Comparing break crop performance of break crops in the Mallee - Michael Moodie (MSF)

258 views

Published on

Trials were implemented to compare break crop productivity and profitability on major soil types in the northern South Australian Mallee. This information will help farmers in this region to select the most appropriate break crop for their farming system.

Comparing break crop performance of break crops in the Mallee - Michael Moodie (MSF)

  1. 1. Michael Moodie Comparing break crop performance of break crops in the Mallee
  2. 2. Project Aim: To improve our understanding of break crop productivity and profitability across seasons and soil types in the Mallee First year of a three year project funded by SAGIT Sites located at Waikerie and Loxton in the SA Mallee Two trials located at each site: heavy and a light soil Nine break crop options tested side by side Agronomy optimised for each treatment About the trial

  9. 9. Biomass production for each crop was relatively consistent between sites All crop options except for albus lupin and kabuli chickpea averaged greater than 2 t/ha of biomass Field pea averaged 3.1 t/ha with no less than 2.7 t/ha Vetch dry matter production suffered greatest on the limestone flat Lupin biomass was higher than average on the deep sand but was still less than vetch and field pea Biomass – key points

  12. 12. Earlier maturing crops such as lentils, field pea, vetch and faba bean produced the best grain yields in a season with several heat events during October Lentils had the most consistent and highest average grain yields (0.73 t/ha) Field pea had the highest grain yield at any site (1.2 t/ha Waikerie sand) but yields were inconsistent due to frost on lower lying flats Lupins and chickpeas averaged 0.5 t/ha or less in 2015 Grain yield – key points
