The effects of bed planting on the water use efficiency of wheat cv. HD 2285 were determined in a field experiment conducted in New Delhi, India during 1999-2002. Bed planting resulted in better soil physical properties, hence increasing the root length density of the crop by 30%. Bed planting also reduced the water applied during the first, second and third irrigation by 30, 20 and 5% respectively. Crop water index showed that the crop experienced the same level of water stress in bed and conventional system, although lesser water was applied in the bed planting system. Manual weeding was more effective in bed than the conventional planting system. The total water use of the crop was reduced by 5 cm, whereas yield and water use efficiency increased by 0.22 and 0/03 t/ha, respectively.
