6.5 - 6.8 and pH 4.1 – 4.6. The research adopted group random design with 18 varieties of rice as
plant to test. The parameter to analyze such as height of plant, number of saplings, number of
productive saplings, length of grains, numbers of grains, number of decomposed grains, grains
production and wet weight and dried weight of roots.
The result of research indicated amongst different of varieties as tested showed a significant
