Add-on project "Yield Measurement" in Thailand completed

Prof. Waibel in cooperation with Prof. Eric Strobl, Switzerland; Prof. Sabine Liebenehm, Canada and Adjan Nopporn Tantisirin, Ubon Rathchathani University (UBU), Thailand has carried out a TVSEP add-on project in Thailand. The aim of the project is to verify satellite-based yield models by field-based yield measurement and subjective estimates of the farmers. In a total of 237 rice plots in TVSEP villages in the provinces of Ubon and Nakhon Phanom, the rice yield has been determined by exact GPS-based plot measurement, weighing the paddy in the field, right after harvest and taking moisture readings of paddy. Furthermore, farmers were asked to estimate the size of the plot and the expected production, prior to the harvesting operation. In addition, a short tablet-based questionnaire about the growth history of the plot was administered by the field technician and uploaded to the server at LUH.
