Abstract
An electronic tensiometcr has been developed which can automatically control all types of high frequency irrigation systems such as sprinkler irrigation etc. The user can set two levels of tensions in the instrument. Upper limit, at which irrigation is to be started and lower limit at which irrigation is to be stopped. When fitted to any high frequency irrigation system, the tensiometcr will monitor the prevailing soil moisture tension and when it reaches the upper limit of set tension, it will activate either a solenoid valve or an electric pump thereby starting irrigation. Once irrigation is started, the instrument will again monitor the soil moisture tension and when it reaches the set level of lower limit, it will stop irrigation. The auto irrigation system was installed along with a drip irrigation system in a coconut garden and performed well for two irrigation seasons.
