Study on the Biomass Production Assessment of Wheat Varieties under Semi-arid Conditions of Rajasthan through Using Info Crop Model

The current study used a three-replication double split plot design with 36 treatment combinations, including main plots: irrigation levels (0.6 Etc, 0.8 Etc, 1.0 ETc, and 1.2 ETc), sub plots: varieties (Raj 4120, Raj 4079, and Raj 4238), and sub-sub plots: sowing dates (15th Nov., 30th Nov., and 15th Dec.). The Info Crop model was calibrated and verified using experimental data from three wheat cultivars (Raj 4120, Raj 4079, and Raj 4238) sown at various times and with varying irrigation schedules. The model’s performance was assessed using average error (Bias), root mean square error (RMSE), Normalized RMSE (nRMSE), and index of agreement (d), with the simulated and measured durations agreeing well. Based on these findings, it can be stated that the model accurately predicted growth characteristics such as leaf area index, biomass output, and yield, and that it reflected the temporal patterns of yield variability relatively well when compared to observed field data (error percent between 10-20).
