Determination of yield response character function for Broccoli: A case study for Ayodhya region using FAO aqua crop model

Water is fast becoming an economically scarce resource in many areas of the world, especially in arid and semi-arid regions of the world including the Mediterranean. Water is a 'bulky' resource. This means that its economic value per unit weight or volume tends to be relatively low. Therefore, its conveyance entails a high cost per unit of volume and is often not economically viable over long distances unless a high marginal value can be obtained. The FAO Aqua Crop model, version 6.0 was used to simulate the above ground biomass, grain yield, canopy cover and Evapotranspiration. First of all, Aqua Crop model was run with default agronomic parameters and then validate for the agronomic parameters was conducted. These model was validated using field data of year 2022-23, model showed good agreement while validating the ETo and ETp with the regression correlation coefficient ranging from R2=0.406 respectively.
