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 …

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.

Minimum tillage trials 1977. Locations: Wongan Hills R.S., Avondale, Merredin, Mt. Barker, Esperance. Sites: At each station two sites were used, the first was under crop in 1976 and the trial will be repeated each year on the same area. The second site was under pasture in 1976 and was due to be cropped in 1977 as part of the normal district practice. The trials will be planted on a similar pasture site in 1978. Results. Apart from crop yields, weed counts (before spraying) and crop plant numbers were taken. Other measurements were made by various research officers and reported …

Longevity Of Doublegee Seed Under Continuous Pasture, D J. Gilbey Jan 1977

Longevity Of Doublegee Seed Under Continuous Pasture, D J. Gilbey

Experimental Summaries - Plant Research

Locality: Avondale, Wongan Hills and Chapman Research Stations. Background. Since 1974 pegged areas on the three research stations have been under continuous pasture and have been sampled annually to study the fate of the viable doublegee seed population. Each site was sprayed for doublegee control in the growing season before the first samples were taken in late summer of 73/74. The sites were again sprayed in the 1974 growing season except for Wongan Hills. The Wongan Hills site was cropped in 1976 and no further data is available. 74C7, 75WH65, 75WH66, 76AL11, 76C9, 76C6, 77C3, 77GE9, 77LC26, 77ME28, 77M028, 77N034, …
