Abstract

he conservation tillage system which includes minimum and non-tillage tillage becomes an alternative land preparation that can maintain high productivity. One thing that determines the success of conservation tillage is to restore plant residues after harvest as a source of organic material in the form of mulch to maintain the physical properties of the soil. This study aims to determine the effect of tillage and nitrogen fertilization systems on the soil prorerties and corn yeild. The study was conducted using a Randomized Block Design (RBD) which was arranged factorially with 4 replications. The first factor is a long-term tillage system (T1 = Intensive tillage, T2 = Minimum tillage, T3 = No tillage) and the second factor was long-term nitrogen fertilization (N0 = 0 kg N ha). The data obtained will be tested for homogeneity by the Bartlet test and the additivity of the data was tested by the Tukey Test. The results showed that long-term tillage and fertilization systems did not affect the physical properties of the soil, namely bulk density, soil porosity, soil texture, and soil structure. The highest soil organic carbon was obtained when the treatment of the minimum soil combined with of 200 kg N ha -1 and N1 = 200 kg N ha-1 treatment was 1.56%. The highest corn yield was obtained from the treatment of the minimum tillage and no tillage combined with nitrogen fertilization of 200 kg N ha-1.
