A new study has been initiated at Gabon Living Lab to explore the growth of okra using various innovative substrates such as coffee parchment and even coconut husks. To follow the innovative system developed within INCiTiS-FOOD all are irrigated with fish water through a drip system. This research aims to determine which substrates best support okra cultivation. The findings will provide valuable insights into eco-friendly farming techniques and their potential to enhance crop productivity.
