The study was carried out to determine the farmers’ adoption behavior on wheat and paddy production technologies. The farmers were selected from Samasripur, Darbhanga and Muzaffarpur districts who demonstrated wheat and paddy technologies during 2002-03 to 2004-05. Findings of the study revealed that 53.75 per cent respondents had adopted the wheat production technology at higher level followed by 31.25 per cent and 15.00 per cent respondents had adopted the wheat production technology at medium and low level respectively. Also in paddy, 60.00 per cent respondents had adopted the production technology at higher level followed by 21.25 per cent and 18.75 per cent respondents had adopted the paddy production technology at medium and low level respectively. The major technical, resource and market related constraints perceived by farmers in wheat and paddy were perceived by farmers were non-availability of quality seeds of wheat, non-availability of rubber milling facility in their locality for rice processing, breakage of grain during milling/ processing, lack of transportation facilities, and lack of market facility
