Abstract
A field experiment was carried out at Experimental Farm of Soil and Water Research Department, Nuclear Research Centre, Atomic Energy Authority, Inshas Egypt, to follow up the effects of different doses of gamma ray on castor bean (Ricinus communis L.) grown on a sandy soil and irrigated with either fresh water or wastewater from El-Gabal El Asfar. Irradiation resulted in higher values of both fresh and dry weight of castor bean. This effect seemed more obvious by increasing the dose of gamma ray up to 50 Gy beyond which a gradual decrease occurred. Nitrogen, phosphorus and potassium contents in castor bean under the effect of gamma irradiation were arranged in the following descending order; 50Gy > 100Gy > 150Gy > 200Gy > 0 > 250Gy> 300 Gy. Nitrogen, phosphorus, potassium and oil contents in castor bean plants irrigated with wastewater were higher than the corresponding ones in plants irrigated with fresh water.
