In this study; humic acid, which is one of the organic sources in soil, used in plant cultivation with increasing doses, the effects can be investigated over potassium. Research, Çanakkale Onsekiz Mart University, Department of Soil Science and Plant Nutrition nylon covered unheated greenhouse, was conducted between 08.03.2013 and 17.05.2013. As experimental material TKI Humas used and grown in pots Helen varieties of maize in the six different doses (0, 2, 4, 6, 8 and 10 L ha-1) of humic acid by applying the plants grown in the number of leaves, plant height, stem girth, root weight, body wet weight, root dry weight, shoot dry weight, potassium in the soil can be obtained, and in plant roots total potassium parameters were studied in the plant body. As a result of experiment, the amount of potassium by the plant received HA numerically increasing dosage increased but this increase was observed to be at a statistically insignificant was determined.
