Field experiment was conducted in a farmer’s field at Ponnanthittu village in Cuddalore district of Tamil Nadu to find out the influence organic manure and NPK on the soil properties and yield of groundnut in coastal sandy soil. Different organic manures viz., Control, Farm yard manure @ 12.5 t/ha, Composted coir pith (CCP) @ 12.5 t/ha, Casuarina leaves @ 10.0 t/ha and Dhaincha @ 10.0 t/ha were applied as main treatments and different NPK levels viz., 75 per cent, 100 per cent, 150 per cent and 200 per cent of recommended NPK for groundnut was studied as sub treatments in Factorial Randomized Block Design with three replications. Groundnut var. VRI 2 was grown as test crop. The results of the study indicated that application of different organics significantly reduced the pH, salinity and increased the nutrient availability of soil. Among different treatments, application of 150 per cent NPK along with 12.5 t/ha of composted coir pith significantly increased the growth and yield of groundnut.
