An experiment was conducted for five years in a 45 years old coconut garden of East Coast Tall variety planted with a spacing of 7.5 m x 7.5 m to evaluate the nutrient management in coconut based cropping system of Thanjavur region during 2013 - 2018. The coconut based cropping system comprises of Coconut (ECT) + Black pepper (Panniyur 1) + Banana (G9) + Cocoa (F1 hybrid)) in East Coast region of Tamil Nadu with four nutrient management treatments viz., T1 – 75 % of recommended NPK + 25 % of N through organic recycling with vermicompost, T2 – 50 % of recommended NPK + 50 % of N through organic recycling with vermicompost + vermiwash + biofertilizer + in situ green manuring, T3 – Fully organic 100 % of N through organic recycling with vermicompost + vermiwash + biofertilizer + in situ green manuring + green leaf manuring (Glyricidia leaves) + composted coir pith husk incorporation (once in 3 years) and mulching with coconut leaves, T4 – Control (recommended NPK and organic manure). The number of nuts of coconut, cocoa, pepper and banana yields were significantly influenced by the inorganic and organic nutrient management in coconut based cropping system. The mean nut yield of 118 number of nuts palm-1, dried cocoa beans 230.20 kg ha-1, fruit yield of banana 23,345 kg ha-1 and dried black pepper 39.80 kg ha-1 were registered in treatment T2 – 50 % of recommended NPK + 50 % of N through organic recycling with vermicompost + vermiwash + biofertilizer + in situ green manuring with the highest net income of Rs. 354244 /-. The mono crop of coconut registered the lowest net income of Rs. 1,18,645/-.The study indicated the nutrient management with 50 % inorganic fertilizer and 50 % organic recycling are suitable for coconut based cropping system.
