The Department of Agricultural Extension in Thailand is promoting asparagus as an economic vegetable with a cultivation area of 12,200 rai. The harvest is done throughout the year, with farmers alternating rest periods. Some farmers have a purchase agreement with Thaniyama Siam Company Limited for the 2019/2020 sales, but due to the COVID-19 pandemic, the company could not renew the contract for 2020/2021. As a result, the company is exporting asparagus by sea due to high shipping costs, and has promised to buy all produce at the current price, adjusting as necessary.
