Abstract
Ricinus communis belong to Euphorbiaceae family commonly called Castor oil plant. Castor oil plant is cultivated for the seeds which yield fast drying non yellowing oil used mainly in industry and medicines. Castor seeds are large and slow to germinate. Emergence of seedlings may take 7 to 14 days. Nutrient deficiencies in plants have been corrected by using metal chelators. They are more effective than normal salt of these nutrients. In the present study the various doses 20, 50 and 100 ppm of Fe- EDTA and Zn- EDTA shows the germination percentage increase over control and induced growth of shoot and number of lateral roots, but length of root was decreased. 50 ppm of Fe- EDTA and Zn- EDTA gives best effect on seed germination% increase over control i.e (46.67) and (33.33%) over control repectively. The length of Shoot and no. of lateral root increase to a maximum with 50 ppm of Fe- EDTA (4.8 cm and 29.6 cm respectively) and with 50 ppm of Zn- EDTA ( 4.2 cm and 25.8 respectively).
