Effects on growth and yields of sweet corn using internet of things (IoT) based smart drip irrigation and ETc based drip irrigation systems Singh C. D.*, Kumar Vinod S.

Online Published on 10 January, 2024. Abstract Growth and yields of sweet corn using an IoT-based and an ET-based drip irrigation system is evaluated. Growth characteristics (plant height, yield, and water productivity) were compared for both approaches. For IoT based soil moisture method, two irrigation regimes were used: 43.5 per cent and 34.8 per cent of volumetric soil moisture. For ET-based method, only one i.e. crop evapotranspiration (ETc100 per cent). It has been found that the IoT-SM43.5 per cent produce higher yields of 12.05% and water savings by 11% compared to the ETc100 per cent-based irrigation method. The results indicate that best irrigation scheduling strategy is determined for commercial production: keeping the soil water content near field capacity which result a better fresh yield and less dry matter.
