Abstract

Elephant foot yam (Amorphophallus paeoniifolius (Dennst.) Nicolson) is a high potential tuber crop widely cultivated in tropical Asia and Africa and belongs to Araceae family.   It is a robust herbaceous plant with a height of 1.0-1.5m with dissected tripartite leaves thick, single, upright petiole (pseudostem).   The corms are a delicacy and widely used in Ayurvedic medicines for curing of asthma, piles, dysentery, vomiting and stomach disorders and also rich in nutrients used as a drug in the context of dietetics and medicines (Raghu et.al., 1999). The optimal use of water and organic nutrients are pre- requisite to maximize the productivity in terms of return. Hence, the trials were conducted through AICRP on tuber crops to standardize the nutrient management technology in agro-climatic conditions of Tamil Nadu. Integrated nutrient management studies on yield and quality of elephant foot yam cv. Gajendra showed that plant height ranged between 39.53cm and 65.27cm. Tallest plants (65.27cm) were recorded in 100% RDF (as inorganic) 80:40:100 kg NPK/ha followed by application of 75% RDF (as inorganic) + 25% RDF (as organic) + PSB @ 5 kg/ha + Azospirillum 5 kg/ha (57.15cm). In East-West and North-South directions, maximum canopy spread was observed with application of 100% recommended dose of fertilizers (80:40:100 kg NPK/ha) through inorganic source. Highest corm yield (53.47 t/ha) was recorded with application of 75% RDF (as inorganic) + 25% RDF (as organic) + AMF @ 5 kg/ha + Azospirillum @ 5kg/ha. Whereas oxalic acid was observed highest (102.49 mg/100 g) in 100% RDF (as inorganic) 80:40:100 kg NPK/ha followed by 50% RDF (as inorganic) + 25% RDF (as organic) + AMF @ 5 kg/ha + Azospirillum @ kg/ha (96.30 mg/100g) and lowest (89.89 mg/100g) observed in 75% RDF (as inorganic) + 25% RDF (as organic) + AMF @ 5kg/ha + Azospirillum @ 5kg/ha.
