A field experiment was conducted with two different potato (Solanum tuberosum) varieties (i.e. Ashoka and Jyoti) at “C” block farm of the Bidhan Chandra Krishi Viswavidyalaya at Kalyani during the period of November-March (2009-2010) to study the performance of different potato varieties under three different irrigation levels (I1, I2 and I3) with 30 mm irrigation depth. The total experiment was conducted under two treatments (D1 and D2) during the above period. The soil was sandy-loam with medium land situation. The plot size was 4.5 m × 3.7 m. The maximum yield recorded under D1 was 50.56 t ha-1 and the maximum yield under D2 was 63.65 t ha-1. Soil moisture content in the soil profile varied widely in the two varieties. Irrespective of variety and irrigation level, the highest average seasonal evapotranspiration (SET) (187.71 mm) was recorded under 2nd planting date (D2: 29.11.09) and it was around 36.32 mm lower when the crop was planted 9 days earlier. Among two cultivars, the total water productivity (TWP) of Ashoka variety was at the highest level (40.82 kg m-3) and it declined by about 6% under Jyoti variety.
