A pot experiment was carried out to study the influence of press mud application at 0, 10 and 20 tons per hectare using four soils representing black, red, alluvial and lateritic soils and finger millet (ragi Co 10) as test crop. The results showed progressively significant increase in grain yield with increasing levels of press mud in lateritic and rod soils whereas in the case of black and alluvial soils the vield increased significantly with application of 10 tons press mud perhectare and there was no further increase with the higher level of press mud. The uptake of nutrients N, P and K also showed significant inorceaca with press mud application and this was more pronounced in the red and lateritic soils then in the black and alluvial soils. The soils were left generally with a higher or at least equal available nutrients status in the press mud tretments in spite of the higher yields as compared to the control.
