Project Summary:
Airborne multispectral digital imaging is a cost effective means of acquiring metre resolution imagery of agricultural fields for assessing the variability of developing crops. Variability in crop emergence and in the established canopy of young crops is in most cases linked to variability in utilisation of nutrients, and ultimately crop yield.

Models used to estimate crop yield potential and nutrient requirements often fail because they do not account for "transient" causes of variability due to, for example pests, competition with weeds and unexpected seasonal changes. Timely data concerning crop variability is potentially useful for maintaining the veracity of model predictions throughout the season and for extending these models into predicting the spatial variability of yield within a given field. This project will examine the usefulness of airborne multispectral imaging as a support tool for rice crop management and for enhancing the predictive utility of existing crop models
