Abstract

The primary objective of this research was to analyze the challenges in the dissemination of improved varieties of irrigated cereals and oilseeds introduced between 2011-2022 from the perspective of end-users (farmers). This study is field-based survey research. Data collection was conducted using questionnaires. The results of this study revealed that 58% of the participating farmers were classified as non-adopters of the newly introduced domestic varieties. Overall, although 60% of the rice varieties introduced to farmers over the past five years were varieties released after 2011, more than 70% of rice farmers cultivated local rice varieties (primarily the Hashemi variety) either exclusively or alongside other improved varieties during this period. For barley, the relatively new domestic varieties received favorable acceptance. However, the adoption of improved domestic rapeseed varieties was unsatisfactory, as all surveyed rapeseed farmers had cultivated imported varieties over the past five years. Regarding maize, a total of 22 varieties were grown by farmers, of which 17 (77.3%) were imported. The findings also indicate that information about newly introduced varieties is not communicated to farmers in a timely manner. Even when farmers are aware of a new domestic variety and willing to cultivate it, they often lack access to sufficient seeds at the right time. Key solutions proposed by farmers to enhance the dissemination and adoption of newly introduced varieties include: Introducing market-preferred varieties (with desirable taste, aroma, and cooking quality, particularly for rice), conducting training programs on new varieties, their characteristics, and cultivation practices, implementing PVS (Participatory Variety Selection) schemes or demonstration farms to showcase and compare the quality and yield of new varieties.
