Concerted action on yield gap, supported by the most relevant research groups in WUR. The aim is to integrate initiatives to identify the potential contribution of input factors to the yield gap of fodder crops. This is important in order to be able to advise farmers on the optimal timing, spacing and application rate of inputs that need to be applied on their farm.
Efficient and sustainable dairy farms are based on excellent fodder crops production. Excellent fodder crop production approaches the potential crop yield if the gap between practical and potential yield is low. The yield gap of grass and maize in the (Dutch) common practice amounts to approximately 20% of the potential yield.
This proposal links several initiatives to identify the main constraints and technical problems faced by dairy farmers to fully use the available resources and bridge the yield gap in fodder crop production systems.
