The field data (2020-21 and 2021-22) of DFRS farm, Solapur, Maharashtra, India comprising four sowing windows in Rabi season i.e. S₁ - 36 MW (03-09 Sept.), S₂ - 38 MW (17-23 Sept.), S₃ - 40 MW (01-07 Oct.) and S₄ - 42 MW (15-21) and varieties (Maldandi, Mauli and Yashoda) through the field experiment laid out split plot design were used for model validation.

The simulated and observed mean number of days taken to physiological maturity both the year 2020 and 2021, the RMSE (Root Mean Square Error) values for simulations were 11.51, 12.75, 13.92 and 12.80, 14.06, 15.26 for Maldandi (V₁), Mauli (V₂) and Yashodha (V₃) respectively.

Likewise, the simulation performance of the model lowest % error range found statistically good in S₃V₁ (40 MW) (3.3 to 6.1%) followed by overall rest of the treatment.
