Coffee is one of the plants that gave income to Indonesia. Currently, coffee plants are the pledge of several regions in Indonesia with their distinctiveness. However, coffee production is still needed to be improved due to its low production capacity. Increasing coffee production can be started from nurseries. Good seedling management can be done with application of NPK tablets and humic acid ferlilizer, which is influencing photosynthesis and photosynthates produced. The aim of the study was to determine dry matter partition through the dry weight of plant parts in coffee seedlings given NPK tablets and humic acid. The experiment was conducted on February to April 2017 at the Ciparanje Experimental Station, Faculty of Agriculture, Padjadjaran University. Randomized block design (RBD) was used in this experiment, consisted of nine treatments and repeated three times. The treatment was : without NPK tablets and humic acid; NPK Tablet 6 g; 10 mL humic acid; NPK Tablet 3 g + 5 mL Humic Acid; NPK Tablet 3 g + 10 mL humic acid; NPK tablet 3 g + 15 mL humic acid; NPK tablet 6 g + humic acid 5 mL; NPK tablet 6 g + 10 mL humic acid; NPK tablet 6 g + 15 mL Humic Acid. There was an effect of NPK tablets and humic acid on dry matter partition in the roots of coffee seedlings. NPK tablet 3 g and 10 mL humic acid gave the highest dry matter partition at the root.
