Summary

This proposal continues research initiated in RIRDC project DAN 248A – Understanding, quantifying and managing spatial variability of rice growth and yield. It comprises two components;
1. The major component in this project relates to precision agriculture and researching approaches to aid the identification and management of the spatial variability in rice growth and yield within the field,
2. The second and minor component involves maintaining the NIR instruments and their calibrations for the NIR Tissue Test service and updating the associated nitrogen topdressing recommendations.

Objective Summary

The project objectives are to:
1. Identify and understand factors contributing to in-field spatial variability in rice yield,
2. Identify and evaluate methods by which ricegrowers can manage in-field spatial variability in yield to increase production, profitability and water productivity.
3. Maintain the NIR calibrations and instruments for the rice NIR Tissue Testing Service and update the associated PI nitrogen topdressing recommendations.
