Value Of Medicago Murex., C. M. Saunders Jan 1989

The Grazing Value Of Medicago Murex., C. M. Saunders

Experimental Summaries - Plant Research

Trial 88KA92

Location: Potts Road, East Kojonup.

At present, limited information is available on the grazing value of Medicago murex cv. Zodiac on sheep live weights and wool growth. This trial was designed to provide data on the relative performance of sheep grazing Zodiac compared with the recommended subterranean clovers (Junee/Seaton Park) in the > 450mm rainfall zone in WA.


Cultivar Evaluation On Low Rainfall Heavy Textured Soils., Bradley Nutt Jan 1989

Cultivar Evaluation On Low Rainfall Heavy Textured Soils., Bradley Nutt

Experimental Summaries - Plant Research

a. Trial 88GE34

Cultivar evaluation in machine sown plots.
Location: NMRS

The higher seed yield of Serena compared to the other cultivars resulted in better early forage .production as well a legume dominated pasture.

b. Trial 88TS 63 and 88TS 65

Wheat yields following pastures.
Location: 88TS63 - Perenjori and 88TS65 - Three Springs.

There was no response to nitrogen in either biological yield or grain yield of wheat sown over volunteer based pasture at the Three Springs site. All pasture treatments resulted in similar wheat yields except for Sava because of poor control of the snail medic under the …

Location: Tenderloin, Brand Highway, Regan's Ford.

New Block Badgingarra Rs Late Time Of Seeding., J. W. Bowden, R. J. Lunt

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 Jan 1989

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 …
