A field investigation was carried out at Instructional farm attached to College of Agriculture, Vellayani, Kerala during 2015-16 to study the effect of tillage and nutrition for quality enhancement in tannia. The experiment was in split plot design with four replications. The treatments consisted of tillage and planting systems 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 soil conditioners (s1- control, s2- coir pith, s3- rice husk) combined with two nutrition systems (n1- integrated nutrient management (INM) and n2- organic nutrition). Results of the experiment revealed that the quality characters of tannia was improved by deep tillage with pit system of planting, application of coir pith as soil conditioner @ 500g plant-1 and organic nutrition (FYM @37.5 t ha-1 + wood ash @ 2 tha-1).
