While @Future cannot be called from a batch class, a web service can. A web service can also call a @future method. So have your batch class call an apex web service that in turn calls your @future method.
There is one trick here. To call your web service from the batch class, you need a session Id. Don't call Userinfo.getsessionid from a scheduled batch class. You won't get a result. Instead, call Userinfo.getsessionId from your schedulable class and pass the id into your batch class as a parameter. Now you have everything you need to call @Future from a batch.

This may be workaround, But I want to know the reason behind it . If the batch class and future method both are asynchronus process then why we cannot call future from batch.
