Effect of microbial inoculants in combination with organic manures and inorganic fertilizers on yield and quality of coleus.

Ashwagandha or Asgandh (Withania somnifera L. Dunal.) popularly known as ‘Indian Ginseng’ belongs to the family Solanaceae. It is found in wild state in the Mediterranean region of North Africa. In India it is mainly cultivated in Mandsaur district of Madhya Pradesh, adjoining villages of Kota district of Rajasthan, Punjab and Karnataka. Ashwagandha roots and occasionally its leaf and seeds are used in ayurvedic and unani medicines preparations (Majumdar, 1955). The total alkaloid content of the Indian ashwagandha roots is reported to vary between 0.13 to 0.31 per cent. Apart from roots, alkaloids have also been reported in leaves and berries (Sreerekha et al., 2004). The roots are prescribed in medicines for hiccup, several female disorders, bronchitis, rheumatism, dropsy and stomach, lung inflammation and skin diseases. They are mostly used for curing general and sexual disabilities. Roots are having anti-aging property (Savitha et al., International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 7 Number 09 (2018) Journal homepage: http://www.ijcmas.com

Effect of Organic Manures and Bio-Inoculants on Growth, Dry Root Yield and Quality in Ashwagandha (Withania somnifera L. Dunal.)

An investigation was carried out to study the effect of organic manures and bio-inoculants (Azatobacter, Azospirillum, PSB and VAM) on yield, quality and economics of ashwagandha by comparing with RDF at K.R.C.C.H. College of Arabhavi. The results showed that yield parameters viz number of berries per plant (219.33), seed yield (3.15 q/ha), fresh root (19.58 q/ha) and dry root yield (5.88 q/ha) recorded maximum with the application of RDF + VAM, Quality parameter like root length and root diameter recorded maximum (27.07 cm, 1.88 cm, respectively) in T3-RDF (N:P:K-40:50:40 kg/ha) + FYM (5 t/ha) + VAM (25 kg/ha), which was on par results of T1, T7 and T5. Maximum total alkaloid content (0.31%) recorded in T7-FYM (5 t/ha) + Azotobacter (625 g/ha) + Azospirillum (625 g/ha) + PSB (625 g/ha) + VAM (25 kg/ha) + (Panchagavya-3% + Amruthapani-3% at 15 days interval up to harvest of crop), however treatments T3, T1 and T5 have shown on par results and gross return (Rs.119700/ha), net return (Rs.1,02,066/ha) and B:C ratio (6.78), however the organic treatment T7 have shown on par results in growth, yield parameters and economics.
