英文摘要	Soil salinity is a major soil degradation problem that limits agricultural production. The cut-soiler constructed preferential shallow subsurface drainage (PSSD) method is a promising salinity management technology for small-scale application and adoption in drylands. This study assessed the effectiveness of rice residue-filled PSSD in managing soil salinity and its effect on the physiology and yield of pearl millet. The cut-soiler simulated drains were constructed manually in semi-controlled lysimeter. A double replicated, split-spilt plot experiment, comprising with and without cut-soiler drainage (main-plot), two soil types (sub-plot) and three irrigation water salinity (4, 8, 12 dS m(-1)) (sub-sub plot) were conducted during 2019-2020. The cut-soiler PSSD reduced similar to 60% soil salinity after 2 years. The PSSD reduced soil salinity by 23.28 and 41.46% in April 2019 and April 2020 (before pearl millet sowing). This reduction was 32.24 and 46.23% in October 2019 and 2020 (at harvest). Cut-soiler drainage (PSSD) areas recorded lower soil moisture (%) indicated greater outflow of water and salinity. The salinity Inhibition efficiency increased upto 2 years of construction and then decline. The pearl millet grain and biological yields were improved by 23.54 and 12.64%, respectively and a positive effect on plant water relations and physiology was observed. The cut-soiler PSSD was found to enhance salt removal and reduce salt accumulation under saline water irrigation. These drains can be constructed in a single farm operation at individual farm levels. Therefore, it could be a potential alternative for soil salinity management in semi arid regions irrigated with saline groundwater.
