This is particularly important as cotton is vulnerable to climatic conditions, which creates a narrow harvest window.
HAs are typically prescribed when a high percentage count of Open Bolls indicates that the crop is close to harvest. However, as OBPC increases, there is also a corresponding drop in NDVI values due to plant aging.
Using its own vegetation index, the Augmenta System exploits this correlation in order to carry out Augmenta HA VRA operations. Uniquely camera-based, the Augmenta System uses computer vision techniques and dynamic algorithms to generate the AUG-Index which detects plant senescence and the need for HA. An on-the-fly prescription map is created which controls an actuated sprayer and automatically applies appropriate amounts of HA Defoliant in real time and in a single pass.
By intelligently applying a recommended dose of HA, waste and input cost reductions are possible. At the same time, greater yield and higher economic returns can be realized.
