Four treatments viz., T₁: 75% of recommended NPK fertilizer + organic recycling with vermicompost. T₂: 50% recommended NPK fertilizer+ organic recycling with vermicompost + vermiwash application + bio fertilizer application and in situ green manuring. T₃ (Fully organic): Organic recycling with vermicompost + vermiwash application + bio fertilizer application, in situ green manuring & green leaf manuring (Glyricidia lopping’s) + Composted coir pith and mulching with coconut leaves. T₄ (Control): Mono crop of coconut with recommended NPK fertilizer and organic manure were laid out in non-replicated trial. Experiment results revealed that treatment T₃ (Fully organic) has produced the highest average yield of coconut (8056.67/ha), cocoa (224.20 kg/ha), lime (1010.55 kg/ha), Drumstick (798.75 kg/ha), banana (10411.67 kg/ha) Gross return (Rs.2,47,627/ ha) and net return (Rs.1,58,975/ ha).
