The scarcity of water emphasizes the need of using irrigation water judiciously. The advance irrigation systems like drip and sprinkler irrigation etc. apply water accordingly. If one wants to apply water precisely, the criteria based on real time soil moisture can be used through which precision in irrigation can be achieved. Therefore, an attempt was made to design and develop the real time soil moisture based automatic irrigation system with GSM. However, study conducted by various scientists on performance evaluation of automatic irrigation system found that the depth of placement of sensor considerably affect the irrigation efficiencies. A very few scientists have worked on the appropriate depth of placement of soil moisture sensors. Therefore, the performance evaluation of an automatic irrigation system under three different depths i.e., 7.5 cm, 10 cm and 12.5 cm were carried out. The system was tested on cabbage crop. The biometric observation revealed that the crop under 7.5 cm depth of the sensor was superior over the other two depths with maximum water use efficiency. Further, it is revealed that the use of an automatic irrigation system with sensor placement at 7.5 cm depth was working efficiently and effectively along with saving water.
