Abstract
All over the world, using natural and safety environmental substances is lofty target to improve quality and quantity of plants. Pot experiments were conducted during summer seasons (2011 and 2012) at the greenhouse of the National Research Centre, Dokki, Giza, Egypt to evaluate the effect of exogenous application of methanol at 10, 15, 20 and 25% and bread yeast extract at 1, 2, 3 and 4% on the growth, photosynthetic pigments, yield, yield attributes, nutritive value, antioxidant activity and fatty acids composition of soybean (Glycine max L. cv. Giza 111). The highest significant increase in plant dry weight was recorded at treatment 4% yeast extract being 82.8% over control, whereas, the least increase was 31.7% over control resulted at treatment 25% methanol. Total photosynthetic pigments was significantly increased at 4% yeast extract by 115.3% over control followed by 3% yeast extract and 20% methanol that enhanced the total photosynthetic pigments by the same degree (77.9%). The highest significant increases in yield and yield attributes resulted at treatments 3 and 4 % yeast extract, since, seeds weight /plant was increased by 90.7 and 106.7%, respectively over control. Meanwhile, increasing in seeds weight/plant was 78.7% over control at treatment 20% methanol. Either methanol treatments or yeast extracts increased oil, protein and carbohydrate, phenolic and flavonoid contents as well as antioxidant activity of the yielded seeds, meanwhile, tannins were decreased. Yeast extracts and methanol treatments at all levels caused marked decreases in total saturated fatty acids accompanied by marked increases in total unsaturated fatty acids. The essential fatty acids (Linoleic acid C 18:2 + Linolenic acid C18:3) were increased by all applied treatments except at 25% methanol. It is worthy to mention that, the enhancement effects of yeast extracts were more pronounced than methanol treatments on soybean growth and yield.
