Pakistan faces surface water and groundwater shortage which are the main reason for assessing more appropriate method of
irrigation water use. Subsurface drip irrigation plays an important role to conserves irrigation water and enhances crop yields
by reducing surface water evaporation in Pakistan. Two years (2019-20) trials were carried out at “Water Management
Research Center” (WMRC), Mansoor Malangi road Faisalabad, under randomized complete block design (RCBD). Maize
(Zea mays L.) hybrid variety “YH-1898” was selected for this experiment with sandy loam soil. Sub-surface drip laterals were
buried manually at different depths of 0.15, 0.25 and 0.35 m. The results of subsurface drip irrigation for crop water
productivity and maize grains yield were compared with surface drip and gravity irrigation methods (furrow-bed and furrowridge). The outcomes showed that maximum grain yield (8753 and 8860 kg/ha) was achieved in both the seasons in 2019 and
2020, respectively under sub-surface drip irrigation installed at a depth of 0.15 m. Similarly, the results of water productivity
also revealed that the highest water productivity (2.074 and 2.085 kg/cm3
) was concluded both the years in 2019-20,
respectively under subsurface drip irrigation installed at a depth of 0.15 m. It is concluded that maximum grain yield and water
productivity can be accomplished by the installation of sub-surface drip laterals at 0.15 m depth for maize crop in a semi-arid
region of Pakistan.
