This study is aiming at assessing the role of technology transfer and participatory technology development on farmers’ crop yield and income in Shawa village of Zalingei locality during 2022/2023 cropping rainy season. Clustered random sampling technique applied. Demonstration farm was established in an area of 1.5 feddan. Farmers field schools (FFSs) of 25 men and women farmers selected. Participatory Technology Development (PTD) for men and women farmers was also developed in an area of 1.5 feddan. Improved seeds will be grown versus local check. Each treatment comprising NPK fertilizer micro dose (0. 0.3, 0.6 and 0.9 gram/ hole) randomly practiced. Fertilizer micro dose with percentage of 17-17-17 was added and mixed with seeds per hole at planting method. All farmers experienced to practical and theoretical farming of FFSs training in all research technical packages of land preparation, sowing date, seed preparation, seed dressing, thinning, weeding, water harvesting, soil conservation, pests and diseases control, seed production technologies, harvest and post harvest technologies. Results of partial crop budget revealed that all crops finically gave positive net returns. The highest yield kg/ha was obtained by Sorghum Wad-Ahmed 3500, Sorghum Butana with 3250, 3000 kg/ha for sorghum local and G/nut Gibaish, while the lowest yield/ha shown by sesame local (776 kg/ha). Therefore, the highest net returns was recorded by sorghum Butana (SDG 329048), sorghum wad-Ahmed (SDG 295477), sorghum local (SDG 269048) and G/nut Gibaish (SDG 108990). While the lowest net returns was computed by G/nut local with SDG 21,381. Results of marginal analysis revealed that sorghum Butana gave the highest MRR 1230. Results of Participatory Technology Development (PTD) of improved yields against local indicated that, the highest yield obtained by sorghum Wad-Ahmed and G/nut Gibaish (1100 and 950 kg/feddan), respectively. While the lowest yield obtained by sesame local (195 kg/feddan). The increased over decreased of improved versus local showed that sorghum wad-ahmed exceed local by 11%, millet Ashana 36%, sesame Promio 13% and groundnut Gibaish exceed local by 25%. The study recommended strengthening research extension farmers and enhancing farmers’ participatory technology development.
