DAFWA wheat agronomy project manager Christine Zaicou-Kunesch with Richard Quinlan, of Planfarm, and Woongoondy grower Gerard Rowe at the GRDC-funded RCSN early sowing wheat trial site at Yuna... Ms Shackley said the trials aimed to determine the grain yield and quality responses of a range of slow, mid and fast-maturing winter and spring wheat varieties when sown in mid-April, compared with more conventional WA wheatbelt sowing times of early and late May... "Most varieties trialled had the highest yields when sown in early May, or the yields were not significantly different between mid-April and early May sowings," Ms Shackley said...

Modern farming systems enjoy a greater range of tools to aid in decision making during the growing season... There are a range of products and services to help with in-season decision making: simple historic rainfall and temperature deciles, such as Rainmain or CliMate; seasonal forecasting, such as SOI, IOD and ENSO; short term weather forecasts (a large range of websites and apps available); yield prediction tools and newsletters, such as Yield Prophet, Hart Beat, The Break; and soil moisture probes... Further to the products, growers also have the ability to make variable rate input decisions based on paddock spatial variation through crop sensors mounted on tractors, satellite photos or other images collected from planes or UAVs and drones...

Paul Telfer: The most adverse effects of heat stress on yield have been found to occur during flowering rather than grain fill... The wheat plant is most sensitive to heat stress during flowering and grain filling, and 'heat-stress events' often coincide with drought stress and frost events... In the short term, the data collected has highlighted that current best practice in terms of sowing time and appropriately matching it to crop maturity are the best ways to minimise the effects of heat stress on crop production...
