Effect of fertigation on growth, yield and nutrient uptake in elephant foot yam Amorphophallus paeoniflorins (Dennest.) Nicolson

The field experiment was conducted to elicit information on the yield and nutrient uptake of elephant foot yam [Amorphophallus paeoniflorins (Dennest.) Nicolson] under fertigation at orchard, Department Vegetable Crops, TNAU, Coimbatore during year 2012-2013. laid out in randomized block design with three replications. growth attributes viz., plant height, canopy spread, leaf area, pseudo stem girth were found be highest T5 receiving 75% RDF through (50 % straight fertilizers + 50% water soluble fertilizers) fertigation. are corm weight, diameter, number cornels, root number, length diameter also recorded treatment T5¬ [75% (50% followed by T4 which receives 100% Increased content corms observed (T5) (T4). BC ratio higher [fertigation fertilizers)] 3.96.
