Best way to show foreign income as Indian Income

I am planning to move to india after long stay abroad, I am paying tax for my income abroad.

I am aware that there is a RBI restriction on utilization of foreign funds in some sectors e.g. Agriculture.

I am planning to be a agriculturist.

Question is:

1) Is RBI law applicable to all ( individual/companies) ?

2) How can I invest the Foreign earned money in india (e.g: Agriculture), staying within the legal limits ?

Thanks in advance.

(sorry, I was not sure which category this question should be ! )
