The treatment in question is k1 = 20 ml/ liter of water, k2 = 40 ml/ liter of water, k3 = 60 ml/ liter of water, k4 = 80 ml/ liter of water and k5 = 100 ml/ liter of water. The observed variables in this study are plant height (cm), root volume (cm3), the dry weight of the plant (g), wet stover weight on top of plant (g), wet stover weight on bottom of plant (g), the number of pods per plant, the dry weight of pods per plant (g) and dry weight of kernel per plant (g). The results showed that the using of liquid organic fertilizer on shrimp waste with dose 60 ml/liter can improve to growth and yield of peanut on peat soil.
