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.

However, in the 1972 season, in field trials, the number of Clipper Barley plants emerging was reduced by urea …

Part 5 Comparison Of Genetic Components In Lupin Species, G H. Walton

Experimental Summaries - Plant Research

Influence of genetic components on harvest index. (note the conclusions from these results are especially subject to Statistical Analysis) 1. At three sites out of the four, the acquisition of 'early' gene(s) improved the harvest index. Mount Barker was the exception to this. This was true for both the cosentini, albus and angustifolius varieties. In 1971,when the spring was wetter than 1972,the plant maturity was much less of an influenceupon the harvest index. 2. The alkaloid content of the plant in L. angustifolius doesn°t seem to have a consistent influence upon the harvest index. This was the same experience irn …

The systematic investigations of the potential of the Ord area for irrigated farming began during the Second World War when the possibilities of damming the river were first examined, initial soil survey was carried out, and agricultural experiments started. The Kimberley Research Station was established on its present site in 1945. A year later the State and Commonwealth Governments agreed to finance and operate the Station jointly, with CSIRO and the Western Australian Department of Agriculture being responsible for research.

The construction of the main dam designed to store 5,675 million m" ( 4.6 million acre feet) was completed in …

Bulletin No 3768 - Submitting Plants For Disease Identification, M D. Marcley

Bulletins - 3000 - 3999

THERE are several important points to remember when submitting plant material for disease identification by the Department of Agriculture's Plant Pathology Branch.

Firstly it is very important to collect a suitable sample because it is very difficult to determine the cause of a plant disease by looking at a completely dead plant. The sample should include the entire plant (before it is completely dead) including roots and soil. Then all the effects of the disease can be seen. For example leaf yellowing, dead areas of the stem, collar rot, root rot, eelworm damage, and disease of the water and food …

During 1970 interest in the small ungrazed Legume Species Trials was reduced to ten trials located in the more troublesome areas. Five of the trials are on the sandy soils of the Midland Plain three trials are in Merredin-Southern·cross region, one is on deep sand at Tincurrin and the other is at Pindar. All thesites are sandy soils on which the sub clover strains appear to perform the best. The newer trials are investigating the value of sub clover cultivars such as Northam A,Mt Helena A, Shenton Park A, and Daglish. These trials will be the subject of a special …

SUBTERRANEAN CLOVER INOCULATION EXPERIMENTS Badgingarra and Newdegate Comparisons between Rhizobium trifolii strain WU290 and possible replacement strains were continued. The work was conducted for the following reasons 1. The need for information on "back-up" strains particularly since the inoculant manufacturers had experienced difficulty in producing high-count peat cultures of WU290. 2. Strain CC2480a had proved very satisfactory in the Eastern States. Although it did not show up to advantage under our conditions in 1968,further testing was indicated. 3. The need for information on inoculation needs on old land.

Soil types examined were the very gravelly soils (5 reps, 4 sites), sands or loamy sands over gravel or clay (3 sites) and sandplain soils (3 reps, 2 sites). In all cases except one, fertiliser history was not reliable, but in every case well over one ton of super had been applied. over a period of over 15 years.

Anhydrous Ammonia, M G. Mason

Experimental Summaries - Plant Research

Anhydrous ammonia, as the name infers, is pure ammonia, It is kept in a liquid form under pressure and must therefore be stored in special vessels. When pressure is released it changes to gaseous form. Anhydrous ammonia is the most concentrated form of nitrogen fertiliser available. It has 82% nitrogen compared to 46% for urea, the most concentrated solid form of nitrogen fertilisers.

Trials carried out were:

1965 - 1967 Wongan Hills Research station (3)

2. To compare the merits of three sources of nitrogen for this purpose.
3. To determine the maintenance dressing of superphosphate under this system and the need for supplementary fertilisers.
