Abstract

Two field experiments were carried out at the farm of Ismailia Agricultural Research Station during 1990 and 1991 seasons to study the effect of Mn application methods on the yield as well as oil percent­age and total oil yield of rape seed in sandy soil. Results showed that seed coating treatment significantly in­creased seed yield by 76.09% and total oil yield by 99.44 %, respective­ly over those obtained from the control. Mn-application by soaking at pH 4 increased seed yield compared with those at pH values 6 and 8. Spraying Mn at different pH values, resulted in a gradual increase in crop yield. The highest yield was obtained at Ph 8. Application of 0.30 g Mn in the form of EDTA/kg seed by the pH coating method is consid­ered to be satisfactory for rape seed planted in sandy soils.
