Abstract
Indigenous Knowledge base tree crop farming system is prevalent from time immemorial to Khasi community in Bangladesh. This is their main subsistence and earning economy. However, environmental degradation with global warming and the shortage of natural resources has threatened the overall cultivation system. The topsoil of landscape with water bodies and ground water are not adequate for watering in the field. Therefore, it is burning question how Khasi mange and organize tree-crop farming in the field and what types of initiates are taken by them to grow tree crops. To explore these issues a qualitative approach and participant observation method with in-depth interviewing techniques, group discussion and key informant methods were employed to elicit data from the field. The collected data have been analyzed in inductive approach and categorized it from various chunks of information as objectives. The findings showed that traditional knowledge as local knowledge of the Khasi has been modified to the context different topographical structure and texture of soil with hill surrounding natural setting considering the local ecology, environment and biodiversities. The obtained findings uphold some empirical issues of indigenous practices with scientific practice of tree crop cultivation for getting soil moisture, fluid and water, which derives from rotted tree-twigs. While organic wastes and the foliage are not adequate, they use harvested rainwater, shallow-well water and ground water by using diverse ways and techniques. The watering and irrigation practice in the tree-fields are administered by the influence of modern irrigation inputs, including traditional Knowledge.
