Abstract/ Executive Summary:

This paper reports on an investigation concerning patterns and intensity of adoption of the high yielding varieties HYVs) of boro (winter) rice among the opinion leaders and the farmers in a progressive village and in a less progressive village of Bangladesh. In case of the less progressive village, the intensity of adoption of the HYVs of boro rice increased with the increase in the size of the irrigated area. However, for the farmers of the progressive village an opposite pattern of decreased intensity of adoption of the HYVs of boro in relation to the size of the irrigated area was observed. For all the farmers increase in the intensity of adoption of the HYVs of boro rice could be perfectly attributed to the percentage of the irrigated area showing the decisive importance of water in the cultivation of winter rice. The results of stepwise regression combining both the economic and non-economic factors and the economic factors as a set re-established the above finding. However, as a set, the non-economic factors contributed to a various but generally low extent to the explanation of the variance of intensity of adoption of the HYVs of Boro rice.

Program Area: Socio-economic and Policy

Commodity: Rice

Objectives:

To reports on an investigation concerning patterns and intensity of adoption of the high yielding varieties HYVs) of boro (winter) rice

Methodology:

The field data collection for this study was conducted during 1989 in Muktagacha Thana (sub-district) of Mymensingh district, Bangladesh. The Unions (similar to precinct), surveyed in this study, from the same Thana, represent two areas in different stages of the development. They were selected randomly from two groups of Unions - relatively progressive and less progressive. These Unions had similar physical, agro-climatic, socio-cultural, demographic and religious make up and topographical characteristics. Also, identical programmes of technological change were introduced by the Department of Agricultural Extension in the selected Unions almost at the same time. The relative progressiveness of the villages was determined using several criteria : proximity to the main road transport system; markets; towns; extension Centre; closeness to the facilities such as education, health care, services; judgments by the experts; differences in the rate of technological adoption and other qualitative and quantitative criteria (Hossain, 1992). At a later stage two villages were selected for this study. One village was chosen from the progressive Union purposely because of the factors considered above for relative progressiveness. Another village was selected randomlyout of 28 villages of the less progressive Union which was far away from those modern facilities. Sixteen non-economic (age, farming experience, personal education, family education, family size, conservation concern, political knowledge, cosmopolite ness, fatalism, achievement motivation, managerial skill, local interaction, social participation, innovation proneness, exposure to modern farming information, and contact with extension worker) and I 1 economic (own farm area, total farm area, tenancy, absolute subsistence pressure, relative subsistence pressure, agricultural worker, availability of labour, herd size, area irrigated, percentage area irrigated, and economic level of living) independent variables were included in the study to explain the situations of the farmers. Both dependent and independent variables (which finally appeared in the regression models) and their measurements are given in the subsequent section. Unidimensionality of the indexed independent variables were ascertained by using factor analysis following the extraction of the first factor pattern from un rotated factor matrix (Tabachnick and Fidell, 1989). For those indexed variables Cronbach's alpha reliability procedure was employed using the internal consistency method for assessing reliability (Carmines and Zeller, 1979). Ordinary least Square and stepwise regression procedure were used to ascertain the contribution of the independent variable(s) on the dependent variables. In this paper only Boro (winter) HYVs of rice cultivation is considered. Winter in Bangladesh is dry with very low precipitation. Correlation matrices are also provided to check the multicollnearity of the selected variables.

Achievement/Findings:

The results of stepwise regression combining both the economic and non-economic factors and the economic factors as a set re-established the finding. However, as a set, the non-economic factors contributed to a various but generally low extent to the explanation of the variance of intensity of adoption of the HYVs of Boro rice.
