Effect of sowing date, nitrogen application rates and timing on grain  yield and quality of six wheat varieties - Barellan 2015 locations
Aims

This experiment is one in a series of nitrogen experiments aimed at establishing variety responses to different nitrogen application rates and timings.

Key messages

Key findings

 Sowing time had a huge effect on grain yield.

 Delaying sowing time reduced grain yield, TOS 1 yielded 4.84 t/ha and TOS 2 yielded 3.55 t/ha.

 Suntop was the highest yielding variety, 4.47 t/ha.

 Lancer was the lowest yielding variety, 3.73 t/ha.

 Given profitability and return on investment 40 kg N/ha at sowing was the ideal rate of nitrogenSowing time had a huge effect on grain yield.

Delaying sowing time reduced grain yield in all varieties across all nitrogen treatments.The effect of nitrogen varied between the two sowing times. The ideal target rate of nitrogen, given profitability and return on investment was 40 kg N/ha.
