A field experiment was conducted to evaluate the effect of irrigation levels and mulch on yield attributing components and yield of groundnut (Arachis hypogaea L.) in study. The treatment comprised of 4 levels of irrigation viz., 0.4, 0.6, 0.8 and 1.0 ETc in the main plot and three mulch viz., no mulch (control), straw mulch and plastic mulch in the sub plot in split plot design. The soil was poor in organic carbon (0.11%), low in available nitrogen content (86.41 kg/ha) and medium in phosphorus (33.4 kg/ha) but high in available potassium (337.0 kg/ha) content and slightly alkaline in reaction (pH 8.4). The groundnut crop was grown by following the recommended package of practices for zone- IC (hyper arid partially irrigated western plain zone). Irrigation level at 1.0 ETc gave higher pods .per plant (44.16), pod yield (3395 kg/ha), kernel yield (2343 kg/ha), haulm yield (5530 kg/ha), biological yield (8925 kg/ha), harvest index (38.04%), seed index (42.60 gram). Plastic mulch recorded highest pods per plant (40.09), pod yield (2973 kg/ha), kernel yield (2052 kg/ha), haulm yield (4870 kg/ha), biological yield (7843 kg/ha), harvest index (37.89 %), seed index (41.31 gram). Pods per plant (44.64) and pod yield (3523 kg/ha) were highest under 1.0 ETc along with plastic mulch.
