Role of agricultural extension in a commercialized agricultural system is different from such service in subsistence farming system. In the commercialized agriculture the extension service will mainly concentrate on the resourceful big farmers, with favourable environmental conditions and higher socio-economic status. Under the commercialized agriculture the number of farmers is to be reduced and the size of the farm land should be increased. This is a generally accepted concept in commercial agriculture. Do we have to accept this concept under each and every situation? We think the answer is “no”. By using improved technologies farmers can move towards commercial agriculture without considering the size of land. Under protected agriculture, farmers follow concepts of the commercial agriculture. Commercial livestock farming does not rely on the farm size except dairy farming.

However, the role of agricultural extension in the commercialized agricultural system is mainly dependent on the type and way of commercialization in a given society. We have to expect that agricultural extension services are supposed to fulfil many aims, from reducing rural poverty and improved livelihoods for rural households to increasing the overall production and contributing to foreign exchange earnings from exports. But the level and percentage of this contribution may vary from one situation to another.
