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 …

Trials in Progress. Only four grazing trials were continued in 1976. The pasture species and management trial at Moora (68M023) required a disproportionate amount of available work time. About 6 man-months were spent in completing the fencing, repairing and modifying the water system and increasing the working efficiency of the experiment. Sheep were reintroduced to the trial early in June.

Experimental Summaries - Plant Research

Observations and measurements were made on 10 grazing trials and 11 small-plot legume species trials in 1974. Three of the grazing trials were under crop, two of them concluding low oestrogen species trials which had been grazed since 1969, and one of them, 68M023, West Moora, as an interval between pasture phases. The small-plot trials dated from 1970 or later and on most of them half of each plot could be grazed by sheep and half was protected. These trials have continued to supply useful information on the suitabiliy of cultivars to soil and climate and will be the subject …

The Doublegee Problem In Western Australia, D J. Gilbey

Journal of the Department of Agriculture, Western Australia, Series 4

Doublegee is native to South Africa and is now naturalised as a serious weed of crops and pastures throughout the temperate areas of Australia.

Doublegee was introduced for cultivation as a vegetable by English migrants to the Swan River Colony in 1830, and a bed of doublegees is known to have been sown at Mr. J. Phillips' property on the Canning River in 1833. However, the plant soon became a troublesome weed and its name was changed from Cape spinach to Tanner's curse and later to doublegee.

More than 180 doublegee seedlings per square metre have been counted in a …
