ABSTRACT

The land in Berastagi has a high erosion potential caused the high intensity of rainfall, steep slopes, and the cropping pattern is not good. Long-lasting erosion has lowered soil fertility and even reduced or eliminated soil tillage. This study aimed to obtain the appropriate intercropping pattern in the Berastagi dry land of Karo Regency, Indonesia. This study conducted a non-factorial randomized block design method with 5 replications. The treatment is in the form of farmers planting patterns and improved cropping patterns, namely P1, P2, P3, P4, and P5. The results showed that improved cropping patterns yielded higher rice equivalent yields compared to farmers' cropping patterns. Improved cropping patterns of P4, P2, and P3 are economically feasible in the Berastagi Karo dry land because they have a marginal B/C ratio above two, while the farmers' cropping pattern, namely intercropping of upland rice/cassava has the lowest B/C ratio of 1.72.
