Sensor height and orientation impacted measurements up to 45 days after planting but not once was the canopy was fully developed. The most accurate yield predictions were obtained 49 DAP when sorghum was 0.76 m tall. The INSEY expressed as plant growth per day (INSEYDAP) best correlated with yield. The results of the study show that crop sensors can be used to accurately predict forage sorghum yield, but timing of scanning and scanning height and orientation need to be standardized to obtain algorithms that can cover a larger region.
