Abstract

An experiment was conducted at Punjab Agricultural University, Ludhiana during 2014-15 and 2015-16, keeping four sowing dates {25th Oct (D₁), 10th Nov (D₂), 25th Nov (D₃) and 10th Dec (D₄)} in main plots and five irrigation schedules {irrigation at 15 (FC₁₅), 25 (FC₂₅), 35 (FC₃₅) and 45 (FC₄₅) % depletion of soil moisture from field capacity (FC) and a conventional practice} in sub plots. The objective of the study was to evaluate the performance of CERES-Wheat model for simulating yield and water use under varying planting and soil moisture regimes. The simulated and observed grain yield was higher in D₁, with irrigation applied at FC₁₅ as compared to all other sowing date and irrigation regime combinations. Simulated grain yield decreased by 19% with delay in sowing from 25th October to 10th December because of 8% reduction in simulated crop evapotranspiration. Simulated evapotranspiration decreased by 16%, wheat grain yield by 23% and water productivity by 15% in drip irrigation at 45% depletion from field capacity as compared to drip irrigation at 15% of field capacity. It was further revealed that the model performed well in simulating the phenology, water use and yield of wheat.
