Abstract:

Many areas of agricultural fields are effectively over or under irrigated due to spatial variability in water infiltration and runoff of rainfall and irrigation, crop water use and irrigation depth. Under-irrigated areas are subject to water stress, resulting in production loss, while over-irrigated areas suffer from plant disease and nutrient leaching. This research presents the design of microcontroller based soil moisture sensor was developed at College of agricultural Engineering, Bapatla. It was developed for adaption of Indian farmers to facilitate high water use efficiency by replacing hardware components with software functions which allows farmers to apply the right amount of water at the right time. The developed sensor 8051 microcontroller is designed using keil µvision 3 software for maximum of four sensors present in each field and controls the water supply in the field to be irrigated using solenoid valve. The sensor present in each field stops the pump automatically through microcontroller when the field reached to its field capacity and the motor will be switched on automatically when soil moisture reaches 70% of field capacity. Microcontrollers then supply water to that particular field for which water requires, till the sensors are deactivated again. The experimental field with an area of 1330 sq m for sweet corn crop was selected for performance evaluation with three sub plots i.e., flood method, single row and paired row drip method. Overall yield response and water use efficiency for sweet corn crop is highest in single row drip method with 7.93 t ha-1 and 23.88 kg/ha-mm respectively. Water applied in drip irrigation system using soil moisture sensor was found to be 332 mm instead of 520 mm in flood method for sweet corn and 36% water saving was observed. The total cost of the microcontroller based soil moisture sensor was Rs. 3755 as compared to the Rs. 1 lakh worth commercial available automated system.
