An investigation was carried out to study the effect of intercropping on growth, physiological aspects and yield of taro with constant spacing of 60x45 cm (sole crop), 30x15 cm between (cowpea and French bean) and 35x20 cm (ginger and turmeric) in single and double row planting system. The growth parameters of taro were recorded significantly highest under sole cropping of colocasia whereas petiole diameter was found to be significant in taro with single row ginger. Whole plant fresh weight (531.81 g) and dry weight (106.29 g) were recorded significantly highest under sole cropping. Physiological parameters like leaf area index (2.47) and harvest index (83.15 %) were found highest in taro sole crop at 120 days after planting. At 60-90 DAP, highest net assimilation rate was observed in taro with single row of turmeric (0.003 g m-2 day-1). However maximum corm yield of taro (23.90 t/ha) was recorded from sole crop. Among the intercropped treatments maximum taro yield (19.20 t/ha) was recorded in combination with single row of cowpea.
