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 …

Minimum Tillage Trials 1977, G. A. Pearce

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

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, …

Bulletin No 3993 - The Control Of Saffron Thistle, G. A. Pearce

Bulletins - 3000 - 3999

Saffron thistle is a primary noxious weed and is widespread throughout the drier parts of Western Australia. When growing in pasture its prickly growth habit discourages animals from grazing amongst it so that its presence results in the loss of feed. In crops it reduces yield and results in dockage when seed is found in harvested grain.

1976 Sunflower-Safflower Irrigated Variety Trial 1976-1977, G J. Parlevliet

Experimental Summaries - Plant Research

In 1975/76 two varieties of sunflower, Hysun 10 and Hysun 20, as well as Safflower (Gila) were grown in a large alternative crop demonstration. Results were sufficiently good to warrant more and closer examination. This led to the present variety trial using varieties suggested by Mr. M. Poole. The aim was to evaluate six sunflower varieties and one safflower. The work was carried out in the light of reduced profitability of peas, beans and some fruit crops. This results in a number of growers having irrigation water and equipment under-employed. Other farmers are after a crop which will give them …
