The reality of data science.

@merindie1 It is a bit harder to pinpoint long term wheat production in Tassie. We could create the product if there is enough demand for it.

@ralawes Can not find subscription for Tasmania, not sure how you can claim every paddock if nothing for Tasmania. Am I missing something??? Or #falseclaims

@bentags Hi Ben, it provides the output as an API, which is designed for Ag tech companies or others to build it into their products.

@ralawes Not sure if I'm being simple Roger, but how do we actually access/use it?

@SamsAgronomy @KSUWheat @LucasAHaag @KansasWheat @KStateAgron @PedreiraBC @KsWheatAlliance @HortonSeedman21 @KelseyFAndersen Grain number swamps grain weight as the driver of yield. Lots of studies show this.

@KSUWheat @LucasAHaag @KansasWheat @KStateAgron @PedreiraBC @KsWheatAlliance @HortonSeedman21 @KelseyFAndersen Is there a known correlation between seed size and yield? I trialled this some years ago. And I found no statistical difference in yield. I know this is a difficult trial with so many other factors from TOS to harvest that can and do go wrong, however still need the evidence.

Know your #wheat seed size! In this sample of 40 current hard winter wheat varieties, seed size ranged from 10,499 to 19,691 seeds/lb. Although half of the varieties fell in the 13,300-15,000 seeds/lb categories, the other half was either much larger or smaller than that.

This @CSIRO #Graincast forecast of the national wheat yield harvest is based on data up to 1 Sept 2021. The median forecast is 2.09 t/ha with a 97% chance of exceeding the 15 year average of 1.79 t/ha. For more detail and state by state forecasts visit research.csiro.au/graincast/whea…

@mdfowler100 Hi Mark, yes a system has been created to model temperature with a topo map.

These stations (where we farm) are broadly in the same area but show the (big) difference between hillsides and valleys. #allcold🥶 Has anyone modelled temp change / change in altitude (height above sea level)? Or are there just too many other variables (topo, soil-type, etc)?

Our @CSIRO #Graincast forecast of the national wheat harvest is based on data up to 1 July 2021. The median forecast is for 2.27 t/ha with a 95% chance of exceeding the 15 year average of 1.79 t/ha. For more details and state by state forecasts see research.csiro.au/graincast/whea…

It's the 20th of April, so time to start tweeting the #CSIRO #Graincast wheat yield forecasts for 2021! We've added a few bells and whistles for this season: maps of soil water, water-limited yield forecast (see map) and their uncertainty as well as state specific forecasts.
