Abstract


An investigation on drainage requirement of saline soils with an acute outlet problem such as in case of saucer type of basin of Agricultural Research Station, Gangavati, was investigated during 1983-93. Results of the experiment in terms of soil salinity, chloride salinity, carbonates and bicarbonates removal and de-sodication pattern revealed that for short term gains, a vertical drain with lateral (15 m length) was better than vertical drains without lateral. However, for long term gains, vertical drains without lateral was as effective as with lateral. The cost comparison favoured a vertical drain without lateral (Rs. 34605.00 per ha) than both the vertical drain with lateral (Rs. 68033.00 per ha) and the conventional horizontal system (Rs. 43328.00 per ha) for 15 m drain spacing.
