Efefct of foliar fpraying with active dry yeast and complete fertilizer [sengral] on growth, yield and fixed oil of [RICINUS COMMUNIS L.]

ABSTRACT

The effect of dry yeast and complete fertilizer [sengral] on Ricinus communis L. plant during two successive seasons of 2000 and 2001 was studied. Four concentrations of foliar spraying with active dry yeast and complete fertilizer [sengral] were used [0, 1, 2 and 3 g/l]. The results showed that spraying active dry yeast and complete fertilizer [sengral] gave the highest values of vegetative growth, fruits and seeds yield as well as fixed oil of the seeds by using the highest concentration of the dry yeast and sengral [3 g/L.]. GLC analysis of oil seed showed that it contains palmetic, stearic, oleic, linoleic, linolenic and recinoleic acids. Active dry yeast or complete fertilizer [sengral] spraying at 3 g/l. On coster bean plants, three times was recommended to obtain fixed oil of high quality and safe of environmental pollution
