IosbjareYrl;rca:kwnulo.:uniilurfrurauuriu' /Lessons Learned from Testing and Extrapolation

of Peanut after Rice without Irrigation of Khon Kaen Universit.y

AbstractKhon Kaen Univcnity has becn studying and testing peanut after rice cropping system

without irrigation sincc 1980/81l. Initially, farmers' practices at Surin province werc studies. Thc

tcchnique was tested at a sitc al. Khon Kaen and was found successful. A multilocational testing program

wils, then, launchcd in cooperation witr the Depaflrnent of Agriculrural Exrension. Experiences from

these work have indicatcd several principles which are important !o the development of technologics

appropriatcd to farmers' conditions and be accepmble to farmers. These include : l) Each technology

has iB own spccific condition for its appropriateness. In lhe developmenr and extrapoladon of a

technology, careful sr.udy must be made to really understand such a condirion. 2) studying exisring

tcchnology is very useful. 3) ln studying existing technology, ir is important !o undershnd rhe

dctailcd practices, and researchers should observe the real practices by their own eyes. Normally,

cach technology has only few critical poinr which need to be well understood.4) Some modifications

arc normally needos in transfering a technology from one place to lhe oth€rs. 5) Farmer-to-tarmer

transfcr of technology is quie useful and effrctive. 6) In testing of technology on farm, farmers

should be allowcd !o take part in $o dctermination of the treatmenB and practices. The test FeatmenB

should not be dcfinitely fixed, but some modifications should be allowed where appropriared. 7) Exisring

tcchnology can bc further improved. 8) Results of the rrials during tle leaming period should nor

be used in economic evaluation. During this period, evaluation should be based mainly on farmers'

opinion. 9) Different oplnrtunil.y costs of labor should be used in economic evaluation in differenr

situations. l0) Competition witr other economic crops is an imporant factor dctermining tie accepance

of thc test technology. 11) Only a certain level of understanding of the farmers' conditions could

be oblaincd from rapid area analysis. Before launching a large scale promotion of any technology

rn a given area, such Fchnology should be tested in that area for verification. 12) A study in a

limitcd scale could lead ro a wide scale policy implemenktion.
