Preliminary results from CSIRO research in Narrabri have shown that genetically modified insect-resistant cotton may also be more water efficient.*
Two years of field experiments by CSIRO Plant Industry’s Mr Dirk Richards and Mr Stephen Yeates, show that under normal full irrigation, Bollgard® II cotton used ten per cent less water than an equivalent conventional variety and had higher yields.
Bollgard® II makes up most of the Australian cotton crop and has reduced pesticide use by up to 80 per cent.
Research is now optimising agronomic management of Bollgard® II as it tends to produce bolls earlier than conventional cotton because insect damage does not delay early crop growth.
Bollgard® II and conventional cotton extract soil water at a similar rate, but Bollgard® II has a more compact growing season so uses less water overall for the same or higher yields.
