Aims: The present work aims to stimulate some physiological changes in the plants using organic fertilizer and compost by enhancing some compounds such as total amino acids and phytohormones in two cultivars of bean.

Study Design: The pots of the (Phaseolus vulgaris) L. cv. bronco were divided into 7 sub-groups they will be prepared as in the seven treatments  via1- control , Nile compost ,compost and rice straw , compost and maize stalks , rice straw and maize stalks , rice straw , maize stalks and  were replicate times for Phaseolus vulgaris L. cv. paulista from T₈-T₁₄. After 45 days (vegetative stage), 90 days for (flowering stage) and 130 days for (fruiting stage) the plants were harvested.

Place and Duration of Study:  Department of Biological and Geological Science, Faculty of Education, Ain Shams University, Cairo-Egypt June 2012.

Methodology: Growth, yield, free amino acids and phytohormones of two cultivars of Phaseolus vulgaris L. cv. paulista and cv. bronco was investigated.

Results: The results showed that the significant differences in growth in all the stages and percent of free amino acids and phytohormones in shoot in vegetative stage in two cultivars of bean were obtained with mixture of compost or maize stalk and maize stalk decompost.

Conclusion: Generally, the addition of organic fertilizer with compost led to improve the yield of two cultivars as compared to control. Hence, it could be suggested that the treated plants, with these organic residues and Nile compost increased the growth, yield and the above chemical compositions
