Effect of irrigation level and integrated nutrient management on growth and yield of Rabi maize (Zea mays L.)

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.
