In a study comparing different drip irrigation systems for growing tomatoes, researchers aimed to find the most efficient method to use water while maximizing crop output. They tested four types of automated systems against a conventional one in the Kharif seasons of 2018 and 2019. The soil moisture sensor-based system proved to be the best, yielding 99 tons per hectare and using water 2.52 tons per hectare cm more efficiently than the other methods. This means that scheduling irrigation based on soil moisture levels is the most effective way to grow tomatoes using drip irrigation.
