Development of agro-climatic wheat yield model for Surat district, India using dimensional analysis

Abstract

In this study attempt is made to develop agro-climatic wheat yield model using dimensional analysis approach in which it is tried to include most significant parameters from the climate, soil and agricultural domain. Developed agro-climatic wheat yield model is different from the existing models due to consideration of above predominant parameters collectively which made it more sensitive towards climate change. Estimated wheat yield using developed model is compared with the actual yield for its validation which shows adequate conformity. Also the statistical performance of the model confirms its fitness, as discrepancy ratio is 1.095 and mean percentage error is 7.30E-05. Developed model while compared with the established models demonstrate better performance with ease in handling and hence recommended for wheat yield predictions.
