Irrigation water is the most critical input and plays a crucial role for realizing the full potential of agriculture. However, water is very scarce and it needs its efficient use for irrigation with most commonly used surface irrigation systems and micro irrigation systems. The experiment conducted in summer groundnut (Arachis hypogaea L.) crop revealed that Sub surface irrigation system (a continuous emitting lateral buried at 30 cm soil depth) increased the highest of 69.33 per cent pod yield and 89.89 per cent fodder yield at the IW/CPE of 0.4 among all irrigation methods (Drip irrigation system, Micro sprinkler system, broad bed & furrow and Order irrigation system) at all irrigation levels( IW/CPE: 0.4, 0.5, 0.6 & 0.7) over border irrigation system. Sub surface irrigation system improved the highest of 72.78 for pod and 93.70 per cent WUE for fodder at the IW/CPE of 0.4 among all the irrigation methods and irrigation levels over border irrigation system.
