This paper examines whether rice adoption decision differs between sole decision-making and collaborative decision-making in which household members jointly decide on rice varietal selection. Overall, the results show that the majority of rice farmers currently cultivate older rice varieties. The average varietal age is 22 years. Adopters and non-adopters are significantly different in several observed characteristics; however, most of the differences are small. Specifically, between adopter and non-adopters, there is a statistically significant difference in the average varietal age of rice grown, the number of plots owned, varietal trait preferences, seed sources, contact with agricultural extension agents and risk preference. The results of the double-hurdle regression estimation are unconvincing for a difference between household decision-making structures, indicating that it does not matter who in the farm household makes the decisions on rice varietal selection. To encourage the adoption of improved rice varieties and reduce the average varietal age, the focus should be on improving access to agricultural land and extension contact. Besides, aligning varietal trait with farmers’ preferences and organising farm demonstrations is crucial.

孟加拉国的水稻品种选择：农户中的谁做决定重要吗？

本文研究了水稻采用决策在单独决策和家庭成员共同决定水稻品种选择的协作决策之间是否存在差异。总体而言，结果表明，大多数稻农目前种植的是较老的水稻品种。平均品种年龄为22岁。采用者和非采用者在几个观察到的特征上有显着差异；但是，大多数差异都很小。具体而言，在采用者和非采用者之间，水稻种植的平均品种年龄、拥有的地块数量、品种性状偏好、种子来源、与农业推广人员的接触和风险偏好存在统计学显着差异。双障碍回归估计的结果不能令人信服地说明家庭决策结构之间的差异，这表明农户中的谁做出水稻品种选择的决策并不重要。为鼓励采用改良水稻品种并降低平均品种年龄，重点应放在改善农业用地和推广联系上。此外，将品种性状与农民的喜好相结合，组织农场示范也很重要。
