Abstract:

The field experiment was conducted during the rabi season of 2005-2006 in Pusa Farm of Rajendra Agricultural University, Bihar in split plot design with sixteen treatment combinations consisting of four levels of irrigation and four levels of potash. Irrigation treatments were given after a common irrigation at 15 days after planting and 6 cm irrigation water was applied in each irrigations. Potato variety "Rajendra ALU- 3" was taken for present investigation. Total water requirement of I3 (1.0 IW/CPE ratio) and I4 (1.2IW/CPE ratio) levels of irrigation was higher than I1 (0.6 IW/CPE ratio) and I2 (0.8 IW/CPE ratio) levels of irrigation. The difference in water requirement between I3 (1.0 IW/CPE ratio) and I4 (1.2IW/CPE ratio) was not prominent because both these levels received three irrigation each. Likewise differences in between I3 and I4 were not prominent because both I3 and I4 irrigation levels received two irrigations. The water requirement was almost the same due to different levels of potassium. Significantly higher water use efficiency was in the treatment I2 (0.8 IW/CPE ratio). Potassium level K2 (K2O 100 kg ha-1) also record significant highest water use efficiency.
