EVALUATION OF PHYSIOLOGY AND BIOCHEMISTRY THE CASTOR BEAN FUNCTION OF DOSES AND FERTILIZER IN SOIL

Aimed at with this work to investigate the physiology and biochemistry of the castor bean, after use of compost and organic castor bean. The trial began on October 3, 2005 ending on March 20, 2006, in green-house, controlled environment of the National Center of Cotton Research (CNPA / EMBRAPA), in Campina Grande , State of Paraiba. Was used to cultivate castor BRS Paragua u. We used a randomized block design with four replications, totaling 11 treatments, since they are derived from doses of castor-oil and organic compost (four doses of each) and three witnesses, with further study of orthogonal contrasts . The castor bean showed effective results in the variables chlorophyll content (ppm) in leaves and number of days to flowering of the first cluster (DIAFI). Compost organic waste not produced any significant result for both variables.
