Abstract
A field experiment was conducted to sttidy the efl'ect of composted coirpith, composted
pressmud, farmyard manure and NPK on soil enzyme activities and nutrient status of post
harvested soil o f clusterbean. The experiment consisting o f twelve treatments (Tj- Control,T2-
Composted coirpith (12.5t ha T3- Composted pressmud (12.5t ha"'), T 4 - Farmyard manure

pressmud (6.5t ha'') + Farmyard manure (6.5t ha'') was laid in a pot having 7kg soil (per pot)
with three replications. Dehydrogenase and the urease enzyme activity of the soil with ditTercnt
treatments used for the productivity of cluster bean was high in all the treatments but the
maximum was found in T,2 (Composted coirpith (6.5t ha'') + Composted pressmud (6.5t ha'') +
Farmyard manure (6.5t ha'') followed by T9 (Composted coirpith (12.5t ha'') + 25% NPK) when
compared to the control T,. pH o f the post harvest soil of cluster bean was maximum in Tg
(Farmyard manure (12.5t ha'') + 50% NPK), while all other nutrients (electrical conductivity
(millimhos cm''), organic carbon (%). available nitrogen (Kg ha''), available phosphorus (Kg ha'
'), available potassium (Kg ha''), sulphur (ppm) and available micronutrients (copper (ppm), zinc
(ppm), iron (ppm) and manganese (ppm)) were maximum in Ti2(Composted coirpith (6.5t ha'' ) +
Composted pressmud (6 5t ha'') + Farmyard manure (6.5t ha'') when compared to the control 'f|
in post harvest soil o f cluster bean.
