The foliar application of micronutrients increases the yield and oil contents of flax. The present field study was conducted to find out the effect of foliar application of zinc on yield, yield components and oil contents of flax. The experiment was laid out in randomized complete block design with three replications. The 12 different zinc levels viz. control, 0.25%, 0.50%, 0.75%, 1.00%, 1.25%, 1.50%, 1.75%, 2.00%, 2.25%, 2.50%, 2.75% and 3.00% were applied by foliar spray at bud initiation and after capsule filling stage of flax. Zinc was used as a source of ZnSO4. All the zinc treatments significantly improved plant height, stem length, fruiting zone length, fruiting branches, number of capsule per plant, number of seed per capsule, 1000-seed weight, straw yield, seed yield, and seed oil contents compared to control. Therefore, for producing a higher seed yield and oil contents of flax, it is suggested that 3.00% zinc at bud initiation and after capsule filling stage of flax should be used.
