Quinoa (Chenopodium quinoa Willd) is a drought- and salt-tolerant crop cultivated in arid and semi-arid regions to prevent yield reduction, maintaining relatively higher productivity under similar conditions compared to other crops. To evaluate the effects of various priming treatments on quinoa's growth indices, an experiment was conducted in a randomized complete block design (RCBD) with three replications at the Research Farm of the University of Kurdistan during the 2019 growing season. In this experiment priming treatments, including soaking seeds in solutions for 6 hours with potassium nitrate, potassium chloride, zinc sulfate, gibberellic acid, polyethylene glycol 6000, salicylic acid, humic acid, hydropriming, with unprimed seeds as control. Results indicated significant differences among treatments concerning dry matter accumulation, leaf area index, crop growth rate, and relative growth rate. The findings demonstrated that seed priming with salicylic acid positively affected growth parameters, with the maximum dry matter accumulation reaching 76.531 g/m², whereas the control (unprimed seeds) showed the lowest value at 67.425 g/m². Salicylic acid treatment increased dry matter accumulation by 19.95%. The zinc sulfate treatment induced the highest CGR and RGR in quinoaAdditionally, zinc sulfate treatment resulted in the highest crop growth rate and relative growth rate in quinoa plants. These outcomes suggest that seed priming can effectively enhance quinoa's growth performance and highlight its potential as a strategic crop for food security and sustainable development.
