Adoption of BRRI Dhan47 in the Coastal Saline areas of Bangladesh

摘要

The main objective of this study was to determine the extent of adoption of BRRI dhan47 (A saline resistant High Yielding Variety (HYV) of rice have been developed very recently by Bangladesh Rice Research Institute (BRRI) suitable for cultivation in costal area) in Satkhira district. Data were collected from randomly selected 90 households? heads using pre-tested interview schedule during June to August, 2010. After collection, data were coded for processing and analysis. SPSS was used to perform the data analysis. Statistics like frequency counts and percentages as well as mean and standard deviation were calculated. Coefficients of correlation (r) was computed to find out the relationship between adoption of BRRI dhan47 and their selected socio-economic characteristics. Majority of the respondents were young aged (47.8%) having primary level education (45.6%), small family size (60%), medium farm size (51.1%), medium (75.6%) annual income, medium (63.3%) extension contact, poor (50%) training experience, high (38.9%) innovativeness, medium (70%) level knowledge on rice cultivation. Majority (52.3%) of the respondents had low adoption of BRRI dhan47 whereas 44.4% medium and only 3.3% under high adoption category. Farmer?s education, farm size, innovativeness, extension contact, knowledge on rice cultivation and annual family income showed significant and positive relationship with adoption of BRRI dhan47. Shattering, unavailability of salinity testing equipments and lack of rain water or irrigated water at tillering stage to escape salinity were the major problems faced by the farmers in cultivating BRRI dhan47. GO and NGOs should take immediate steps to disseminate salt tolerant rice varieties to bring the uncultivated areas under intensive cultivation as well as to ensure better livelihood of coastal farmers.
