Fallow Re-Assessment, D Tennant

Experimental Summaries - Plant Research

Fallow re-assessment. I. 72M29. Location - Merredin Research Station II. Other fallow results. As part of the fallow re-assessment project, a study was made of results from all trials done since the early 1920's which either compared fallow with non fallow or examined other aspects of fallowing. Analysis of these data has led to an update of some of the rainfall - soil water storage - yield relationships presented in previous reports. On the basis of these rainfall-yield relationships and of relevant rainfall statistics we can make an assessment of the probable value of fallow at different locations; Merredin; Chapman, …

Barley Yellow Dwarf Virus In Barley And Oats (79mt20, 79pe13) Experimental Summary 1979, G D. Mclean, T N. Khan, M Grimm, J D. Sandow

Experimental Summaries - Plant Research

(1) Yield assessments have continued similar to those used in 1977 and 1978. Essentially, plants with symptoms typical of BYDV are marked in the early spring as well as a similar number without symptoms. Yield differences were obtained both for Clipper Barley and an oats variety. (2) Two pilot experiments using viruliferous aphids were carried out at Mount Barker (79MT20) and at South Perth · (79PE13). Both Rhopalosiphum padi and R. maidis were used. Infection at Mt Barker failed, and therefore no data is presented. The Perth experiment was planted on August 31, 1979. The original plan was to have …

Drill-sown trials - Seed yields from the trials varied from good in the southern wheatbelt to very poor in the northern areas. Test samples were taken from trials 77GE32, 77GE40 and 77GE41 in the Pindar and Tardun districts, 77ME22 at Koorda and 77TS25 at Perenjori but the quantity of seed did not warrant yield assessment.

Lupin Trials, J Moore

Experimental Summaries - Plant Research

Trials in lupins this year concentrated on testing herbicide for post emergence use in lupins. Of the 20 herbicides tested 12 did not cause significant decreases in crop density and/or yield. However, weed control was often poor and the herbicide phytotoxicity tended to vary between sites. (Chapman, Badgingarra and Avondale). The Chapman and Avondale trials were not harvested because of drought. Trials in 1978 should determine if any of the herbicides tested can safely be recommended. Lupins - summary.

Cereal Foliage Disease Survey, T N. Khan, A. G. P. Brown

Experimental Summaries - Plant Research

Cereal Foliage Disease Survey A dry season reduced disease to insignificant levels (as measured by this survey) in all areas except the south west. Late rains may have produced some damage to wheat by S. nodorum however but this was probably confined to southern areas. In barley net blotch which has been declining re appeared a major disease in 1977 excepting high rainfall areas, where scald continued to be severe. The level of scald infection was considerably lower which may be associated with relatively higher temperatures and low rainfall. Variety Clipper continued to show high degree of tolerance to net …
