Flax cultivation is becoming popular day by day owing to having higher profitability of its cultivation in subtropical humid Himalayan tarai regions. However, the growing technology is yet to properly get quantified focusing the environmental sustainability. Concerning these a filed study was carried out during two consecutive flax-growing seasons of 2019-20 and 2020-21 at Pantnagar with varied nutrient levels and seeding densities. The study was aimed to optimize flax growing technologies in terms of optimum nutrition and seeding density to get better yield and quality with higher nutrient use efficiency. The two-year long experiment was comprised of three levels of seeding densities (1154, 1539 and 1923 seeds m(-2)) and six levels of nutrient management practices (0%N + 100%PK; 100% NPK; 150%N + 100%PK; 200%N + 100%PK; 150%NK + 100%P and 200%N + 100%P + 1 50%K). The seeding density of 1923 seeds m(-2) along with 150% N and K (90 kg ha(-1) N and 45 kg ha(-1) P) + 100% P (30 kg ha(-1)) resulted in better crop growth with optimum height of the plant without lodging problem. This treatment also resulted in optimum flax fibre yield and physical quality of fibre. Positive soil nutrient balance after cultivation and optimum nutrient use efficiencies was also ensured with this innovative management practice. Thus, it can be concluded that the seeding density of 1923 seeds m(-2) along with 150% NK + 100% P is the most suitable management practice ensuring better yield, quality and nutrient use-efficiency for subtropical humid flax grown in Himalayan tarai.
