Tannia is one of the six most important root and tuber crops grown world-wide. Tannia possess good keeping quality compared to other vegetables. The tubers are considered more nutritious than colocasia and potato. But the crop is still under-exploited compared to other tuber crops. Hence the study was undertaken to identify the effect of tillage and nutrition on quality characters of tannia. Methods: A field experiment was conducted at College of Agriculture, Vellayani, Kerala during 2014-15 to

The treatments consisted of tillage and planting methods as main plot treatments (L1- conventional tillage followed by pit system, L2- conventional tillage followed by mound system, L3- deep tillage followed by pit system and L4- deep tillage followed by mound system). The sub plot treatments were combinations of soil conditioners (S1- control, S2- coir pith, S3- rice husk) and two nutrition systems (N1- integrated nutrient management (INM) and N2- organic nutrition). Result: Results of the experiment revealed that the quality characters of tannia was improved by deep tillage to a depth of 30 cm followed by pit system of planting, application of coir pith as soil conditioner @ 500 g plant-1 and organic nutrition (FYM @37.5 t ha-1 + wood ash @ 2 t ha-1).
