Quality augmentation through tillage and nutrition in Tannia (Xanthosomas agittifolium (L.). Schott)
Abstract: A two-year field study was conducted at the Instructional farm attached to College of Agriculture, Vellayani, Kerala during 2014 to 2016 to study quality augmentation through tillage and nutrition in tannia. The design was split plot and it was replicated four times. The treatments were 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). Results of the experiment revealed that the quality characters of tannia like, total dry matter production, harvest index, cormel dry matter, starch, protein and shelf life can be augmented by adopting deep tillage with pit system of planting, applying coir pith @ 500g plant-1 as soil conditioner and by providing organic nutrition (FYM @ 37.5 t ha-1 + wood ash @ 2 t ha-1).
