Inference of the application of polyacrylamide on essential oil and active constituents of lemongrass

Lemongrassis an important aromatic, anti-microbial crop that checks the viability of tumour cell. Citral is its active constituent that is used in preparation of ionones and artificial perfumes. Keeping this in mind, the importance of crop, a pot experiment was conducted as a factorial randomized design to find out the effect of basal application of polyacrylamide on lemongrass. Polyacrylamide is a long chain, synthetic and a high molecular weight polymer. Treatments include six basal levels of polyacrylamide viz.Pam0,Pam224, Pam448, Pam896, Pam1792and Pam3584. The result showed that the basal application of Pam1792 proved best for essential oil, citral content and its yield particularly of variety Krishna.
