The state of West Bengal has 2.7 per cent of geographical area and 7.5 per cent of water resources. Among the various natural resources, water is considered the most precious and vulnerable input for sustain biological productivity, maintain environmental quality and sustain plant, animal, human health and augmented agricultural production., a field experiment was conducted at the Regional Research Station, Gayeshpur, BCKV during the winter season of 2013-2014 to assess water Requirement and water use efficiency of tuberose. The application of irrigation based on IW/CPE ratio revealed that plant height of tuberose consistently increased with the increasing moisture regimes. However, the highest plant height of 54.97 was obtained with the irrigation at 1.0IW/CPE ratio, which was superior to other irrigation treatments. Maximum plant height, irrespective of irrigation schedules was recorded by Prajwal variety, which was superior to other varieties namely Calcutta single and Calcutta double were at par under study. The interaction effects between the irrigation schedule and the varieties were not significant. From this study it is indicated that the economic yield of tuberose under higher moisture level was not high enough/ or optimal in response to the higher irrigation regimes, thereby giving lesser gross return as well as the net return values as compared to the lower moisture regime.
