Abstract :

In order to determine the effect of humic acid and potassium fertilizer on the fresh and dry weight of heath and root dry weight , Length of root and Leaf Area Index (LAI) of mention plant, there was an Experiment using the plan of Compeletly Randomized Block Design with 3 replications and 12 treatments raised on factorial.the factors was 4 level of humic acid (0,5,10,15 kg/ha) and 3 level of potassium sulfate (0,50,100 kg/ha). During the experiment , Leaf Area Index, as well as plant fresh and dry weight , Length of root  and root dry weight was measured and analyzed. Results showed that the positive effect of humic acid and potassium on Leaf Area Index  by plant and increase dry and fresh weight ,root dr weight and Length of root . That treatment who had received the most amount of humic acid had significant difference in comparision of other treatments. Comparing treatment who had received the most amount of "Potassium"  had significant difference too. Comparing interaction between treatments, also indicate that treated plants with the highest amount of humic acid and putassium, had significant difference in comparision of other treatments.
