Abstract: To evaluate the efficiency of tank silt with organic manures, pot culture experiment was conducted at Pandit Jawaharlal Nehru College of Agriculture and Research Institute, Karaikal using bhendi as a test crop with 13 treatments, wherein absolute control and recommended dose of fertilizer (RDF) was compared with application of tank silt (TS) alone @ 2 t ha-1 and different organic manures viz. pressmud (PM), sewage sludge (SS), water hyacinth compost (WHC), FYM and spent wash (SW) @ 2 t ha-1. The same set of treatments were repeated with 100 per cent RDF. The results revealed that the fruit yield was higher with TS+PM+ remaining through fertilizer (RTF) and it was comparable with RDF, TS+RTF, TS+SS+RDF and TS+PM+RDF. The contents of nutrients in the fresh fruit had shown that the N, P and K was higher when tank silt was applied with FYM+RTF. While the content of Ca remains unaffected due to imposed treatments, the Mg content was higher with application of TS+SS+RTF. The content of S was higher in the treatment TS+PM+RTF. The uptake of N was found to be higher with TS+FYM+RTF. In case of P uptake, it was comparatively higher in the treatment which received TS+SS+RDF. However, in the case of K uptake, higher uptake was associated with 100 per cent RDF, TS+RTF and TS+PM+RTF which were comparable. As regards the Ca uptake, application of TS+RTF and TS+SS+RDF recorded higher values. It was also noticed, that addition of tank silt alone or with spent wash or with sewage sludge could register higher uptake of Mg. The uptake of S was found to be relatively higher in the pots which received TS+WHC+RTF.
