Yes, it is Pennisetum purpureum, commonly called Napier grass. 

I cannot express in writing how i am thankful to you. I have one earlier post of similar looking grass and i think that is also P. purpureum - https://groups.google.com/d/topic/indiantreepix/vX0f8PbsgTg/discussion

Yes. That is also the same. However, under cultivation, there are also hybrid napiers which are man made hybrids of Pennisetum purpureum and P.americanum (Bajra). Their seeds will not be fertile.
Manoj why would they be hybridized? for what purpose?
ANd I have one more silly question... 
how does our Indian Bajra become p. americanum????? american?? 
I found a well written paper at this site for the hybridization and its utility in animal husbandry ...
http://www.maralika.com/GRASS.html
When i searched the net for Pennisetum species in West Bengal i came across the cultivated hybrid of the two Pennisetum species as you have mentioned here. But, i think this grass is no more cultivated in our locality, instead i have seen cultivation of another fodder grass and i have a post of that species too, at - https://groups.google.com/d/topic/indiantreepix/uYhS81NOivo/discussion.
It is just a nomenclature change. Earlier, Indian and African Bajra was known as Pennisetum typhoides. There was another species called P.spicatum from Africa, which later on was found to be just a variation of Pennisetum americanum, which is based on the originally published Panicum americanum Linn. published in 1753. A detailed study of P.americanum and P.typhoides from different areas and by different authors finally led to the consensus that both of them have several variations which are continuous in nature and hence should be considered as the same species. By rule of priority of publication, Pennisetum americanum (Linn.) K.Schum. was accepted as the correct name of pearl millet (bajra).
