The experiment consisted of improved water management technology (0.6 IW/CPE ratio with gypsum application in splits) and conventional method (Irrigation once in 8-10 days) was conducted in Lower Bhavani Project (LBP) area. The mean total water use under improved irrigation was 486 mm which was considerably lesser than conventional method which utilized 639 mm water and quantity of water saving by 31.87 per cent. Averaging over locations, improved irrigation registered a mean yield of 1854 kg ha-1 which was significantly higher than surface irrigation and normal fertilizer application (1584 kg ha-1). The average yield increment by improved irrigation was 17.05 per cent over conventional method of irrigation. Higher net income and Benefit Cost ratio of Rs 57,371ha-1 and 2.64 were registered by improved irrigation as compared to Rs 39,916 ha-1 and 2.03 respectively under conventionally irrigated and fertilized groundnut. Thus it is evident that adoption of improved irrigation gained an additional mean net income of Rs. 17,455 ha-1 than conventional method.
