Lakshmi Narayana 1 Ctcri, Bhubaneswar, Odisha, India The response of cocoyam (Colocasia esuclenta (L.) Schott) to various treatments(Twenty combinations of Treatments) of inorganic and organic amendments were studied under field conditions in 2011 and 2012 growing seasons at farm of the Regional Centre of Central Tuber Crops Research Institute, (CTCRI), Bhubaneswar. Odisha, India. Various enzymatic activities were studied for optimization cornel production. The physio chemical properties of soil quality with effect of integrated use of lime, biological, inorganic and organics on soil micro-flora were statistically analyzed for cocoyam production in lowland of Eastern India. http://pubs.sciepub.com/wjar/2/2/7/wjar-2-2-7.pdf Colocasia esculenta cormels soil fertility dehydrogenase activity alkaline phosphatase fluorescein diacetate hydrolysis assay
