Cup-lump rubber

Cup-lump rubber is a highly significant agricultural product and economic crop in Thailand's Northeastern region (Isan), as most farmers prefer producing it over raw rubber sheets due to the savings in time and labor. Loei Province holds the top spot for the largest rubber plantation area in the Northeast, covering 949,140 rai, followed by Bueng Kan in second place with 886,280 rai, and Ubon Ratchathani in third with 620,959 rai.
