A field experiment was conducted at Agricultural College farm, Upper Krishna Project Command, Bheemarayanagudi on deep black soils during 2000-2001 to find out the response of rabi groundnut to irrigation schedules (5, 4 and 3 irrigations at critical stages and fortnightly interval), organics (FYM 8 t ha-1, sunflower stalk 5 t ha-1, dhaincha green manuring 5 t ha-1 and no organics) and fertility levels (100, 75 and 50 per cent of RDF - 25:75:25 kg ha-1, N, P2O5, K2O). The results revealed that crop receiving four irrigations of 6 cm depth, each scheduled at critical stages (pre-flowering, pegging, pod formation and pod filling stages) and dhaincha green manuring along with RDF recorded significantly higher pod yield (22.1 q ha-1), net returns (Rs. 20,548 ha-1) and B:C ratio (3.01) over rest of the treatment combinations. Green manuring of dhaincha also reduced the seasonal consumptive use of water (504 mm) over control (no organics) (523 mm).
