Matching the supply of nitrogen (N) with crop demand is critical to optimising nutrient use and profitability of grain production. Defining the ability of a soil to deliver available N both prior to and within the grain growing season is required to help optimise N fertiliser application rates. • The amount of N delivered to crops from soil will be...

Inoculation of faba bean, lentil and field pea with rhizobia (Rhizobium leguminosarum bv. viciae) is critical on acid soils. Nodulation is improved by increased application rate of inoculation products. •The lower limit of pH(Ca) for reliable nodulation with the commercial strains of faba bean and field pea rhizobia is 5.0. • Liming to increase so...

In 2017, low yielding, unprofitable canola crops grew near profitable crops where strict attention to the system and timely agronomic management occurred. • Matching the phenology of a variety with sowing date was paramount for grain yield, largely avoiding major frost damage. At all sites, yield was reduced when flowering started before August. • ...

The yield gap, or the difference between actual and potential yield in wheat, was 1.1, 1.2 and 1.3t/ha across the Northern, Southern and Western GRDC regions of the Australian grain belt, respectively in 2015 and 2016. • The cause of this yield gap is variable. No one factor (nitrogen (N), disease, weeds or rainfall) is a cause of the yield gap — i...

Australian grain growers lead the world in their ability to produce crops in climatically restrictive environments. • An efficient method to quantify plant available water will add value to current precision agriculture (PA) techniques by allowing growers to match production inputs and expectations with reality. • The Internet Of Things (IOT) in ag...

Riverine Plains Inc conducts a range of research activities, with investment from GRDC and other partners to provide local information to members. • Large farm scale trials provide grower-relevant information. • Decisions about stubble management require consideration of the whole system across a range of seasonal conditions. • Stubble management c...
