Abstract

The bare intensife tillage applied on agricultural land can drastically reduce soil quality. One of the efforts to prevent it is by applying mulch and conservation tillage. The objective of this study was to determine the effect of minimum tillage and mulch on soil aggregate stability and root biomass. This study was designed in the field using a randomized block design (RBD) with 2 factors and 4 repetitions. The first factor was tillage (minimum tillage (T1) and intensife tillage (T2)). The second factor was mullch (without mulch (M1) and 5 Mg mulch ha-1 (M2)). The aggregate stability was determinate using water-drop method (WDM). The results showed that the minimum tillage affected the increasing soil aggregate stability of the 6 mm and 3 mm diameter aggregate before land preparation and after harvesting, except, the 3 mm diameter aggregate before land preparation. The minimum tillage also increased root biomass during the vegetative period of the plant. The treatment of 5 Mg mulch ha-1 affected in increasing the soil aggregate stability of 3 mm diameter aggregate after harvest but not the soil of 6 mm diameter aggregate. No interaction was found between the minimum tillage and 5 Mg mulch ha-1 on soil aggregate stability and root biomass.
