The project will look in detail into potential limitations and provide recommendations on how they can be managed.
Focus Paddock 1. DS Bennett wheat: Nitrogen application- To ascertain the impact of prior year nitrogen application on the yield of the current years crop.
Focus Paddock 2. T4510 Canola: Lime Incorporation- To ascertain the impact of ameliorating subsurface acidity by incorporation of lime.
Focus Paddock 3. Raptor Canola, Nitrogen Rates- To Determine the optimum rate of Nitrogen for canola.
Focus Paddock 1. Early lodging resulted in yield loss in the DS Bennett wheat. This was caused by several factors, including: very early sowing of a weak strawed variety, high levels of soil and applied nitrogen and grazing that had to be stopped early due to animal health issues.
Focus Paddock 2. Soil testing in 5cm increments identified extremely acid areas (pH CaCl2 of 3.90 -4.6) between 5 and 15cm.
The lime was incorporated to target the subsurface acidity. Areas incorporated had an increase in yield compared to those that weren’t. Incorporation is a long term investment.
Focus Paddock 3. With the current price of urea, consider the amount and timing of nitrogen (N) in canola to optimise profitability and yield. The Green Area Index (GAI) can be used to quantify the size of the canopy and may be a better way of being more accurate
with rates and timings of N application.
The Hyper Yielding Focus paddocks provide an opportunity for farmers and advisors to evaluate Hyper Yielding Research results in a paddock situation.
