Short Summary

This study evaluated the performance of electrical resistance and capacitance soil moisture sensors for precision irrigation in bottle gourd, finding that capacitance sensors provided more consistent measurements and significantly improved crop yield by 21% and irrigation water use efficiency by 51% compared to manual irrigation.

Objective

• To evaluate the performance of Electrical Resistance and Capacitance based soil moisture sensors for precision irrigation scheduling in a bottle gourd crop.

Study Configuration

• Spatial Scale: Field experiment on a bottle gourd crop, with sensors installed at two soil depths (0-0.15 m, 0.15-0.30 m).
• Temporal Scale: Duration of bottle gourd cultivation (crop growing season).

Methodology and Data

• Models used: Not applicable; experimental comparison of sensor types.
• Data sources: Electrical Resistance (ER) soil moisture sensors, Capacitance-based soil moisture sensors, gravimetric soil moisture measurements, and bottle gourd yield matrices. Performance metrics included Mean Square Error (MSE) and Root Mean Squared Error (RMSE).

Main Results

• Capacitance sensors provided more consistent and responsive measurements across varying soil moisture levels.
• Electrical Resistance (ER) sensors showed greater variability under field conditions.
• Capacitance-based soil moisture sensor irrigation system improved bottle gourd yield by 21% compared to existing manual irrigation practice.
• Capacitance-based soil moisture sensor irrigation system improved irrigation water use efficiency by 51% compared to existing manual irrigation practice.

Contributions

• Provides a comparative evaluation of different soil moisture sensor types (Electrical Resistance vs. Capacitance) specifically for precision irrigation scheduling in vegetable crops (bottle gourd).
• Quantifies the significant benefits of capacitance-based precision irrigation in terms of increased crop yield and improved irrigation water use efficiency under field conditions.
• Offers a practical recommendation for adopting capacitance-based soil moisture sensors for efficient water management and enhanced crop productivity.
