Dynamical fluctuation of target evaporated black.particles.is.inves.igated in both forward and back.ard hemis.heres.within the framework.of multi-dimens.onal factorial moment methodology us.ng the brilliant concept of the Hurs. exponent. We analys. the black.particles.emitted in ^32s.AgBr interactions.at 200AGeV and it is.evident that the dynamical fluctuation in the back.ard hemis.here is.s.lf-affine. In the forward hemis.here, dynamical fluctuation is.s.lf-s.milar but not s.lf-affine. However, s.udy indicates.that the fluctuation in the forward hemis.here is.more pronounced than that in back.ard hemis.here.

A field experiment was.conducted from 2002-2005 on a s.ndy clay loam red and lateritic s.il under irrigation in a farmer＇s.field at s.nk.pur （Lat. 23°36.79′ N, Long. 87°38.14′E, Elev. 46 m AMs.）, Birbhum, Wes.
