The present investigation was carried out to study on soil moisture depletion pattern of wheat to different irrigation scheduling. The experiment was conducted during the period from November to April in 2016-17 and 2017-18 in the experiment field of Research Farm at BSP (Soybean) unit, Department of Physics and Agro-meteorology, College of Agricultural Engineering, J.N.K.V.V, Jabalpur (M.P.).The experiment was laid out in Double Split Plot Design with three replication. Main treatment: Sowing date (3 levels at 15 days interval): D1: 30 November; D2: 15 December; D3: 30 December. Sub plot treatment: Varieties (2 varieties used): V1: GW-366 and V2: MP1202. Sub-sub plot treatment: Irrigation (3 levels): I1: crown root initiation +flowering stage; I2: crown root initiation + late jointing +milking stage; I3: crown root initiation+ tillering+ flowering+ milking stage. Soil moisture depletion pattern of wheat varieties are not showing differently as for as moisture use is concerned. Irrigation level I3 was always registered greater moisture content throughout the growing period with significant over other two, but (I2) can save irrigation water with only marginal yield reduction compared to (I3) irrigation treatment. The results showed that in treatment (I2) favorable soil moisture was maintained and optimum water productivity and yield of wheat was recorded with marginal reduction in yield and save water as compared to (I3).
