In soils with hard pan sub soils chiselling increased the non-capillary porosity at the sub surface (20-40 cm) from 5.6 to 10.0 per cent. At this depth the bulk density decreased from 1.76 Mg m' to 1.66 MG m', the hydraulic conductivity improved from 1.4 to 2.7 cm hr. Chiselling resulted in improved grain yield by 35.5% over the control (6.09 q ha). Addition of pressmud at 10 t ha" and coirpith at 5 t ha over and above chiselling increased the grain yield by 37.9 and 56.4 per cent over the control respectively.
