The lack of transfer of technology from research system to the client system is the main problem in increasing agricultural production in the developing world. Still there is a wide gap between attained technical know-how and its utilization in the field of common farmers. The present rate of agricultural production can be doubled if the available groundnut production technologies are brought to bear with production process and programme. This require the steady flow of information from the scientist to the millions of farmers. Moreover, inputs are needed to be used scientifically. This is possible through the demonstration as it is an important and appropriate extension method which make it possible to disseminate technology to the user farmers. Keeping this fact in view with the government of India launched frontline demonstration programme for oilseed crop under auspicious of oilseed mission. It has played significant role in increasing the knowledge and adoption of recommended groundnut production technologies by the groundnut growers. Considering this, the present investigation is entitled as the book is suggesting in the title.
