low plant density

Catalogue: GRDC Media
Project leader Mark Seymour, of DAFWA, said last year's canola plant density trials showed that canola establishment can fluctuate very widely - from 30 to 80 per cent - with changes in soil moisture, soil temperature and variety... Mark said a density of 20-30 plants/m 2 was adequate for most varieties at most trial sites to achieve good establishment, ensure robust weed competition and produce yields of about 0.8-2 tonnes/ha... Mark said the trials showed optimal plant density for canola in low and medium rainfall zones tended to vary with variety and herbicide tolerance production system...

Optimum canola densities tested for lower-rainfall zones.. Mark Seymour, leader of the GRDC-DAFWA tactical break crop agronomy project in WA, at a trial site examining canola plant density at Salmon Gums in 2013... Mr Seymour says, overall, the trials highlighted that economic optimum plant density for canola differs for each variety and herbicide-tolerance system and adjustments need to be made according to the rainfall zone...

Northern chickpea growers are advised to sow at optimal seeding rates, irrespective of sowing date, to ensure early canopy closure and minimise the risk of viruses... Dr Andrew Verrell, NSW Department of Primary Industries (NSW DPI) research agronomist says recent research supported by the Grains Research and Development Corporation (GRDC) shows growers should sow chickpeas at optimal seeding rates - irrespective of sowing date... Dr Verrell says there are more than 14 species of virus that naturally infect chickpeas and are spread by airborne insects, particularly aphids...

Flexibility guides canopy management.. Canopy management trials near Wagin, Western Australia, indicate medium plant density (120 plants per square metre) and tactical nitrogen applications during the growing season can pay off with higher yields - especially in years with a drier-than-average finish... Mr Gray says timing of split nitrogen applications did not affect wheat yields in the Wagin 2012 trials...

Results show a 1kg/ha seeding rate increase provides positive returns.. When growers are expecting low establishment due to sandy or heavy soils, or a dry start to the season, increasing the seeding rate by around 1kg/ha can make a significant difference to yield," Mr Mock says... Herbicides evaluated in the trials for carryover effects on canola were 2,4-D ester, 2,4-D amine and Intervix ...
