1973 Time Of Planting And Rate Of Seeding On Lupin Yield, G Walton

Experimental Summaries - Plant Research

Of the four time of planting trials two definitely showed superiority of earlier seeding (73BA5, 73E6). The two trials in the Southwest (73BR14 and 73MT7) gave highest yields with June sowing compared to May. Three trials (73BR14, 73E6 and 73BA5) appear to have a Variety x Time interaction for plant density, but no definite trend for either Uniharvest or Unicrop although later sowing reduced plant density. Seeding rates in excess of 82 kg/ha gave the highest yields in all trials. The rate of seeding experiments (73BA5 and 73MT7) show that the best crop density for yield (graph) lies between 8 …

Summary Of 1972 Seasonal Results "Decide" Superphosphate Rates On Pastures, J. W. Bowden

Experimental Summaries - Plant Research

A total of 53 pasture trials were topdressed. Of these, 37 trials were quantitatively assessed at different times during the growing season. Of the 15 wheat trials sown, only four trials gave useful results because of multiple drilling techniques used on most trials. Until the trial results have undergone comprehensive statistical analysis, no conclusions can be drawn. about the levels of response or "optimum" rates of superphosphate application at individual sites. However, because of the very short growing season in 1972 responses were generally poor. It appears that nil superphosphate application would have been optimum for animal production in the …

1973 Rates Of Phosphate On Lupin Yield, G Walton

Experimental Summaries - Plant Research

Comments on Results - New Land sites (Graphs 1, 2) - The three sites were very responsive with the point of inflexion about 600 kg/ha super rate (similar to 1972 result). The seed x super rate interaction shows the quicker response to super with higher seeding rates. Low Super Bank (800 kg/ha) (GRAPH 3) - The two sites showed very little response to super applied. On the Eradu sandplain no response to super for either Unicrop or Wheat. On the Watheroo yellow sandplain (73M015) the two lupin cultivers and the wheat gave different responses. High Super Bank (>1 OOOkg/ha) …

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 …
