Abstract

This research aimed to determine the effect of media composition leather waste coffea bokashi fertilizer on the growth of coffee seedlings in the nursery playing robusta nursery and determine the best composition that can replace the use of chemical fertilizer in the coffee nursery.

Each experimental unit was taken three (3) samples. These result indicate that treatment of bokashi fertilizer media leather waste coffe very significant effect on the dry weight of coffee seedlings, significant effect on plant height and weight of the wet, and no real effect on the number of leaves and stem diameter. Effect of medium composition leather waste coffe bokashi fertilizer best demonstarted high value crops 13.63 cm, wet weight of 1.82 g and 0.60 g dry weight. The use of leather waste coffee bokashi fertilizer is able to substitute inorganic fertilizer on seedling nursery play.
