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

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 …
