摘要

On-farm conservation is a type of in-situ conservation of crop diversity which is best done through the maintenance of farming systems. Since farmers, on the basis of their local knowledge, shape the crop diversity, on-farm conservation also involves traditional knowledge and practical skills of the farmers. This paper describes the role of farmers in on-farm conservation of rice diversity in a village in Barak Valley, North-East India. An inventory of rice diversity was made and a total of 25 traditional cultivars were recorded from the study site. The role of farmers' knowledge of soil was also assessed. In the area which is predominantly sandy in texture, the folk soil taxonomy, which helps the farmers in the management of crop diversity, was also prevalent. Analysis of soil characteristics showed that the higher diversity of traditional cultivars was due to the heterogeneity and poor quality of the soil. This criterion was based on the assumption that the more heterogeneous the environment, the more is the varietal diversity. Thus farmers in more fragile ecosystem maintain more crop diversity to adapt to the heterogenous environment. It is important to note that small holder and marginal farmers must be encouraged to grow traditional varieties and due recognition has to be given to the traditional knowledge of these 'agroecosystem people' for managing this agrobiodiversity.
