Abstract
This research was compiled based on
Factorial Randomized Group Design (RBD) consisting of
2 factors with 3 groups to obtain 36 experimental units.
Each unit consists of 12 plants, 3 plants are taken as
samples, so that 432 plants in total with 144 plants as
samples. The first fator is the treatment of various types
of mulch with 4 levels, namely A1 = no mulch, A2 =
mulch rice husk, A3 = mulch banana stem and A4 = black
silver plastic mulch. The second factor is the treatment of
N, P and K anoragnik fertilizer with 3 levels, namely B1
= 15 g N, 15 g P2O5, 15 g K2O, B2 = 20 g N, 20 g P2O5,
20 g K2O and B3 = 25 g N, 25 g P2O5, 25 g K2O. The
results of the study that the treatment of various types of
mulch showed the dominant weeds in the cultivation of
Arabica coffee in Indonesia was Borreria alata, followed
by Elausine indica and Ageratum conyzoides. While the
lowest weed biomass was obtained in black silver plastic
mulch or N, P and K 15g: 15g: 15g
