Introduction Lucerne Australia has received Rural Industries Research and Development Corporation (RIRDC) funding to undertake an independent fertiliser trial on both dryland and irrigated lucerne seed systems in the South East of South Australia. It commenced in 2012 and the duration of the project is a minimum three years, potentially five years. It will provide a clear picture of determining what fertiliser products will deliver the maximum benefits for lucerne seed producers with the primary focus on seed yield. There is an extensive variety of fertiliser products ranging from traditional granular products to liquid to a variety of compost mixes. The products are triple replicated on both an irrigated site and dryland site, totalling 180 plots. The expected outcome of this project is for the lucerne seed industry to benefit by being able to cost-effectively fertilise lucerne for seed crops, thereby finding the optimum investment level of fertiliser applications required to maximise seed yields and gross margins. Project Objectives • Determine which fertiliser treatment will deliver total maximum seed yield. • Evaluate which treatment will deliver the most economic seed yield in terms of yield output for
dollar input. • Evaluate if there is a relationship between foliage and seed yield. • Measure soil fertility using soil and sap tests. • Determine the accumulated effects of the four above objectives in a long-term production
phase. • Observe any side effects associated with the different types of fertilisers on lucerne seed
production – this will be observation only and may assist with identifying possible problems with different treatments for the future.
• Deliver objective, accurate and timely results to industry in an accessible format.

S econd Y ea r R esul ts The trial has achieved its year two objectives; these include soil tests, sap tests and fertiliser applications in accordance to rates, timeliness and accuracy. H arvest occurred at the optimum time and in a timely manner, in accordance with the project plan. Treatments which performed well in 2012-13 again performed well in 2013 -14 in both the Dryland and Irrigated sites. Likewise, a number of treatments which under-performed in 2012-13 did the same again in 2013 -14 . W hilst there appears to be differences in seed yield across treatments, this variation is not statistically significant at this point in time. H igher yields on the Irrigated site indicate yield is able to absorb the input costs resulting in minimal variances in the relative gross margin. V ariation in the establishment of the lucerne throughout the Dryland site is having an effect on the data analysis with particular reference to higher than desired CV ’ s, but this is being monitored. W e look forward to seeing the trial being developed further for another one-to-three years, seeing treatments perform and trends continue with strong statistical data to enable lucerne seed producers to make informed choices for the greatest return on investment. Lucerne Australia would like to thank all those involved in this trial, including RIRDC, P roject Manager P eracto SA, B recon P roprietors (landowners) and the fertiliser companies supplying product and working to the trial guidelines.

Note:
• Letters accompanying data within table 4 are ‘ letters of significance’ . Although data may appear numerically different, all treatments with the same letter of significance cannot be considered significantly different.
• Seed yield has been measured and displayed on the basis of 9 9 .9 % purity of cleaned seed. • Relative G ross Margin is calculated based on a cleaned seed price of $ 5 -00/ kg. P lus an application cost
of $ 5 -00/ ha for granular, $ 11-00/ ha for liquids and $ 20/ ha for composts, but excludes freight. N o other cost associated with producing the seed are factored in as these are considered constant across all treatments within the trial.
• The variability in plant establishment across the site is influencing the statistical analysis. This is being reflected in the much higher than desired CV for clean seed yield.

• Letters accompanying data within table 8 are ‘ letters of significance’ . Although data may appear numerically different, all treatments with the same letter of significance cannot be considered significantly different.
• Seed yield has been measured and displayed on the basis of 9 9 .9 % purity of cleaned seed. • Relative G ross Margin is calculated based on a clean seed price of $ 5 -00/ kg. P lus an application cost of
$ 5 -00/ ha for granular, $ 11-00/ ha for liquids and $ 20/ ha for composts, but excludes freight. N o other cost associated with producing the seed are factored in as these are considered constant across all treatments within the trial.
