A field experiment was conducted during two consecutive Rabi seasons 2020-21 and 2021-22 at Students’ Instructional Farm of Chandra Shekhar Azad University of Agriculture and Technology, Kanpur, Uttar Pradesh, India. The field experiment allocated three irrigation scheduling namely: I1: two irrigations at CRI (crown root initiation) and Jointing stage, I2: three irrigations at CRI, Jointing and Booting stage and I3: Four irrigations at CRI, Tillering, Booting and Milking stage, two moisture conservation practices viz: M0: without mulching and M1: Organic mulch at the rate of 10 t ha-1 + Kaolin 6% spray and three nutrient management practices viz: N1: 100% Recommended dose of fertilizers (RDF) (150:60:40 kg ha-1 NPK), N2: 85% RDF + Farm yard manure (FYM) @ 5.0 t ha-1 and N3: 75% RDF + FYM @ 10.0 t ha-1. The field experiment was laid out in double split plot design with three replications. On pooled basis of two years experimentation the results indicated that, four irrigations at CRI, Tillering, Booting and Milking stage recorded significantly highest value of crop growth rate (CGR) (13.15 and 19.28 g m-2 day-1 at 30-60 and 60-90 days after sowing (DAS), respectively), grain yield (4381.60 kg ha-1) and consumptive use of water (457.39 mm) while, significantly highest water use efficiency (11.97 kg ha-1 mm) was received under two irrigations at CRI and Jointing stage over the rest of irrigation schedules. In respect of moisture conservation practices, organic mulch @ 10 t ha-1 + Kaolin 6% spray recorded significantly water use efficiency (11.41 kg ha-1 mm) compared to without mulching treatment while, highest consumptive use of water (380.72 mm) was recorded under without mulching. Integration of 85% RDF + FYM @ 5.0 t ha-1 recorded significantly maximum water use efficiency (10.99 kg ha-1 mm) compared to other treatments while, highest consumptive use of water (381.41 mm) was recorded under the treatment of 100% RDF.
