The article discusses how raingun sprinkler systems, made locally, were tested to see how well they work for irrigation. The researchers wanted to see if these systems were effective and could help manage salinity in plants. They set up tests to see how these systems performed in real-life conditions. The results showed that the locally manufactured raingun sprinkler systems worked well for irrigating the plants and helped manage salinity in the crop root zones. This means that these systems could be a useful tool for farmers to efficiently water their crops and deal with salinity issues in the soil.
