Abstract

Growth and yield performance of five swamp taro (Colocasia esculenta) cultivars viz., BCST2, BCST4,BCST15, BCST21 and BCST23 were assessed under natural, swampy, waterlogged conditions. Despite decline in leaf water potential (LWP) due to pre-monsoon dry spell, the cultivar BCST15 showed consistently better runner yield in all the harvests as compared to the other cultivars. The cultivar BCST15 maintained greater plant height, greater leaf area for longer period of crop growth and greater leaf chlorophyll content. The total runner yield was highest in BCST 15 (5.96 t ha-1) followed by the cultivar BCST4 (3.15 t ha-1) and lowest in BCST 21 (1.72 t ha-1). Therefore, the cultivar BCST15 was found suitable for cultivation in swampy, waterlogged environment due to better growth and higher yield than other cultivars.
