Trial aimed to investigate the impact that different stubble treatments imposed towards the end of the fallow have on the establishment and yield of canola.
• During 2013, in canola crops sown on time that achieved target plant populations, it appears that late burning and/or cultivation of previous crop stubbles improved yield. • The cost of burning stubble needs to be considered both in terms of dollar labour cost and lost nutrients. Potential impact on fallow efficiencies following the canola crop need to be better understood. Burning stubbles may have a fit in paddocks where windrows are being burnt for grass seed control or stubbles are too heavy for seeders to get through. • The cost of cultivation needs to account for both cost of the operation as well as the risk soil erosion, and the possibility of producing drier seedbed conditions at sowing time. • CWFS proposes to do further trials in the next two years. Remember this report represents only one year (2013) of data from trials at Rankins Springs, Wirrinya and Tullamore.
