The total cropland area amounts to 36 million ha in Indonesia (Table 1). About 900,000 ha cropland is potentially suitable for true shallot seed (TSS) systems based on stringent requirements for a number of soil and terrain characteristics. When more relaxed requirements are used for these characteristics, the suitable cropland area increases to almost 5 million ha (Table 1).
