Generally, coastal sandy soil has low water content and potassium nutrients. One way tofix this is by adding organic matter and potassium fertilizers. Sugarcane press mudcompost as organic material acts as a slow-release fertilizer, it has an effect long enoughto support plant growth. A pot experiment was carried out to test the probability ofcombining sugarcane press mud compost and potassium fertilizer to improve thevegetative growth of corn plants in coastal sandy soils. This research was arranged in afactorial completely randomized design. The first factor is the dosages of sugarcane pressmud compost (0, 20, 25, 30, 35 tons per hectare). The second factor is the dosages ofpotassium fertilizer (0, 60, 90, and 120 kg K2O per hectare). After applying basal fertilizer(120 kg N per hectare and 90 kg P2O5 per hectare) and the treatment factor has beenapplied, the corn seed is planted and grown until vegetative growth or at flowering. Theresults showed that sugarcane press mud compost and potassium fertilizer interacted withthe effect of shoots fresh and dry weight, fresh weight, and root dry weight. Thecombination treatment of 25 tons of sugarcane press mud compost per hectare and 90 kgK2O per hectare (B2P2) resulted in the highest fresh weight and dry weight of shoots.Meanwhile, the combination of 0 tons of sugarcane press mud compost per hectare and120 kg K2O per hectare (B0P3) produced the highest fresh weight and plant roots' dryweight. The two treatments did not interact in influencing plant height and potassiumcontent in the corn leaf tissue. Both the sugarcane press mud treatment (20, 25, 30 and 35tons per hectare), and the application of potassium fertilizer (60 and 90 kg K2O perhectare) significantly increased plant height growth. The highest dosage of sugarcanepress mud compost (35 tons per hectare) and potassium fertilizer (120 kg K2O per hectare)produces potassium content in plant leaf tissue
