Abstract

Consumptive use, water use, hydraulic parameters and yield of furrow irrigated raised bed system (FIRBS) in wheat were studied under three moisture regimes viz. 40, 50 and 60% maximum allowable depletion (MAD) at sub treatment of 15cm, 20cm and 25cm furrow depth. FIRBS resulted in maximum yield obtained in (29.61q/ha) were produced under 20 cm furrow depth with 50% MAD. The seasonal consumptive use varied between 246.00 to 372.42 mm. In furrow irrigated raised bed system 20 cm furrow depth at 40% MAD treatment recorded the highest value (372.42 mm). In furrow irrigated raised bed system the maximum water use efficiency found in 9.50 kg ha-1 mm-1 in 20 cm furrow depth under 50% MAD. The result revealed that advance time and recession curve in furrow irrigated raised bed system 15 cm furrow depth, and 20 cm furrow depth more parallel then 25 cm furrow depth. The parallelism of curves shows uniform distribution of water.
