Drill sowing of rice is cost effective and can provide several advantages over aerial sowing. These include; water savings, no wind or muddy water problems, changed weed spectrum and reduced duck and snail issues. Water savings are achieved by lower evaporation losses due to the reduced period of ponding.
In recent years there has been an improvement in the level of understanding in the management of drill sown rice. Recent research and new technologies have also led to improvements in managing the establishment of drill sown rice.
