Influence of biofertilizers on growth and some biochemical aspects of flax cultivars grown under sandy soil conditions

Abstract

Application of biofertilization treatments (Mycorrhiza, milk whey, yeast, and yeast extract as soil drench or foliar application, respectively) affects significantly most of the studied characters. Data show significant variations in vegetative growth parameters, photosynthetic pigments, carbohydrate, phenolic content, as well as seed yield, yield components, and nutritive value (oil, protein, flavonoid, and phenolic content) of the yielded seeds between three flax cultivars. Sakha-1 cultivar showed more adaptation to the conditions of sandy soil than the linola and Line-3 cultivars and reflected on the highest significant value of seed yield. All applied treatments caused significant increases in seed yield and its components of three flax cultivars under investigation. Sakha-1 cultivar showed the highest significant increase in seed yield/fed due to yeast extract treatment followed by milk whey treatment. Further, mycorrhiza treatment significantly increased seed yield of linola cultivar. Regarding Line-3, the highest significant increase in seed yield/fed was obtained by milk whey and yeast extract treatments respectively.
