Abstract:

Ashwagandha (Withania somnifera L. Dunal) is an important medicinal plant containing active constituent withanolides providing anti-stress ability, energy, and immunity. An experiment in Randomized Block Design (factorial) was laid out at medicinal and aromatic plants farm, AAU, Anand to study the effect of individual five endophytic bacterial isolates on growth and yield of W. somnifera along with FYM and with/without recommended dose of fertilizer (RDF 30:15:0, N:P:K kg/ha). Amongst two levels of fertilizer doses, F1 receiving RDF was superior to F0 control. Pseudomonas aeruginosa showed significantly higher yield and yield attributing parameters viz. plant height (104.45 cm), no. of branches (6.50), root length (29.85 cm), root girth (6.40 cm), green leaves yield (22698 kg/ha), dry root yield (480 kg/ha) and dry foliage yield (8574 kg/ha) when compared with un-inoculated control (72.30 cm, 4.00, 19.42 cm, 4.35 cm, 7907 kg/ha, 280 kg/ha, 5704 kg/ha), respectively. The results indicated that soil application of endophytic bacteria @ 1L/ha as well as RDF (30:15:0 NPK kg/ha) improved dry root quality parameters starch and withanolides. Endophytic P. aeruginosa strain AAU K5 proved to be the best plant growth promoting endophytic bacteria for Ashwagandha.
