Abstract:
The field study conducted at College of Agriculture, Rajendranagar, Hyderabad on the response of Lucerne to irrigation scheduling, phosphorus and boron application indicated that the consumptive use of water (I year: 116.3 cm & II year: 128.9 cm) and the corresponding crop coefficients at different crop growth sub periods were high when the crop was irrigated at 1.25 IW/CPE ratio. The moisture extraction from 0 – 30 cm soil depth was also highest (I year: 67.8% and II year: 66.8%) with this treatment. Conversely, extraction of soil moisture from 30 – 60 cm soil depth was highest with 0.75 IW/CPE ratio with highest water use efficiency (I year: 27.2 and II year: 24.5 kg ha-mm^-1).
