1972 - Part 3 - Lupin Cultivar Comparison, G H. Walton Jan 1972

1972 - Part 3 - Lupin Cultivar Comparison, G H. Walton

Experimental Summaries - Plant Research

The 1972 experimental results provide a good comparison between Unicrop and Uniharvest lupin under low rainfall conditions. While most trial results have to be examined in the knowledge of low rainfall confounded with high weed competition, some useful and practical conclusions can be drawn. Trials - 72MO10, 72MT33, 72GE11, 72GE12, 72GE13, 72GE14, 72LG7, 72LG10, 72NO9, 72NO10, 72TS10. Other grain legume variety trials which were not harvestable for lupin varieties - 72AL10, 72ES9, 72LG8, 72LG9, 72NA10, 72NA11, 72TS11, 72WH9,


A Report On The Condition Of The Gascoyne Catchment, D G. Wilcox, E A. Mckinnon Jan 1972

A Report On The Condition Of The Gascoyne Catchment, D G. Wilcox, E A. Mckinnon

Resource management technical reports

Severe flooding in Carnarvon followed heavy rains on the Gascoyne Catchment in February 1961. The flooding and erosion were extensive enough to suggest that run-off from the catchment was excessive. Lightfoot (1961)* reported that excess run-off was due to degradation of the catchment area. This report will describe the catchment area in terms of the degradation of its rangeland and its susceptibility to erosion.
