The experiment conducted with an objective to evaluate the effect of different combinations and floor crop nutrition on nut equivalent yield and economics of coconut revealed that interrow spaces of coconut can be successfully intercropped with Nendran banana and papaya and floor crops like turmeric, ginger, amorphophallus and tapioca. Among the different crop combinations, the nut equivalent yield was significantly higher for coconut + banana + turmeric system (687.3 nuts per unit). Results on floor crop nutrition indicated that 75 per cent recommended dose of fertilizers (RDF) for the floor crop resulted in higher nut equivalent yield (519.5 nuts unit-1). Interaction effect was also significant and coconut + banana + turmeric system with 75 per cent RDF for the floor crop turmeric (c1n2) recorded significantly higher nut equivalent yield (738.12 nuts unit-1), gross income (Rs 11,071.8), net income (Rs. 6,291.8) and B:C ratio (2.31).
