Gross Income per Hectare in Trials
RVT Series 3 (RVT3) was a multi-region trial conducted on behalf of the Australian industry. It included a total of 30 genotypes as follows
- Five industry Standards. The Standards at most sites were HAES 246, HAES 344, HAES 741, HAES 816 and HV A16. The exceptions were at Wirrawilla HAES 246 and HAES 741 were swapped with HAES 842 and HV A268; at Childers HAES 344 was not available.
- 20 industry selections
- Five Hidden Valley selections A376, A403, A422, A447 and A538 discussed in these pages.
Using the basic measure of Gross Income/Ha/Yr calculated from RVT3 data years 4 to 9 as basis for comparison, HV A422 performed as follows
- Averaged across all sites it was $2,628/Ha ahead of the Standards by year nine of the trials.
- Ahead of the Standards at all sites except Wirrawilla and Childers.
- Acheived one site-specific Top 5 ranking, three site-specific Top 10 rankings, and an all-sites Top 10 ranking
