The study was conducted at the Soil Science and Agriculture Chemistry Research Farm, School of Forestry and Environment, Sam
Higginbottom Institute of Agriculture, Technology and Sciences (Formerly Allahabad Agricultural Institute Deemed University), Allahabad during
the years 2008 and 2009 in the Rabi season to study the effect of flyash on the physiochemical properties of soil health and mustard crop. The best
treatment combination for growth and yield attributes during both years was observed in S2F2 (Flyash @ 10 t ha-1+ N80P60K40 + S10 kg ha-1).
Maximum concentration of heavy metals was observed in T4 (Flyash @ 15 t ha-1) but was under the permissible limit (Ar 3.9, Cd 37, Cr 300, Pb
400, Mn 1800, Ni 1600). T11 (Flyash @ 10 t ha-1+ N80P60K40 + S10 kg ha-1) showed the best treatment combination in terms of cost benefit ratio.
Therefore it can be concluded that there is an ample scope for safe utilization of industrial waste i.e. flyash in combination with chemical fertilizers
for improving soil fertility, growth and yield of mustard.
