A comparative analysis of some aspects of the training and visit system of agricultural extension in India
利用印度哈里亚纳邦的农户调查数据，比较培训与访问推广体系与传统推广体系在村级推广活动、知识扩散等方面的效果差异。
The article utilises recent farm survey data to assess the performance of the Training and Visit Extension system in one district in the state of Haryana (India) compared to a neighbouring district covered by an older extension system. The data show a significantly higher level of village‐level extension activity in the area covered by Training and Visit Extension, and this is compatible with the large number of staff and higher expenditure on extension under this system. The data also suggest that knowledge of improved practices, especially in wheat cultivation, diffused faster in the area covered by T & V extension.
