Development of Indigenous Yield Monitoring Device for Grain Combine Harvester

Assessing variability, managing variability and evaluation are three basic steps for precision farming. Therefore, to assess the yield variability or to get the first step of precision farming, there was a need to develop yield monitoring device to assess the variability within a field. To spread the use of yield monitoring combines in India, it was necessary to develop an indigenous yield monitor for locally manufactured combines. An indigenous yield monitor was developed by assembling the designed/selected components on the combine harvester. The developed indigenous yield monitor was evaluated for paddy crop to measure yield variability of crop within the field.
