Competitive wheat seeding systems for weed management and profit at Binnu in 2013 locations
Aims

To identify if twin row seeding systems and adjusting seeding rate will; 1)Increase the competitive ability of wheat in weedy situations and reduce weed seed set, 2)Increase the profitability of wheat production through increased yield and reduced costs of inputs.

Key messages

Magenta yeilded higher than Mace in Both seeding systems.

  • Single row yielded higher than twin row at Binnu, also looked much healthier (better) through-out the season. This has not been a consistent observation in other research trials. Likely cause is poor P nutrition due to fertiliser placemnt in twin row and low P site.
  • Increasing seeding rates reduced the yield potential of Magenta. In contrast, plant desities of 150 plants/m2 were the most productive for Mace.
