Prime Minister Narendra Modi will on Sunday lay the foundation stone for a Rs 10,600-crore brownfield ammonia-urea plant in Dibrugarh district of Assam, giving a fillip to the fertiliser requirement of the entire region. Modi arrived in Assam on Saturday on a two-day trip, during which he is set to unveil multiple projects worth Rs 15,600 crore, around three months before the state is due to go for assembly polls.
