Permanent beds on rice farms

The objective of this research is to assess the performance of rice and crops following rice on permanent lateral raised beds compared with conventional flat irrigation layouts.

Permanent lateral beds in bays potentially offer several advantages over cropping on flat layouts, leading to:

  • increased opportunity to easily switch between rice and other furrow irrigated crops
  • increased water productivity and yields for rice and subsequent crops
  • easier water management
  • quicker field drying, greater trafficability and the increased use of ground equipment
  • reduced recycling (pumping) costs in furrow irrigated crops.

The research reported here is part of a large project involving field experiments in varying irrigation systems in Australia and north west India, computer modelling of crop growth and development, and economic analysis of different cropping systems.
