The experiments with eight growing media as treatments were conducted in CRD with three replications at Garacharm Research Farm, ICAR-Central Island Agricultural Research Institute, Port Blair during 2017-19 in a naturally ventilated polyhouse from November to March with tomato hybrid ‘Arka Rakshak’ in grow bag (12 L). Eight treatments include cocopeat + vermiculite (1:1), cocopeat + perlite (1:1), cocopeat + sand (1:1), cocopeat + saw dust (1:1), cocopeat + vermiculite +saw dust (1:1: 2), cocopeat + perlite +saw dust (1:1:2), cocopeat + sand +saw dust (1:1:2) and soil + farmyard manure (FYM) (3:1). Results showed that among different growing media, cocopeat + saw dust (1:1 v/v) recorded maximum number of fruits/plant (12.33), fruit weight (51.2 g/fruit), and finally fruit yield (631 g/plant)and was at par with cocopeat + vermiculite + saw dust (1:1:2). However, cocopeat + saw dust (1:1 v/v) combination was cheaper than cocopeat + vermiculite + saw dust (1:1:2). Maximum Total soluble solids (TSS) of 6.75 ºBrix was recorded by cocopeat + saw dust (1:1 v/v), whereas higher ascorbic acid (16.46 mg/100 g) and lycopene (6.8 mg/ 100 g) contents were recorded by cocopeat + vermiculite (1:1). Growth, yield and quality parameters recorded in the control i.e., soil + FYM were least. Hence, it can be concluded that cocopeat + saw dust (1:1 v/v) as economically and environmentally sustainable media for soilless cultivation of tomato under island condition.
