Rapeseed (Brassica napus L.), ranked as the second most crucial oil crop globally, holds a prominent position in world agriculture, playing a pivotal role in meeting the increasing demand for edible oil and biodiesel. Pursuing sustainable goals in rapeseed production systems becomes paramount to addressing this growing demand. This study focuses on cultivar selection, a key factor for decision-makers striving to establish sustainable production systems. The investigation, conducted in Mazandaran province, Iran, the country's third-largest rapeseed producer, examines five commonly used cultivars: Zafar, Hyola, Traper, RGS003, and Neptune. Employing Life Cycle Assessment (LCA) with the IMPACT2002+ method, the study reveals varying environmental impacts among cultivars, contingent on the selected functional unit. Accordingly, based on one ton of harvested mass, RGS003 emerges as the most pollutant cultivar, while considering 1 ha of rapeseed farms, Traper exhibits the highest environmental impacts. nitrogen-based fertilizers stand out as major hotspots, contributing to over half of the negative effects across various categories. In conclusion, while factors like drought tolerance and disease resistance are crucial in cultivar selection, the environmental performance of cultivars also significantly influences the decision-making process.
