Plant-based indicators of water status, such as midday stem potential (Ψstem) and leaf stomatal conductance (gs), are used to optimise irrigation scheduling in horticultural crops because they integrate the effect soil climatic conditions internal physiological constraints. The use these relies on experimentally acquired thresholds that relate value indicator negative ...

Estimating crop yield using remote sensing techniques has proven to be successful. However, sugarcane possesses unique characteristics; such as, a multi-year cropping cycle and plant height-limiting for midseason fertilizer application timing. Our study objective was to determine if sugarcane yield potential could be estimated using an in-season estimation of normalized difference vegetative in...
