It is very important to evaluate traits of cassava clones, especially early harvest cassava clones under different environments of fertilizer types. Until now, study of genetics variance in early harvest cassava is still very rare. Accordingly, the objective of this study was to evaluate the genetics parameter of early harvest cassava clones under different fertilizer types. Treatments were arranged by factorial design (3x4) in completely randomized block design with two reps. The first factor was three cassava clones as Soponyono, local Waxy (early harvest clone), and UJ5 (conventional clone). The second factor was four fertilizer types as inorganic fertilizer of KCl, organic fertilizer of K, cow manure, modified EM (bio fertilizer). The organic fertilizer of K was from cassava fresh stem that was finely small chipping as source of K. Observations of variables were carried out when the plants were 6 months old after planting. The observed variables were plant height, number of green leaves, total number of leaves, stem weight, fresh leaf weight, number of roots, number of storage root, storage root weight. The result was storage root number and storage root weight showed negative genetic variation. It means that storage root traits were influenced by environment as fertilizer types.
