Synopsis Government of India proposed many projects/schemes to improve the socio-economic conditions of farmers in India and wanted to transfer technologies from the research stations to farmers' fields. The programme like national demonstration, Operational Research Project, Lab to Land, watershed management, etc, and Krishi Vigyan Kendra was initiated during the year 1974 at Madur, Karaikal, Pondicherry under the host organization of Government of Pondicherry and subsequently placed under the administrative control of Tamil Nadu Agricultural University. Based on the activities of this KVK, Planning Commission approved the proposal of the ICAR to establish 18 KVKs during the Fifth Five Year Plan. The strength of the KVKs reached to 541 as on today and it may be about 585 because each district in the country will have one KVK, irrespective of the size and area of the district. The main functions of the KVKs are to conduct training programmes, on-farm trials, front line demonstrations, extension education, livelihood programmes, etc. The jurisdiction of the KVK is only within the district. This is hoped to cater the needs of farmers, farm women, rural youth, artisans, etc. in rural areas. There is no proper documentation till now. Hence this book is proposed to cover all aspects for the benefit of the scientists, extension workers, administrators, planners, etc. The KVKs are managed by State Agricultural Universities, ICAR Institutions, Non-Governmental Organizations, etc. These are wholly funded by Indian Council of Agricultural Research so as to improve the knowledge of the farmers and other rural people in technologies of agriculture and allied enterprises for improving productivities and profitabilities of farming activities so as to improve the socioeconomic conditions of the rural people.
