Abstract

The needs of plant potassium can be done by adding banana stem liquid organic fertilizer and coconut husk liquid organic fertilizer which contain a lot of K elements. To determine the increase in nutrient potassium and its effect on the growth of maize to Alfisols. This research was carried out in the form of a separate plot design consisting of the main plot P1 (banana stem liquid organic fertilizer), P2 (coconut husk liquid organic fertilizer) and tillers plots d0 (0 ml), d2 (75 ml), d1 (50 ml), d3 (100 ml) obtained 8 treatment combinations and repeated 3 times. Liquid organic fertilizer for banana stems and coconut husk can increase the availability of K in the soil. At a dose of 100 ml of coconut husk liquid organic fertilizer has a significant effect on the increase in organic C, Cation exchange capacity (CEC), Na and it also be able to increase the soil pH of K-available, Ca-dd and shows the highest average in increasing plant height and plant dry weight. The application of coconut husk liquid organic fertilizer has a significant effect on K content in plants, plant height. However, it has no effect on the dose given.
