fertilizers had no effect on the yields of dry roots
(14). Highest root yield of aswagandha was
obtained with the application of 20 kg N and 40
kg P 2
O 5
ha -1 (11). HPLC analysis revealed that
application of 50% NPK + 10 tonnes of farm
yard manure ha -1 gave maximum yield of
forskolin. The statistical analysis revealed that
fresh and dry weights of roots, number of roots
plant -1 and root length were significant compared
to controls and positively correlated with each
other. It is suggested that appropriate dose of
application of fertilizers at appropriate time will
result in higher tuber yield and forskolin content.
Our results also suggest that time of harvest for
optimum yields of tuber is also important.
