A field experiment was conducted for two consecutive years (1995–96 and 1996–97) on light textured (Typic Ustocrept) soils at Central Potato Research Station. Modipuram, Meerut (U.P.) to develop a low cost input technology for producing the seed size tubers (10–40 g), involving irrigation schedulings through modern methods of irrigation and lifting dates. Irrigation schedulings through drip and sprinkler methods produced significantly higher aggregate yield and number of tubers than conventional furrow method of irrigation. It also increased 10–40 g size tubers, which could be used. as seed material for planting 20–25% more area. These modern methods of irrigation also improved plant height and number of stems/plant. Crop harvested at 70 days after planting produced significantly higher number of 10–40 g size tubers as compared to 80 days. In case of large size tubers (above 40 g) the reverse trend was noticed.
