Contributor Central West Farming Systems
Trial location(s) Merriwagga, NSW
Long term tillage and rotation trial locations
Aims

To compare no till farming techniques against conventional farming methods over 5 different cropping
rotations.

Key messages
  • No till treatments, for all rotations, were slightly higher yielding than the conventional tillage
    treatments for wheat. The yield of peas, in rotation 2, was very low in this trial as a result of
    the season and Sakura damage.
  • Rotations including a fallow, such as the WFW treatment, had lower weed numbers compared
    to continuous cropped rotations. The continuous wheat rotation, both conventional and no till
    treatments, had a large number of ryegrass, even with Sakura.
  • Profit and income for 2015 was highest in the no till wheat/ley/fallow/wheat rotation, and lowest in Rotation 2.
  • 17 years of no till wheat on wheat is still second for profitability.
