Take home messagesAcid-tolerant strains of Group F rhizobia increased the nodulation of faba beans on acidic soils (pH<5.0 CaCl2) with low background rhizobia at Chatsworth and Rokewood, Victoria, but optimal nodulation rates were not achieved.After a late break, with adequate chemical fungal disease control, PBA Samira faba bean grain yields at Ta...

Take home messages • Yield increases are necessary to keep cost of production for Australian growers competitive in international markets. • Australian growers need to double the recent rate of yield gain (25kg/ha/year) to offset the recent effects of climate change (-24 kg/ha/year). • Yield increases are rarely the result of a single practice or t...

• This study aimed to provide an overview of currently available plant-based meat substitutes available on Australian supermarket shelves, nutrition composition compared to animal products of comparable culinary use (burgers, sausages and mince) and changes in the make-up of the category from 2015 data. • Product numbers increased 429% in four year...

• All grain legume (pulse) crop residues generally have higher concentrations of nitrogen (N) and lower C to nitrogen ratio than cereal crops. • The rate and timing of availability of N from pulse stubble to the following crops is determined by stubble decomposition rate and N immobilisation (tie-up) by soil micro-organisms. • N mineralisation/tie-...

Take home messages • Preserving or enhancing soil organic matter stocks is critical to sustainable agriculture, due to its key role in soil health, plant productivity and building resilience. Stubble return with strategic nutrient inputs (‘integrated stubblenutrient management’) has been proposed as a measure to build soil organic matter in croppe...

Take home messages • The GRDC national phenology initiative has been established to better predict flowering time of wheat and barley across the major cropping regions of Australia. • A total of 64 wheat and 32 barley genotypes, selected for their diverse phenology, are being genotyped and phenotyped under different controlled conditions to paramet...

Results from 2019 indicate that oats can achieve similar or higher biomass than wheat (Scepter) and barley (Compass). Growers have access to oat cultivars with similar development speeds to Compass barley and Scepter wheat and are likely to flower within a similar frost risk window. Early May sowing of oats in 2019 achieved higher total biomass and...

Take home messages • Crop establishment among commercial crops is variable and improvements can be made in many cases. • Improving establishment may lead to saving in seed costs. • Establishment of canola and lentil is influenced by different factors. • While some factors are outside the control of growers, there are a number of simple changes tha...
-
Take home messages • Season has the greatest impact on productivity with yields almost four times greater in a high rainfall year (decile 8-10), than in a low rainfall season (decile 2-4). • The highest, and least variable grain yields were achieved on sandy loam – loam soil types, with up to 60% lower productivity, and high yield variability obtai...
-
Take home messages • Consistent first-year yield responses to deep ripping have been measured on Victorian Mallee sandy soils, with yield benefits commonly 0.5 to 1.0 t/ha in the first season following deep ripping. • Yield responses to deep ripping have not been improved through additional inputs of fertiliser or organic matter (OM) on sandy soils...
