The 2020 South Australian Crop Sowing Guide is now available to support growers with their variety choices ahead of next year's sowing programs.
The publication is available on the Grains Research and Development Corporation (GRDC) website at https://grdc.com.au/2020-south-australian-crop-sowing-guide and copies will also be arriving soon in growers' letter boxes.
The SA Crop Sowing Guide has been published by the GRDC in partnership with the South Australian Research and Development Institute (SARDI), the research division of Primary Industries and Regions SA (PIRSA), and the South Australian Grain Industry Trust (SAGIT).
GRDC's National Variety Trials (NVT) Regional Manager - South, Rob Wheeler, says the publication provides the most up-to-date information on disease resistance ratings and variety performance at a time when growers are planning their seed requirements for 2020.
"The SA Crop Sowing Guide outlines information on current varieties of the major winter crops grown in SA," Mr Wheeler says.
"The publication prompts growers to ask whether they are growing the best variety for their location, environment and farming system.
"Growers are encouraged to use the summary as a guide for discussion with their consultants, advisers and marketing agents."
Mr Wheeler says the majority of grain yield and quality data provided in the summary is sourced from the GRDC NVT program of comparative crop variety testing, with data from some breeding trials added to the information available.
"Results from the NVT program are also used by pathologists to determine disease resistance ratings presented in the SA Crop Sowing Guide. It is important that growers check the disease resistance ratings each year for any changes from the previous season," he says.
"Overall, the summary brings together NVT data from the previous five seasons, long term multi-environment trial yield predictions, disease ratings, quality data and agronomic information."
The latest 2019 NVT data will also be available early in 2020 via the NVT Online website at www.nvtonline.com.au.
