Abstract: An experiment on rabi maize constituting three irrigation level viz., 0.4 IW/CPE ratio (I₁), 0.6 IW/CPE ratio (I₂) and 0.8 IW/CPE ratio (I₃) with 80 mm depth of irrigation at each irrigation with eight integrated nutrient management practices viz., N₁ (50% RDF), N₂ (100% RDF), N₃ (FYM @ 10 t ha^-1), N₄ (50% RDF + FYM @ 10 t ha^-1), N₅ (100% RDF + FYM @ 10 t ha^-1), N₆ (Bio-compost @ 10 t ha^-1), N₇ (50% RDF + Bio-compost @ 10 t ha^-1) and N₈ (100% RDF + Bio-compost @ 10 t ha^-1) was conducted at Instructional Farm, N.M. College of Agriculture, Navsari Agricultural University, Navsari during rabi season of 2010-2011.The results showed that irrigation level at 0.8 IW/CPE ratio recorded significantly higher grain (3708 kg ha^-1) and straw (9470 kg ha^-1) yield of maize over other level of irrigation. Moreover, Application of 100% RDF + Bio-compost @ 10 t ha^-1 (N₈) produced significantly the higher grain (4075 kg ha^-1) and straw (8872 kg ha^-1) yields than other integrated nutrient management practices.
