ABSTRACT
The success of the research that produced the Green Revolution has contributed to the widespread recognition of research as an essential component of agricultural development. Even so, it is not enough to recognize the need for investment in research. Funds must be allocated so that the parts of a research program logically relate to one another and the results of those research activities reach the farmers. This suggests an important role for extension work. This chapter concentrates mainly on research, but also treats extension activities—which are important where new technologies are so different that farmers cannot adopt them without assistance. 1
