Abstract: A field experimental was conducted at Departmental Experimental Field, Department of Soil and Water Conservation, with three varieties of tuberose (Prajwal, Calcutta Single, Calcutta Double) along with three irrigation treatments on IW/CPE 0.4, 0.8, 1.0. The experiment showed that the total water requirement of three varieties of tuberose for the period March, 2009 to March-2010 were 626.06mm, 695.62mm and 751.27mm for the Prajwal, Calcutta single and Calcutta double, respectively. The irrigation requirements were 212.97lit, 247.15lit and 278.32lit for the Prajwal, Calcutta single and Calcutta double, respectively. The different irrigation schedules regardless of the crop varieties on the number of spike per plot were significant. The maximum spike per plot was recorded at 1.0 IW/CPE which gave about 33.15 number of spike per plot, which was superior to 0.8 IW/CPE (32.25) and 0.4 IW/CPE (30.57).
