AbstractA field experiment was carried out using groundnut variety VRI 2 in coastal sandy soil in Pichavaram coastal village near Chidambaram which represented sandy texture and had a pH-7.44, EC-0.12 dSm-1 and available NPK of 139, 15 and 143 Kg ha-1, respectively. The experiment conducted were nine treatments viz., T1 – Absolute control, T2 - 100% RDF Alone, T3 - 125% RDF Alone, T4 - 100% RDF + Press mud @ 10 t ha-1 + Sea weed extract, T5 – 100% RDF + Vermicompost @ 6 t ha-1 + Sea weed extract, T6 – 100% RDF + Coirpith Compost @ 6 t ha-1 + Sea weed extract, T7 – 125% RDF + Press mud @ 10 t ha-1 + Sea weed extract, T8 – 125% RDF + Vermicompost @ 6 t ha-1 + Sea weed extract, T9 – 125% RDF + Coirpith Compost @ 6 t ha-1 + Sea weed extract. The result revealed that application of 125% RDF + Press mud @ 10 t ha-1 + Sea weed extract (T7) recorded higher values in parameters viz., plant height (63.30cm), Leaf area index (1.48), Number of leaves (45.30), Dry matter production (3816), Pod yield (2157), Kernel yield (1119), nitrogen uptake (68.92), phosphorus uptake(12.64), Potassium uptake (12.64), Calcium uptake (61.57), Magnesium uptake (23.64) and BC ratio (2.88).
