Delaying top-up nitrogen (N) applications until canola crops are flowering is unlikely to incur big yield or oil production penalties in lower-rainfall parts of the Western Australian grainbelt... Mr Seymour says at the majority of sites across the two years, delaying N application until eight or 12 weeks after sowing (near to flowering) or splitting applications produced similar yield results to earlier times of N application... Mr Seymour says splitting applications to 25kg N/ha at sowing and 25kg N/ha eight or 12 weeks later had a better effect on oil and yield than applying a single dose of 50kg N/ha near flowering...

Hybrid canola lifts mallee yields.. Improved hybrid genetics are allowing growers in low-rainfall areas to better match nitrogen applications to yield potential in canola crops as the season unfolds... DAFWA Esperance senior research officer Mark Seymour says the results indicated hybrid RR lines could provide opportunities for growers in the region to use low rates of nitrogen at seeding, then monitor the season and add more nitrogen as needed to reach optimal yield...
