In between rains or irrigations, crops must fulfill their water needs using water reserves in the soil.
Under optimal conditions the soil, water, nutrients and plant roots are all in one location and in sufficient quantities. The umbrella-type potato cropping system currently used reduces the water volume retained in the soil and accessible to crops.
Modifying the cropping system design is an effective way to improve potato crop water-use efficiency and, thereby, lessen the risk of crops experiencing water stress. Furthermore, better water utilization means better nitrogen utilization!
From 2019 to 2022

This three-year project looked at optimal ways to use a mix of flowering plants against caterpillar pests of crucifers.
The aim of this project was to study the relationship between thermal imaging data collected by drone and agrometerological indicators of water stress in potato crops.
