Abstract
The objective of this experiment was to find out the effect of ridge direction and latex soil conditioner on potatoes organic matter contents on Typic Hapludands from Pangalengan. The experiment was conducted in Pangalengan, with elevation 1,600 meters above sea level and 30% of slope steepness. The experiment used a split plot design with 12 treatments and three replications. The main plot ridge direction consists of: in line with slope direction, in line with contour, and diagonal. The sub plot was latex concentration level as follow: 0%, 0.6%, 1.2% and 1.8%. The result of the experiment showed that there was no interaction effect between ridge direction and latex soil conditioner. The independent effect of latex gave no influence on organic matter contents.
