Full text article. Also available at http://dx.doi.org/10.5539/jsd.v6n7p113The main concern in agricultural research is to ensure that research products are adopted by farmers. However, the rate of adoption is low. Most research on adoption rates are post-ante. The values of such research can be added if factors for adoption are ex-ante identified and measures taken to increase adoption. This study was conducted in Morogoro, Tanzania to ex-ante identify socio-economic characteristics that influence adoption of Integrated Lowland Rice Legume Technologies (ILRLT). The ILRLT included integration of rice (SARO variety), legumes (cow pea) water management (irrigation, rainfed and majaruba bunds), tillage (conventional and minimum) and fertilizers (UREA, TSP and MOP). Data were collected through questionnaire interviews to 200 representative farmers and key informants. Descriptive statistics, Multi-Criteria Analysis and a two functions adoption model were used to assess the suitability of ILRLT and analyze the likelihood of farmers to adopt. Results indicated that important criteria for rice variety preference and hence adoption are high prices (7.8%), good taste (6.1%), early maturity (4.8%), disease (3.2%) and drought tolerance (17.4%). ILRLT scored more (26.40%) than farmer’s (17.97%) in fulfilling criteria for rice legume variety preferences. ILRLT have a chance of being adopted to the maximum rate of 89.7%. Adoption is likely to be more with farmers who depend on irrigation than those who depend on rainfed rice farming.
