Narrow-leaved lupine (Lupinus angustifolius) is a high-protein legume crop with significant agricultural potential, yet its cultivation faces challenges in stand establishment under arid conditions. This study aimed to evaluate the effects of growth regulators and priming techniques on lupine seed germination, plant development, and yield under field conditions in North Kazakhstan. The experiment was conducted on the ordinary chernozem soil with low nitrogen and phosphorus content. The climate is sharply continental, with moisture as a limiting factor. The tested lupine variety, Orlovsky Kormovoy, has a low alkaloid content (0.045%) and a vegetation period of 85–90 days. Four treatments were applied: control (dry seeds), hydropriming, treatment with the growth regulator Megamix Seeds, and priming in a Megamix Seeds nutrient solution containing essential macro- and micronutrients. A preliminary experiment determined optimal soaking duration for seeds in water and nutrient solution. Field parameters assessed included seed germination, biomass accumulation, root development, photosynthetic activity, and yield. Megamix Seeds treatment increased photosynthetic activity from 16.9 to 20.4 thousand m2 × days/ha and improved yield by 65% (from 8.65 to 14.28 c/ha). These findings highlight the potential of nutrient priming to enhance lupine productivity and resilience in arid regions.
