Summary
Effect of soil fertility and farming practices on rice growth and yield of summer-autumn rice in the Mekong delta
Conducted field experiments were in 4 locations in 1999-2001. Rice yield of all 4 soils were enhanced by native soil N fertility. The effect of rice straw practices on soil properties and grain yield of wet season rice can not be concluded, long-term trials are needed to see the effect taking place. Raw seeding at the rate of 100kg/ha gave rice yield as high as broadcast seeding at the rate of 250kg/ha.
