\textbf{Abstract}
\begin{abstract}
\normalsize{
Sorghum is the most important cereal crop and a staple food in the Sudan. Widely grown in the Sudanese rainfed areas, the production of the crop is highly threatened by a series of biotic, abiotic and socio"=economic constraints leading to a constantly declining yield per hectare. The aim of this study is to identify and assess opportunities, constraints, local knowledge and perceptions of sorghum producers with a special focus on the endogenous local mechanisms adopted to combat and cope with \textit{Striga }infestation. Data are collected using a multistage stratified sampling technique covering 326 households from 17 villages, eight administrative localities from three different states within the rainfed areas of the Sudan, namely El-Gadarif, North Kordofan and El-Gezira. Descriptive statistics, cross tabulations and inferential statistics are applied to the collected data as methods of analysis. Preliminary results of the analysis indicate that local varieties of sorghum that are not licensed by Agricultural Research Cooperation and the Ministry of Agriculture are widely grown by farmers. The majority of the interviewed farmers prefer growing seeds that they usually buy from other farmers. Responding to the question on the main constraints facing the production of sorghum, respondents listed \textit{Striga }first, followed by pests and diseases and limited access to improved seeds and credit. When it comes to the justification of their decision on not to adopt \textit{Striga }control technologies on sorghum, the majority of the farmers indicated their lack of adequate information about the technology. However, they also insisted on that they prefer low"=cost \textit{Striga }management measures. Apart from combatting Striga, farmers' non"=adoption of other productivity"=enhancing technologies such as improved seed varieties, fertilisers and herbicides was justified on the bases of their costs given the lower producer price of the crop.
