Field experiment was conducted during 2017 to study the effect of deficit irrigation practices through drip system and soil moisture distribution in maize. Creation of soil moisture gradient is indispensable to explore the beneficial effects of partial root zone drying (PRD) irrigation and it could be possible only through alternate deficit irrigation (ADI) practice in paired row system of drip layout, which is commonly practiced in India. In the present study, PRD and deficit irrigation (DI) concepts (creation of soil moisture gradient) were implemented through alternate deficit irrigation (ADI) at two levels of irrigation having full and partial application at 60, 80 per cent PE as well as ETc based levels using drip system, comprised of seven irrigation levels. The results of the experiment showed that, irrespective of the levels of irrigation, SMC was low at 30 cm distance from the plant both across as well as along the laterals. The reduction in the SMC also recorded corresponding to the decreased level of water application (at all the locations). Further, it was observed that the alternate deficit irrigation (ADI) concept exerted with uneven distribution of moisture in the levels of both PE based irrigation application as well as ETc based. Among the ADI treatments, ADI as 80 and 60 per cent PE had less uneven distribution than ADI as 80 and 60 per cent ETc based irrigation.
