wheat yield gain

Catalogue: Ground Cover
In the central wheatbelt researchers, agronomists and growers are seeing crop yield responses of 0.5 to 1 tonne per hectare where CTF is being used in conjunction with deep-ripping on compacted sands... Department of Agriculture and Food, WA (DAFWA) officers Dr Paul Blackwell and Bindi Isbister say global research shows that where CTF is being used to help protect investments in deep-ripping or other mechanical amelioration tactics for compacted soils (such as inversion ploughing, rotary spading, delving and deep working seeding points) the benefits can last for many years... DAFWA-Liebe Group trials at Buntine are also finding wheat yield gains of up to 15 to 42 per cent - depending on the season - are possible from using CTF with deep-ripping to a depth of 35 to 40 centimetres on compacted sands in years with below-average rainfall...

"Without CTF, the benefits of these tillage systems to alleviate compaction might only last for a season or two," Dr Blackwell says...

His trials at Dalwallinu, Merredin and Mullewa in 2012 and 2013 demonstrated that some wheat varieties could establish well when sown to a depth of 70-100mm... But establishment across all sites was reduced by between 17 and 61 per cent with deep sowing, compared to establishment from a sowing depth of 50mm (especially in varieties with short coleoptiles and on loamy soil)... At the North Miling site, establishment was similar for shallow (28mm) and 'normal' (52mm) sowing depths, but deep sowing to a depth of 119mm reduced establishment by between 22 and 45 per cent for a range of wheat varieties...
