Inter Row Benefits Across the Rotation

Author: Dr Matthew McCallum

Three years of research on inter row sowing, in South Australia, supported by SAGIT, has identified that the system offers some clear agronomic and economic advantages. The trials were based at Kimba (Upper Eyre Peninsula), Hart (Mid North), Waikerie (Mallee) and Sandilands (central Yorke Peninsula). In 2006, a site was also located at Karkoo (Lower Eyre Penisula). A series of experiments was established at these sites to investigate: • Canola plant establishment and growth in heavy cereal stubble • Efficacy of soil applied herbicides • Lentil harvestability • Wheat on wheat yield performance Crops were compared inter row to in row with standing stubble, and at Sandilands three stubble treatments were used – standing, burnt and slashed. The economic benefit for significantly different treatments were calculated based on $220/t for wheat and $500/t for canola. Download the article to read more
