Explanation:

The cultivation of high water-demand crops is an important factor contributing towards declining water levels in Punjab. The total water demand of a crop comprises ‘water required to meet Evopo-Transpiration (ET) process during the growing season and that required to meet evaporation demand of atmosphere. In the year 2005-06, crop water demand during kharif season was 50.5% of total water demand of state, whereas rabi season accounted for 31.3% of total water demand.Cropwise, paddy has the highest water demand of 37% followed by wheat (31.3%) and around 28 % by other crops including vegetables, fruits, fodder etc. The total ET demand (estimated by multiplying area under given crops with ET per unit area) of area under crops during 2005-06 has been estimated to be 4.56 mham. Thus, there is a water deficit of 1.43 mham (over the total supply of 3.13 mham) in the year 2005-06.
