Abstract
Improved crop varieties are crucial for enhancing global agricultural productivity. This study investigated the factors influencing the adoption of new varieties of irrigated cereals and oilseed crops (released between 2015 and 2022) among Iranian farmers. Data were collected from 1001 respondents using a multistage sampling procedure and analyzed via descriptive statistics and a probit regression model. The results revealed that 58% of the respondents had not adopted the improved varieties introduced during this period. Probit estimates identified several significant factors affecting adoption of new varieties including education, average annual income, access to improved seeds, seed supply system, participation in training courses, communication with pioneer farmers, communication with extension agents, use of social media, attitude towards the superiority of new varieties over the old ones, relative advantage, observability, and compatibility of improved varieties with the region conditions. To enhance the adoption of new varieties, implementation of enlightenment programs through competent extension services—such as participatory variety selection (PVS) farms or model farms—along with effective training courses is recommended. The availability of high-quality seeds at the right time for farmers can also increase the likelihood of adopting new varieties. The significant influence of training and extension agents underscores the vital role of structured outreach and education. Furthermore, the importance of varietal compatibility with regional conditions highlights the need to consider climate adaptability in breeding programs. Understanding these adoption factors can provide relevant research institutions with valuable feedback on their released varieties and insights into barriers to widespread adoption.
