Application of mulch under reduced water input to increase yield and water productivity of sweet corn in a lowland rice system

In these Southeast Asian experiments, mulching and reducing water input-by increasing irrigation interval before flowering-maintained or increased yield, and increased gross margin per hectare and per m3 water input. Particularly in areas with restricted water supply, and hence the need to reduce water input and increase water productivity, mulch allows a reduction in water input while also maintaining or increasing farm income from sweet corn.
