Hydraulic Stress of a Cucumber Crop

The study took place over a 14 day period. During this time themographic images from the crop where taken to determine if it was suffering from hydraulic stress or not. The location of the study was Ecuador and I took this location because the economy of this country relies heavily on agriculture. Many problems were observed and during the 14 day period hydraulic stress was the cause of damage to many of the cucumber plants. The health of some of them was seriously deteriorated and this resulted in an economic loss for the owner of the plantation.

Using a Flir Thermographic camera I captured key points of the plantation which I divided into 4 sections. If the temperature of a given plant had a +5 or -5 degree celcius difference with atmospheric temperature then I would take a closer look as this meant the plant was suffering from hydraulic stress. One of the mayor problems in Ecuador in general is that during rainy season owners of plantations do not apply an irrigation schedule because it used to rain a lot but climate change has taken its toll with many dry days during this raining season.At the end I created an irrigation schedule to improve the performance of the crop and avoid hydraulic stress on the plants.

Instrument Error Graph

A small error was detected due to the time of the day the pictures were taken. This is the correction that was applied.
