Agricultural Economics Unit
Promote Economic, Social & environmental Sustainability in the Rubber Sector
Agricultural Economics Unit mainly involves in socio-economic studies in the rubber sector as well as various economic analyses on rubber industry. Also, Agricultural Economics Unit conduct several research in collaboration with Biometry Section and assist to other research Department in various kind of analyses. It aims to provide necessary guidance to make rubber farming and processing a profitable venture.
