The effect of flax seed inoculation by Azospirillum brasilense on flax yield and its quality

Abstract

Field experiment demonstrated the benefit resulting from biological soil management including the use of N2-fixing and growth promoting bacteria A. brasilense B-4485 for long-fibred flax. Seed inoculation by A. brasilense B-4485 was equivalent to the introduction of 15 kg/ha of N that provided the possibility of partial flax N requirement supply. Treatment A. brasilense + N15P60K90 is considered to be the most profitable management in regard to flax yield and its quality, and is comparable to N30P60K90 treatment. Biological management allows preventing high concentrations of N in soil, excludes lodging and negative effects on flax yield and its quality. Implementation of biological management for flax nutrition may be profitable for both ecology and economy of long-fibered flax growing.
