Abstract:
The present investigation was carried out during the Rabi seasons of 2018-2019 with the prime objective simulation of wheat crop of different irrigation levels using the DSSAT model after calibrating yield coefficients of wheat (PBW- 502) under the Argo-climatic conditions of Prayagraj. The experiment was laid out in a randomized design block (RBD) with three dates of sowings (D1, D2, and D3) and 5 irrigation levels (I1 to 15) as sub-plot treatment with three replications. The results obtained during the track of study, discovered that the different dates of sowing and irrigation had played, a significant role in deciding the yield of wheat. However, the date of sowing and irrigation variables affected the crop growth, development, and yield differences in different phenophases during its growth period. The results, regarding different dates of sowing as well as irrigation attributing characters of wheat variety as influenced by different treatments, showed a good agreement for simulated development and growth parameters for the Rabi wheat with their respective observed data five irrigations are applied at the time of CRI (I1) +Tillering (I2) +Jointing (I3) +Anthesis (I4) +Maturity (I5) proved to be better for higher growth and yield of the wheat at the period 2018-2019. On November 17 (D1) sowing, performed well whereas their performance was poor in the second and last sowing dates. A validated DSSAT model can be used to estimate phenophases, growth parameters, and yield of wheat.
