Wageningen University and University of Nebraska Lincoln lead a NORAD funded project with Indonesian Oil Palm Research Institute (IOPRI) and Indonesian agency for agricultural research and development (IAARD). The objective is to assess yield gaps in smallholder and commercial oil palm plantations in 22 locations representing all oil palm cultivation areas in mineral soils in Indonesia. In phase I (2018-2019) the potential and water limited potential yields were simulated based on soil and weather data using PALMSIM. These were compared with actual yield data collected by IOPRI. In the second phase (2019-2023) the project works in 6 locations in each of which they follow daily oil palm related practices and yields of 200 independent smallholders. In each location seven paired demonstration plots are installed to compare vegetative development and yields of plots with best management practices with plots subject to farmers practices. The objectives are to show smallholders how to improve their yields and to investigate the relative contribution of different practices to the existing yield gaps. From the PPS group, the project is coordinated by Maja Slingerland. Willem Hekman and Rob van der Beuken worked in the first phase of the project. In the second phase, Mohamed Jabloun joined the team. Project output:
