Root traits of sugarcane cultivated by monoculture system in three orders of soil

Abstract

Sugarcane is a valuable crop and has been cultivated in Indonesia in a monoculture system since the Dutch colonial period. Cultivation of sugarcane in monoculture in the long term affects the condition of soil properties. This will affect plant growth, one of which is plant roots. This study aim was to determine the effect of long-Term sugarcane monoculture on sugarcane root conditions in three different soil orders. The research was conducted using two factors oversite design, soil order and duration of monoculture system. The observed soil parameters included soil physical and chemical properties such as bulk density, percentage of sand, silt, clay, porosity, pH H2O, organic matter, cation exchange capacity, NH4+, NO3-, Available P, Na, K, Ca, Mg, B and Zn. Root parameters observed were root fresh weight, the weight of root dry, root volume, the length of root, root cation exchange capacity and root surface area. The results showed that root volume, root length, root cation exchange capacity and root surface area were significantly impacted by the interaction of the soil order and the duration of monoculture system.
