Soil Moisture Controlled Surface Drip Irrigation on Sandy Soils
K. Dhana Lakshmi, M. Narayanan
Abstract: The belowground drip irrigation (SDI) is being adopted in areas to conserve water whereas maintaining for economical production of crops. These systems haven't been evaluated on sandy soils common to American state. AN SDI system was put in on a well?drained sandy soil for sweet corn production in American state. The SDI conduit was buried underneath every (76?cm spacing)at either 2 depths of twenty three or thirty three cm below the bottom surface to lead to 2 experimental treatments. in addition ;the two ways of irrigation planning were obligatory on the SDI treatments. One planning treatment was the initiation and termination of irrigation supported soil wet measured by time domain reflectometry (TDR) probes put in five cm on top of the drip line. And also the different planning treatment was a daily irrigation event at rates per typical apply within the region. Mechanical device irrigation scheduled kind of of like farmer practices within the region and non?irrigated management treatments were conjointly established. The soil wet mostly irrigation planning regime resulted in high frequency short period (30?min) irrigation events to satisfy crop water desires. The 23?cm deep soil moisture?based treatment resulted in similar yields and similar water use in 2002 and reduced water use Martina's with similar yields compared to mechanical device irrigation in 2003. this means that 23?cm deep Sides possible for sweet corn production underneath these conditions. the employment of water was achieved with soil wet based mostly set points of 100 percent to twelve-tone music by volume (on?off). The 33?cm depth. like farmer practices within the region resulted in high frequency short period (30?min) irrigevents to satisfy crop water desires.
