This study determines the effect of N fertilizer placement, N fertiliser rate and N application timing on the competitive ability of wheat (Triticum aestivum L.) in dryland no-tillage cropping system in the Western Australian grainbelt.

To (i) ground truth through statistical analysis of small plot trials current practices of leading farmers in regards to the use of Variable Rate Technology (VRT), predictive yield modelling and nutrition modelling in improving water use efficiency and hence profitability; (ii) address the hypothesis that greater return on investment can be achieved through targeted nutrition applications according to variety, production zone, plant available water (PAW) and seasonal conditions; (iii) assist in the generation of data to extend the process of using soil moisture probe data in conjunction with Yield Prophet (YP) simulations to assist with production decisions for different soil zones (with differing PAWC), with particular focus on top-up nitrogen.
