Initial results show the positive impact of improved water management

April 29, 2011

In Bamé (Benin), field experiments are conducted to assess the impact of improved water management on rice yields. A lay-out is set-up that allows testing the traditional way of water management versus continuous inundation. Moreover, the effect of fertilizer application is tested. In December-January the fields were harvested for the first time. Paddy yields from the entire fields (10×10 meter) were weighted and analyzed.

The figure below provides a map of the experimental lay-out. The measured paddy yields vary from 1.9 to 4.9 ton per hectare. However, it can be witnessed that the yields in the fields under ‘sawah’ management are significantly higher. The impact of fertilizer application is, however, much lower. In the coming months, these results will be further analyzed together with the results from the second season.
