Two filed experiments were carried out at Giza Agric Res. Station, Agric Res. Center, Giza, Egypt, during 2000/2001 and 2001/2002 seasons to investigate the effect
of four levels of Zinc (0, 5. 10 and 20 kg 1 fed) and mycorrhizal fungi on yield and quality
traits of three flax varieties (Sakha 1 ,Belinka and Bombay). Data revealed significant differences among flax varieties of straw, seed yields
and their components as well as quality characters. Sakha 1 flax variety significantly
produced the highest values of straw yield and its components as well as the highest
fiber length, capsules number Iplant, seed index, seed yield 1 plant, seed yield !fed oil
percentage and oil yield Ifed. The application of 20 kg Zn !fed significantly increased
straw yield 1 plant and per fed, capsules number Iplant, oil percentage, fiber percentage,
fiber fineness and fiber yield !fed. Whereas, seed yield! plant, seed yield !fed, seeds
number! capsule, seed index, oil yield / fed and fiber length were significantly increased
by increasing Zinc level up to 10 kg ! fed Varieties x Zinc levels interaction had a
significant effect on straw yield, seed yield, fiber yield and their components. Also,
varieties x inoculation interaction had significant effect on straw yield, seed yield and their
components and fiber yield. Varieties x Zn levels x inoculation interaction had a
significant effect on all studied characters. In general, it must be concluded that
cultivation of flax after maize or inoculation with VA mycorrhizal fungi with the application
of 10 kg Zn 1 fed gave the highest straw yield, seed yield and oil yield.
