In an order issued here today, District Magistrate Pardeep Sabharwal said the ban has been imposed on "cultivation of Bt cotton and particularly crops with tall height, orchards and tree near the international Indo-Pak border beyond the barbed fencing".
All the farmers have been told to comply with the orders strictly forthwith.
The orders were passed to prevent drug smuggling and infiltration, an official release said.
The district administration also banned constructing buildings within a kilometer of the fence wire.
