ABSTRACT
A field experiment was conducted at Mukuperi village in Thoothukudi district of Tamil Nadu, South India in 2018, which is situated at 8.5649 latitude and 77.9910 longitude, to study the effect of different organic amendments on soil and the impact of Green gram. The treatments of this study were Vermicompost {VC}, Farm yard manure {FYM} and Poultry manure {PM} and their combinations at three different concentrations 8.5, 12.5 and 16.5 t ha-1. The organic amendments were applied and after the harvest of the crop, the soil samples were taken from each plot and examined. The values of pH and Electrical conductivity {EC} were found to be minimum in Vermicompost treated soil. The values of Nitrogen {N}, Phosphorus {P}, Potassium {K} and pod yield were significantly increased. Thus, the additon of organic amendments was found beneficial for sustaining soil fertility and enhancing the crop yield.
