The damage, up from 425,000 francs the previous year, was primarily due to the cold weather of winter 2012/13 which forced boar to leave the forests and invade farmers' fields, reported Swiss news agency ATS.
The damage caused by wild boar has been a controversial subject in the canton for some years, it reports.
For the last two years the canton has shortened the period of time under which boar are protected from hunters. Now, even young boar are allowed to be shot if they wander outside forests during the protective period.
Last year hunters of the canton shot 1,200 boar, down from 1,600 in 2012.
The authorities have recently invested in infrared tracking devices to help hunters find boar at night.
