Two field experiments were conducted during the two successive winter season of 2004I2005 and 20052006 at EL-Hoda farm in Wady EL-Mollak. lsmilia Governorate to study the effect of spraying pea plants with yeast extract on growth, yield and quality of produced pods. Results show that the vegetative growth of pea plants i. e., leaves area, plant height. number of leaves and branches as well as fresh and dry weight of leaves and branches per plant were improved by spraying pea plants with yeast extract as compared with the control. Results also clarified that the vegetative growth parameters were gradually increased with increasing the concentration of yeast in spraying solution from 1% up to 3% . Respecting, leaves content of photosynthic pigments, free amino acids. carbohydrates and cytokinins as well as pods yield . pods quality and nutritive value were show the same trend as vegetative growth aspects.
