Abstract

Flax is one of the earliest plants that has been domesticated by humans Due to high amounts of omega-3 fatty acid its cultivation and consumption is increasing as a healthy oil resource In nutritional point of physiology zinc and nitrogen are two important elements in plant biosynthesis So in this experiment effects of three levels of nitrogen 40 60 and 80 kg ha and two levels of zinc sulfate control and 3 1000 on five flax cultivars in split factorial based on randomized complete block design was investigated The results showed that genotypes in terms of height capsul number seed yield and biological yield revealed significant differences P kg nitrogen and 3 1000 zinc sulfate spray
