Irrigation Scheduling Using Low Cost Plant Leaf Temperature Sensor Based Water Application System for Increasing Water Productivity of Fruit Crop

A sensor was designed and developed to measure the plant leaf temperature and ambient temperature in the kinnow orchard. The developed sensor circuit was then interfaced with the drip irrigation head works for irrigation automation. The microcontroller was programmed on based on leaf-air temperature differential values measured by the developed temperature sensors. The developed system was tested in the field for Kinnow (Citrus reticulata Blanco) crop for its performance. The system maintained the soil moisture content nearer to the field capacity as per the leaf-air temperature differential conditions and used 8 % less water per month per plant compared to the using drip irrigation system. The developed automated system was of low cost which can be afforded by the small and marginal farmers and also easy to install.
