加纳国家农业研究系统正式发布24个高产、抗病虫害、早熟的木薯良种。然而，主要是小农户采用这些品种的比例非常低，导致产量和收入较低。本研究的目的是通过评估农民对木薯品种性状的偏好，促进改良木薯品种的开发和采用。该研究探讨了加纳木薯生产者对品种选择的决策行为以及他们对不同木薯性状的重视。它利用加纳 450 个木薯生产商的选择实验数据，采用混合 Logit 和潜在类别模型来估计木薯性状的价值。结果揭示了农民对木薯根系在土壤中的长期储存和木薯抗病性状的偏好。潜在类别模型显示，男性青年更有可能参与考虑土壤储存和多种用途的改良品种。除了高产和抗病性之外，农业研究系统还需要关注其他性状，以促进采用和增加产量。
Ghana's National Agricultural Research Systems have officially released 24 improved cassava varieties, which are high yielding, disease and pest resistant and early maturing. However, adoption of these varieties by mainly smallholder farmers is very low, leading to low yields and incomes. The purpose of this study was to contribute to the development and adoption of improved cassava varieties by assessing the preferences of farmers for cassava variety traits. The study explored Ghanaian cassava producers' decision-making behaviour towards variety selection and the values they place on different cassava traits. It employed mixed logit and latent class models to estimate the values place on cassava traits, by using choice experiment data of 450 cassava producers from Ghana. Results revealed farmers' preferences for longevity of root storage in the soil and disease resistance traits of cassava. The latent class model revealed that male youths were more likely to participate in improved varieties that take into account in-soil storage and multiple usages. The need for agricultural research systems to focus on other traits in addition to high yielding and disease resistance in order to boost adoption and increase production is imperative.
