Quinoa is recognized as a complete, nutritious, and healthy food with considerable genetic variability and adaptability to adverse soil and climatic conditions. Successful quinoa cultivation relies significantly on the sowing method employed. This study, conducted during the 2020/2021 cropping season at the Experimental Annex of the Technical Institute for the Development of Saharan Agriculture in Feliache, Biskra, aimed to evaluate the impact of mechanical and manual (broadcasting, rows, and group) sowing methods on the yield and yield components of quinoa. The experiment, utilizing the GIZA II variety, was designed in a randomized complete block format with three replications. Statistical analysis revealed that the broadcasting method yielded significantly greater plant numbers/m2and grain yield/ha compared to other methods. Noteworthy variations among treatments were observed concerning yield attributes, with mechanical sowing producing the highest number of plants, maximum panicles/plant, greater main panicle weight, and grain yield/plant. However, no significant effects of sowing methods on dry weight/plant, thousand grains weight, and harvest index were detected. Moreover, significant and positive correlations were identified between plant number and seed grain yield. Seed yield/plant exhibited significant positive correlations with plant height, panicles/plant, dry weight/plant, and main panicle weight. The results affirm that mechanical sowing outperformed other methods, showcasing superior outcomes.
